I’m a few months late on the six-year anniversary of this blog but finally found some time. (For year 5 go here) It was seemed to be another quiet year on the blog because it was not a quiet year for work or other aspects of life. The DAWNDINOS project got into full swing and there will be a lot more about that soon on that website and maybe here, too.

Freeezersaurus 2 has been mostly vacated now; and Freezersaurus 3 is in place, with the contents shifted– and a mad rush in action to get rid of (boil down + varnish bones of) as many specimens as I can! I have way too many… of course, mostly elephant bits. Here are the last big bits left in Freezersaurus 2; we are intimidated to move them…

Stomach-Churning Rating: 3/10 until the opossum-digested-by-gator at the end, then 9/10, so hang tight!

Year 6 began with a post about a new paper! We published a big synthesis of data on what mammals turn their kneecaps into bone (or not), and how those states evolved. The story turned out pretty interesting and we are still pursuing some angles that it inspired, so stay tuned! Otherwise, the kneecap project (i.e. Leverhulme grant) has ended and staff/students have moved on (but published all their papers on it– well done, Sophie, Kyle and Viv!!), so it will fall quiet on that topic for a while.

Then we published another paper, and it happened to involve more sesamoid-y stuff! But with birds and their ankles, and some tantalizing evidence of soft tissue and organic biomolecular preservation. I’m still a bit amazed this paper happened and am pleased we got to collaborate on it.

Next, I got to ramble on a bit, about another serious topic related to science– this time, on blame.  I had forgotten about that post, and now on re-reading it it has fresh new relevance to me. All the more reason to keep blogging!

Smaller but better: Freezersaurus 3, part of a proud dynasty!

But then, what do you know, we published another kneecap paper! And on ostriches! With some simple but ambitious finite element analysis. We are meaning to get back to this approach… it just scratched the surface of some super cool “mechanobiology” that could shed light on “evo-devo”.

And next, BOOM! The dinosaurs dawned. By which I mean my current ERC grant “DAWNDINOS” began. Do take a look– the website now has some lovely NEW palaeo-art by Bob Nicholls, John Conway and Scott Hartman, with more to come! This project’s inception led to an inspection of caeca in tinamous; the following post.

I managed to have some summer holiday in the midst of the year, and that made an extremely memorable “pilgrimage” to a fossil site possible– “Experiencing the Irish Tetrapod Tracks” was the blog post that emerged from the waters. (That post needs a little revamp in light of some other literature; I will get around to that soon)

DAWNDINOS got a nice new 3D printer and we’re gradually printing up some archosaurs to show.

Holiday ended and back to the freezer I went, to post about how we thaw specimens (and how odd wallaby legs can be). Then we published three papers in quick succession and I played catchup posting about them (Mussaurus forelimbs; mouse vs. human hindlimb simulations; and tetrapod forelimb musculature).

Speaking of mouse hindlimb simulations, I didn’t blog about this related paper that we published earlier in 2018, but it’s very relevant. And GIF-worthy!

But I couldn’t stay away from bird legs for long, and so soon enough I posted “The Bird Knee Challenge“, which still stands.

Jumbo the elephant loomed into view at Christmas-time (plus a documentary about T. rex with Chris Packham, and another about Hannibal’s elephant excursion over the Alps– the latter also playing on PBS in USA); all featuring cameos with me, so I posted about the Jumbo/Attenborough one. That’s another life experience I will treasure.

Next, back to musing about science and humanity– and who’s a more big-name, very relatable human scientist than Darwin? Well, we could debate that endlessly but I posted about Darwin’s human nature for Darwin Day.

That takes me through to March 2017. I’ve posted a little more since then but that counts as Year 7 of this blog, so we’ll catch up with that then. Looking back on ~2017, I posted more blog posts than I thought I did! Maybe it’s just that 2018 feels very quiet to me blog-wise. We’ll see how it shapes up though.

Years ago, my team dissected an alligator (for Allen et al. 2010,2014 papers if you are keeping track) that had an opposum in its stomach, during winter when feeding wasn’t supposed to be happening much. So that came up again this year; and hopefully it does not make anything come up from your stomach. But this is real anatomy in action.

If you’re in London, you still have almost one week left to hurry to the Valence House in Dagenham and see a great exhibit on Ray Harryhausen’s dinosaurs and other cool “Dynamation” stop-motion models and art!

This blog post is a photo tour of what I saw, in case you cannot go.

Like it? Click it. Bigger pic.

Stomach-Churning Rating: 1/10 nice stop-motion animation models. Medusa won’t hurt you here.

I loooooooooooove Ray Harryhausen’s work, ever since I was a child and saw “Jason and the Argonauts” and many other films, plus “Clash of the Titans” once it came into theatres. There is the attention to detail in anatomy and locomotion, and the wondrous fantastic nature of even the more mundane creatures he animated, and the rich mythology that he drew from to inspire his creations. Modern CGI is great in a different way, but nothing I can think of in recent special effects truly beats (1) the skeleton battle in ‘Jason, and (2) the Medusa encounter in ‘Clash (to name what might be my top two faves). And so when I learned that several of the original (restored) models from those films were on exhibit in northeastern London, I requested to go there with my family for Fathers Day. Results:

Boom! Ole’ stony-gazed, snaky-haired gorgon of yore.

No deadly bow here, but the rattlesnake tail is.

Medusa concept art by Harryhausen; the “bra” was there for American censors but Ray thought it looked wrong and removed it in the final version.

Look out, Jason! Here come the Children of the Hydra! Yep, original (restored) articulated models. Joints are visible. They look ready to kick some Iolcusian butt!

Context of the exhibit- local chap befriended Harryhausen and convinced him to let him restore his models; and so here we are. On with the dinosaurs! (and other palaeo-things)

Gwangi model made in resin; non-poseable but made around time of the “Valley of Gwangi” film to help design the poseable models.

Gwangi climactic scene in church; concept art by Harryhausen.

Other ‘Gwangi characters: “Eohippus” (Hyracotherium), Ornithomimus and boy.

Cowboy lassoing an Ornithomimus as per the movie scene in ‘Gwangi? Yes please. (Harryhausen original)  Jurassic Park had its T. rex lurching out of a forest to grab a Struthiomimus, intentionally mirroring the scene in ‘Gwangi where the titular AllosaurusTyrannosaurus hybrid chomps the Ornithomimus.

Poseable “Eohippus” original- with real fur! Great Dynamation too; very lifelike in the film.

Original Harryhausen concept art of the “Eohippus” show demo.

Suddenly, Ceratosaurus! (from “One Million Years BC”)

Styracosaurus original resin model. (from “One Million Years BC”)

Old school Polacanthus art by Alan Friswell. SPIKEY!

Old school Iguanodon art by Alan Friswell. MUSCLEY!

Panoply of archosaurs by Alan Friswell: pterodactyl, Tenontosaurus (made for the Frame Store special effects company in 2001) and tyrannosaur head (made at age 9).

Pterodactyl made at age 12, so don’t laugh.

Back to the fantastic beasts– original poseable hydra from ‘Jason!

Original Pegasus from ‘Clash! What a seamless blend of fur and feathers.

Original R2, I mean Bubo, from ‘Clash!

I forget the scene (the 1-eyed fates in ‘Clash?) but I like it. Original Harryhausen concept art.

Lunar leader from “First Men in the Moon.” (original)

Non-original (but based thereon) model by Alan Friswell, of nautiloid thingy from “Mysterious Island”.

Fiji mermaid by Alan Friswell.

“Hand of Glory” by Alan Friswell.

Pithecanthropus by Alan Friswell. Very Harryhausen in spirit.

Oddly, but somehow appropriately, there are ?350 year old whale bones on display in the hall next door, with a mysterious history.

WW2 bomb shelter in a “Victory Garden” outside the House. And the house is supposedly haunted. So take care when you visit…

What can I say? I loved it! Almost a religious experience; like seeing holy relics. Awesome in every sense of awesome.

Downside: you cannot grab the precious Dynamation models and play with them hands-on. I wanted to enact a furious Hydra-Gwangi battle. But alas, only in my imagination…

One of my favourite museums in the world, and certainly one of the best natural history museums in the UK, is Cambridge’s Museum of Zoology, AKA “University Museum of Zoology at Cambridge” (UMZC). It is now nearing a lengthy completion of renovations; the old museum exhibits and collections were excellent but needed some big changes along with the re-fabbed “David Attenborough Building” that houses them. As a longtime fan of the exhibits and user of the collection (and microCT scanner), I hurried to see the new museum once it officially opened.

And that makes a great excuse to present a photo-shoot from my visit. This focuses on the “mammal floor” below the entrance- the upper floor(s?) are still being completed and will have the birds, non-avian tetrapods, fish, etc. But the UMZC is strong in mammals and so it is natural for them to feature them in this chock-full-o-specimens display. Less talk, more images. Here we go!

All images can be clicked to mu-zoom in on them.

Stomach-Churning Rating: 3/10; bones and taxidermy and innocuous jars.

The building. The whale skeleton that hung outside for years is now cleaned up and housed right inside; you walk under it as you enter.

Entrance.

First view past the entryway: lots of cool specimens.

View from the walkway down into the ground/basement level from the entry. As specimens-per-unit-volume goes, the UMZC still scores highly and that is GOOD!

Explanation of frog dissection image below.

Gorgeous old frog dissection illustration; such care taken here.

Leeuwenhoek’s flea woodcut; I think from Arcana Naturae Detecta (1695). There is an impressive display of classic natural history books near the entryway.

Dürer/other rhino art image and info.

Darwin was famed for collecting beetles when he should have been studying theology at Cambridge as a youth, and here is some of his collection. Dang.

Darwin’s finches!

Darwin kicked off some of his meticulous work with volumes on barnacles; specimens included here; which helped fuel insights into evolution (e.g. they are “retrograde” crustaceans, not mollusks).

Darwin’s voyage: fish & other preserved specimens.

I think this is a solitaire weka (flightless island bird; see Comment below). I’ve never seen them displayed w/skeleton + taxidermy; it’s effective here.

Eryops cast. More early tetrapods will surely be featured on the upper floor; this one was on the timeline-of-life-on-Earth display.

I LOVE dioramas and this seabird nesting ground display is very evocative, especially now that I’ve visited quite a few such islands.

Mammal introduction; phylogenetic context.

Monotreme glory.

UMZC is well endowed with thylacines and this one is lovely.

“TAZ FEEL NAKED!”

Narwhal above!

Rhinocerotoidea past, present, and fading glory. 😦

Ceratotherium white rhino. The horn is not real; sadly museums (and even zoos) across the world have to worry about theft of such things, given that some people think these horns are magic.

Ceratotherium staring match. You lose.

Ceratotherium stance.

Foot of a Sumatran rhino juxtaposed with a horse’s for Perissodactyla didaction.

A tapir. As a kid, I used to wander around the house pretending to be a tapir but I did not know what noise they’d make so I’d say “tape tape tape!”.

Big Southern Elephant Seal.

Squat little fur seal.

Hippopotamus for the lot of us. (baby included)

Hippo facedown.

Skull of a dwarf Madagascar hippo.

Cave bear and sabretooth cat make an impressive Ice Age demo.

It’s a wombat.

Ain’t no don like a Diprotodon! (also note its modern miniature cousin the wombat, below)

Diprotodon facial.

Diprotodon shoulder: big clavicles bracing that joint region.

Diprotodon knee: even in big marsupials, the “parafibula”/lateral sesamoid of the knee is still generally present. And why it is there/what it does deserves much more study.

Diprotodon hip. I just find this animal’s anatomy fascinating head-to-tail.

Diprotodon front foot. Absolutely freakish.

Diprotodon hind foot. Even weirder.

Your view after having been trampled in a supine position by a Diprotodon. Not a good way to go.

Diprotodon got back.

Elephant seal’s butt continues my series of photos of big animals’ bottoms.

Asian elephant’s butt view.

African elephant butt.

Sectioned elephant skull to show pneumatic resonating chambers.

Paenungulates: hyraxes, Sirenia, elephants & kin (evolutionary demo).

AND MY HYRAX!
Sorry. Had to.

Megatherium side view.

Megatherium. Yeah!

Megatherium hindlegs fascinate me. Well-heeled.

Tamandua duo.

Silky anteater; wonderful.

Armadillos.

Anteaters round out a fab display on Xenarthra.

The UMZC has everything from aardvarks to zebus. Here, conceptualized with other Afrotheria.

Golden moles: the more I read about them, the more they fascinate me.

We can all use some more solenodons in our lives!

Example of the phylogenetic context used throughout exhibits.

If you’ve got a good Okapi taxidermy, you’d better use it.

It’s a giraffe. Did you guess right?

Gerenuk showing off its bipedal capacity.

Warthogs have an inner beauty.

Pangolin. Glad to see it back on exhibit.

Nice little brown bear.

Double-barrelled shot of hyenas.

Colugo!

Nice to see some Scandentia featured.

My brain says this is a springhare (Pedetes) so I am going with what my brain says and anyway I really like this display.

When I saw this I thought, “That’s a nice… rodent thingy.” And so “rodent thing” it shall be labelled here. Enjoy the rodent thingy. Some serious taxidermy-fu in action.

Moonrats– now there’s something you seldom see a full display of. Well done!

That’s part I of this sneak peek at the evolving exhibits- I will put up a part II once the upper floor exhibits open. I highly encourage a visit!

For Mike: gimlet

As a person who has transitioned from the “simple life” (haha) of a grad student to postdoc to younger and then more experienced faculty member in academia/science, I constantly ponder how I spend my time. This is more so true lately, thanks to social media keeping me aware of how others spend their time (e.g. conversations about overwork and unrealistic expectations in academia/science), and thanks to my own experiences managing a moderate-to-large-sized group of 5-15ish scientists in the past ~10 years. I’ve had to learn to juggle a lot more than I did before and my life also has changed a lot (family, health, etc), some of which I’ve blogged about here before. Some of that excessive juggling is why there haven’t been so many blog posts here recently!

But today I want to turn the lens on the post’s title topic. What does a “typical” weekday in my life look like, with a focus on the academic/science aspects? There is no such “typical” ideal; every day is very different, but a Platonic abstraction will be heuristic. Let the clock tell the tale…

Stomach-Churning Rating: opinions may vary but I say it’s 0/10 (no gory photos).

0600-0700 I wake up and rush for the 2 big mugs of coffee that get and keep me moving, overcoming some huge side effects from medications I’m on. I feed the cats and check my email whilst having my coffee (and cereal + yoghurt). I deal with several simple messages from USA colleagues, or UK colleagues up late. Emails requiring more mindpower are saved for later. I tweet/retweet a little while skimming social media.

Nectar of the gods!

0730-0900 After shower etc. I begin my commute. 90 mins walk-train-train-walk (if no delays) and I can fit in another 60 mins or so of emails and some higher-functioning work (e.g. writing; editing papers; catching up on literature) on the train if I am feeling up for it. If I’m still too sluggish I listen to a (not-strictly-science but intellectual) podcast; e.g. RadioLab or Invisibilia; or (worst case) some rockin’ music.

0900-1000 Catching up on things in my office, with a few more emails, some organizing, quick chats with people around my office, and my day takes shape as I near my peak level of energy (and busy-ness).

1000-1200 Full steam ahead! I try to schedule my most demanding meetings to give them my full attention, or do my most challenging work if on my own.

1200-1230 John infamously gets hungry every ~5 hours and there is no stalling his need for fuel. Off to the campus restaurant he goes, for a hot meal and a little quiet time away from his office, to think/chat.

1230-1300 I like to leave this time as very flexible “me time”, whether spent on social media or whatever. I just do what suits me, maybe tidying up loose ends with smaller tasks, or just chilling (relatively) in contemplation.

1300-1400 A maybe less demanding meeting or a seminar (or a committee); in the latter case my powerful post-prandial somnolence becomes a battle now (and I don’t do caffeine >0800ish! Too sensitive). But I keep pushing on, and stuff gets done.

1400-1500 Another research-type meeting or data collection session, or writing, to fill some final, very valuable, on-campus time.

1500 Run for the train home, trying to stealthily escape campus without having any impromptu meetings that make me miss my train. My work day is not over but the commute is tiring so 6 hrs on campus and a bit more before and after are plenty!

1515-1645 Train ride and a bit of work where I feel able (50% of the time?).

1700-1800 Some catch-up emails (e.g. USA colleagues are waking up by now) and catch-up with family; juggling a lot. My activities vary a lot here: I may be inspired (even catching a second wind) to get some final work done or I may be totally wiped out and need a break. I listen to what my body tells me and also try to ensure I give myself time for non-work from here on.

1800-2100 Quality non-work time.

2100-2200  A bit of non-science reading before I fall asleep.

2200-0600 I need my 8 hrs sleep or I am a slow(er) grumpy John.

I’ve listed a “typical” day for non-teaching weeks. Currently my teaching load isn’t large by any measure, nor do I have many committee duties, and I am paid by my DAWNDINOS grant to spend 70% of my time (thru 2021) on that one project. So other than my October-November teaching I am mainly doing that 70% DAWNDINOS work, in various forms, plus a 30% that is some kind of science: a HUGE array of collaborations, some still stretching back to circa 2001 and still alive, some social media of course (although less these days than in ~2011-2012’s heyday, you may notice), and a potpourri of “other stuff”.

That “other” category is vast — travel to far-off places is a big time-sink lately, such as with 4 trips to the USA’s west coast in the past 4 months for seminars and conferences (although much of that involved DAWNDINOS presentations too). I am glad it’s all done, much as it was valuable science communication and meetings with friends/colleagues. Emails of sundry sorts fall into that “other” category too: I am not sure how many emails per day I field but I am the type of person that likes to handle a lot via email. Thereby I have a written record (my memory is patchy at times even though it can be excellent) that helps me organize my thoughts and actions. Maybe it’s 50 emails/day? Plus another 50 emails of fake conference/journal spam that seem to take more time deleting than they should (hello, spam filter)? Hosting visitors, talking on the phone/Skype with science writers, and certainly doing journal editorial/peer review duties are other big chunks. And so on; I won’t list it as most of it is normal academic life stuff. (Aside from the occasional elephant post-mortem)

Now, I got into academic life for what I feel are very good reasons, for me. A bit of context: I started working as a newspaper delivery boy at age 12, and continued that until I was maybe 15, then did odd jobs such as washing biochemistry dishes in my dad’s lab or fast food cashier/restaurant busboy & dishwasher until college. Then I kept up some intermittent part-time jobs like selling music CDs at Sam Goody, mixing margaritas as a “blender jockey” at Chi-Chi’s Mexican restaurant or tending snails at a marine ecology lab (thanks, Dianna Padilla!) until grad school. The point is, my parents had the wisdom to inculcate a work ethic into me, and that was VERY good, although I also got a strong taste of what it was like to work in a typical business, punching the clock in and out each day. And I HATED that clock-punching. It still provokes a deep visceral reaction from me. (Aside: ironically, that generous DAWNDINOS grant requires me to log my daily hours, and I hate that too but it must be done!)

In Sarasota, Florida where we spent winters with grandparents and I gleefully chased Anolis lizards (one blurry one here, I promise!).

To tie the story up, academic life attracted me (and I saw enough from my dad’s life as a professor to know) because it offered an escape from that punch-clock, 9-to-5 Monday-Friday life. The 9-to-5 strict schedule is just not for me, although I have plenty of respect those for whom it is; the world needs all kinds. I need flexibility; I need to be able to do science when Athena’s muse strikes me, not feeling chained to a rigid schedule and suffocating bookkeeping of how time is spent. In reality, in academia/science I feel now that it is impossible for me to realistically quantify how much time I spend on particular things – I may get a good idea while on the toilet, and that counts as science time doesn’t it? I am probably juggling a dozen things at once in my mind and efforts; work/other life/bullshit; at any one time, so partitioning my time is subjective nonsense. I prefer to be judged (when I must be judged) on what I do and its quality, and to be trusted to do this right by some “fair” standard rather than hours. To me, that’s what academia/science should be… (current reality be damned)

I blame the 80s.

That brings me to, how does a weekend look? In grad school I didn’t mind devoting some of my weekends – and plenty of late evenings – to work. Now, especially with a family, I do mind it. Living in Europe has helped me appreciate that quality-of-life mentality as well. It can still be a struggle within me, as I love science and sometimes I just want to do it; it may not matter if it is 6am on a Tuesday, 1pm on a Thursday or 7pm on a Saturday. Often I say “no” and don’t, and that can feel good, but sometimes I let myself enjoy after-hours work, because I live for enjoyment in all its forms in my life. That is a privileged position to be in and I do not forget that privilege. However, I’ve worked since 1989 to get here, so 29+ years of university life has to have been for some non-disposable purpose in my life. I’ve posted before about work-life integration and how I don’t personally recognize a rigid divide between these in my life, but with 24 hours in a day there is a real zero-sum game at play, so I prioritize what I do (or go with the moment).

In non-work mode: Reggie Regent (I’m the lion on the left; not the dog, who was beloved Daisy); high school mascot. A very sweaty one in that suit!

One failure I am working on is to return to fitting in ~2 gym workouts/week into my weekday schedule; that was good when I was doing it a couple of years ago. I have no great excuses for that. Nor would I rely on the “too busy” excuse for anything above — I find the “cult of busy” in academia to be tedious and repugnant (the post linked there is mainly about PhD students but at the faculty academic level such genitalia-sizing-up talk is rife). We all do what we can with our limited time, yet our life-goals are probably not identical, and we probably don’t understand what others do with their time or what constraints they work under.

Dealing with encroaching age and disability has thrown new challenges into my time-budgeting that I am still grappling with. I may want to work (or even need to, beyond the level of overcommitment I’m already in) but sometimes I simply do not have the energy. I don’t give myself guilt and grief for this if I can help it, while I expect that once I do have more energy I’ll devote it appropriately. I respect my limits, much as I confess I still don’t understand them.

As a lifelong learner, I am still learning how to live my life, one day at a time. Everyone lives their life differently. My life now is lived so incredibly differently from how I lived it 20 years ago as a young grad student that I can have a hard time recognizing myself in that scared, scarred, lost, naïve yet still very excited man.

One day that young grad student went into San Francisco, bought a huge teddy bear, and brought it home to cuddle with because he felt so alone. A blues musician on the street saw him carrying that bear and improvised a song mocking him, and he didn’t mind because it was the truth that was captured in that parody, and he was a student of the truth. It was a dark period in that man’s life—a void that was filled with work.

“How, then, can we fail to take the importance of factuality and reality seriously? How can we fail to care about truth? We cannot.”

But now my daughter has inherited that bear and it was worth every dime, every lonely tear, and every hour worked to become the person I am; the only person I can be at this moment, flawed yet ever in flux. Tomorrow will be another day and I will be grateful for those new hours, awake to their prospects and alert to their tribulations.

That was a condensed day in my scientific life and some backstory to it. Thanks for taking your time to read it.

We’ve been through a lot together.

Darwin the Human

A personal story here for Darwin Day 2018. I knew about as much about Charles Robert Darwin as any typical science-interested student when I was growing up. But eventually I had the good fortune of taking a history of science class at the University of Wisconsin as an undergrad, and it inspired me with the story of Darwin as a human being, not just some clever scientist with a long argument that changed the world.

Stomach-Churning Rating: 0/10 unless you have Darwin’s gut-wrenching problems.

I devoured Desmond & Moore’s amazing biography of Darwin “the tormented evolutionist”, which was the transformative event for me. At the time I was experiencing the beginnings of some health problems that didn’t seem that far from problems Darwin suffered for much of his life, and then, as I read more about his life, I saw more features of this man that brought him vividly to life. I still think about those traits and how some parallel my life in certain ways (not that I am in any way a giant of science like him!!). And so this blog post was born, thusly:

I’m writing this post early on Darwin Day and entirely from memory, rather than doing my usual research into the post while I go; to keep the post more personal and less academic (e.g. just quick Wikipedia links below). I feel connected to Darwin’s life experience because, like him, I wandered about as a student, unsure about my direction in life and causing my parents some consternation early on. He tried medical school (Edinburgh; too bloody) and theology (Cambridge; faith just was not his thing) but found hunting for beetles on the heaths more exciting. In high school I played with ideas such as Hollywood screen-writing (too risky), radio DJ (I had no skills) and truant or criminal (I hung out with some shady characters even though I still had some morals; despite transgressions and convictions).

I then took a standardized “what is your best career fit?” test in biology class which conclusively told me that biology was best for me as a career; and that rang true. I’d always loved nature and so that was the idea I had when I went to undergrad. I signed up for the wrong college (Agriculture & Life Sciences, not Letters & Science; confusing divisions!) at the UW. I got some early research experience in that first college: I tried my hand at raising colonies of Indian mealmoths (Plodia interpunctella; I can still identify them!) and their parasitoid wasps. At that same agricultural lab I got to do my own experiments in a basement wind tunnel over my summer holiday, in which I released those pesky moths to fly down the tunnel toward various kinds of pheromone-based lures, finding that one kind seemed to work best. But I didn’t like that and frankly found agricultural science boring, for me. We didn’t connect, nor did some other lab experiences I had. But I grew from them and still value them (and respect the science and people involved) very much.

I took Evolution and also Functional Morphology courses, didn’t do great (I was young for the classes), and then finally took that history class—boom! Aha, scientists can be human! Not just hypothesis-robots! Darwin was a man of great privilege, having his estate and wealth handed down from his funky grandpa Erasmus and stern father Robert. But, in addition to his meanderings that eventually forced him (via his father’s impatient urgings) to become the Beagle’s naturalist for a five year voyage, he suffered in quite human ways throughout much of his life. The greater trials commenced during that voyage, with still-mysterious health problems and the fractious relationship with eccentric Captain Fitzroy. They continued with his marriage to cousin Emma Wedgwood (yes, of that pottery-famed lineage) in which they lost four of ten children at young ages (most critically, beloved Annie at 10 years old) and in which they struggled with Darwin’s diminishing faith and Emma’s stalwart beliefs.

Finally, Darwin struggled famously with his “big book” for >20 years, afraid of its impact and its reception, and of its need to have a watertight, evidence-based argument from many perspectives, with his hand forced by Alfred Russel Wallace’s converging ideas. Along the way, with his health and family problems, he had to contend with his mentors’ and peers’ reactions to his ideas—although one could call the acceptance of much of his main arguments to be a “happy ending” (the post-mortem eclipse of Darwinism, and its eventual resurrection + syntheses, aside). These trials that Darwin faced as a human are all relatable, and the more one learns about him the more complex, flawed, emotional and yes, tormented he becomes. He can be both a hero and a tragic figure or a cautionary tale.

When I get the chance, I like to teach students about this human side of Darwin. It is a way into the heart of the science, to show a person’s journey along with the wonder of discovery, and how such a journey is not necessarily a simple or even joyful one. I can feel the many facets of Darwin in my own life—the intensely curious, peripatetic, enthusiastic young man who loved experiencing nature in all its raw forms, the chronically suffering disabled person who sometimes could not enjoy the work or other aspects of life that he treasured, the family man who loved time at home, the explorer who treasured roaming the local heath or far-flung foreign terrain, the meticulous scientist who exhaustively gathered tiny bits of data in isolated studies to slowly build toward grander ideas, and much more.

But Darwin is a different human, too. We live in such different times, when there the world of science is far larger but the world feels far smaller, more interconnected. Naturalists today are not simply landed noblemen who can play with science in their luxurious spare time, nor do they work alone at their pursuits. Anyone can be a scientist, and a career scientist can, if they are fortunate and skilled enough, assemble their own laboratory in which they lead a team to tackle their big questions that captivate them. The individual questions in science tend to be smaller (more incremental and specialized) today, yet can overall (across career(s)) be bigger because we can tackle -and have tackled- some of the bigger ones; Darwin’s big questions being among the giant ideas we are now poised upon.

It’s not all about science, though. Darwin’s story, which I think about so often, reminds me of how we all struggle in our lives and amidst the joy of discovery in everyday life there can be considerable suffering and regret. It is a bittersweet story; an ever-so-human story. And today is a good day to reflect on that, and to celebrate life while we lament what has been lost.

Jumbo Time

Back in November 2016 I got an exciting email from colleague Dr. Richard Thomas, who was building a team of experts for a proposed documentary on Jumbo the elephant; the famed proboscidean of the Victorian era (and arguably most famous elephant of all time, first international celebrity animal, etc.). I knew him from social media and from our mutual interests in chicken anatomy and evolution. And that exciting email, for once, worked out! Over coming months I chatted with the film producers and they could see a place for me in the programme, contributing my expertise in elephant (postcranial) anatomy, locomotion, health/welfare etc. Lo and behold, in May 2017 I met Sir David Attenborough at Heathrow and we flew out to New York City to film with the skeleton at the American Museum of Natural History. And to cap it off, I got to meet another childhood science communication hero: Professor David Suzuki of CBC’s “The Nature of Things“– my adrenaline levels were sky high!

Brooklyn neighborhood by our hotel. Lots to do!

The show has aired in the UK and is coming very soon to Canada and the world (details below). Here’s my part of the story.

Stomach-Churning Rating: 3/10– bad bones but no blood.

We filmed from 15-19 May 2017 at the AMNH’s warehouse of mammalian skeletal remains, which is housed deep in the Brooklyn Army Terminal; a picturesque site in and of itself. And it is a site with a lot of history— WWI and II, Elvis and more.

It was a hectic week of the usual documentary stuff: repeat the same lines and motions again and again from different angles and with different paces and intonations (I cannot help in these cases but think about the Simpsons “Fallout Boy” episode), from ~9am-5pm, with plenty of downtime watching setup or other bits being filmed. I’m used to all that. But having the time to peer around the collection and chat to Richard and colleague Dr. Holly Miller (handling the tissue isotopes side of the story) about Jumbo’s skeleton was a lot of fun during downtime and filming itself. Not to mention the utter joy of studying one of the most famous museum specimens ever, and an animal widely held to be one of the largest of its kind, with much mystery surrounding its history despite its fame. (Wikipedia does a fair job of summarizing some of this)

Here are some photos to tell the story:

That’s the setup. I’ve done ~15 other documentary episodes/shows but this was like nothing else– simply an awesome experience.

Now the delivery: we set to studying those bones. We’d seen photos before, and Henry Fairfield Osborn had illustrated the specimen as his type of “Elephas africanus rothschildi” (Sudanese elephant; no longer valid but those were different times– it’s now just a nicely preserved Loxodonta africana africana), so we knew some of what to expect.

Looking at Osborn’s classic monograph. Oddly he didn’t address the GLARING MASSIVE PROBLEMS WITH THE TEETH!

Skull with terrible tooth pathologies– and let’s play spot Mumbo, my daughter’s toy elephant! He might even appear in some TV footage!

We had noted some serious issues with some bones (pathologies). I won’t spoil the message here but will show some images. I know some experts have voiced issues with how the tooth pathologies/growth were explained in some footage but I can’t address that here; it’s not my expertise. The important point to me is that the teeth are incredibly messed up and that can easily be linked to bad diet and other management/health issues, as the documentary explains.

Jumbo’s torso in left side view. Glorious preservation.

Right forelimb, showing that the “growth plates” (epiphyses”) were not all fused, consistent with Jumbo still growing– as expected for an African male elephant in his 20’s.

Right elbow with some pathologies consistent with degenerative joint disease.

Surprisingly, Jumbo’s feet were not in nasty condition in terms of pathologies. I’d expected to see that. They’d been painted and drilled for mounting, but were not riddled with arthritic changes that I could see.

Strange bony plaque on the left pelvis (hip) region; something I’d never seen before in any elephant (and I’ve seen many). Why? The programme offers a reasonable explanation.

Jumbo’s right hip, with bad erosion of the bone and thus presumably the overlying cartilage. Ouch!

Strange extra prong on one right rib in Jumbo- we didn’t figure that out. It could conceivably be natural variation.

So, poor Jumbo suffered some jumbo-sized problems, and in complex ways. That’s just scratching the surface of what his skeleton tells us, and there’s plenty more in the show plus plenty more we can say later– there’s real science that came out of this programme! I was surprised to find how little had been stated anywhere in the scientific literature about Jumbo’s pathologies.

Sad as Jumbo’s skeletal story is, the broader story of his life and death is sadder still. For purposes of time I don’t think any of the three versions of the show will get to delve into how Jumbo’s mother may have been slashed to death by a broadsword, as the story below describes was the ancient practice:

I’d hate to be “so pestered by a popinjay”, too.

Adding insult to injury, we can reflect on how Jumbo was taken from the Sudan to the east (across the Suez), then on boat to Italy and then overground to Paris, where he lived for a little while until the zoological garden sold him to London. Luckily Jumbo avoided becoming a meal to starving Parisians during the Prussian siege of 1870-1. So he did not become elephant consommé like some of his co-captives did. The more one learns about Jumbo’s life and the life of elephants in captivity in the 1800s, the more harrowing the tale becomes.

Jumbo is THE celebrity elephant. His name has come to mean ‘big’ and ‘bombastic’, from applications to jumbo jets to hot dogs and other (darkly ironic) forms of consumption and extravagance. He has had a jumbo effect on Western culture, but also symbolizes the complex human-elephant relationship, such as the inspiration for “Dumbo’s” own sad story. We love elephants but our fascination with them can also be their undoing, such as poaching for the ivory trade or mistreatment in captivity. Jumbo’s story writ large is also the story of elephants, and our story to learn from. If anything comes out of my participation in the Jumbo documentary for the public’s benefit, I hope it is increased empathy for how we interact with elephants. They are like us in many ways (maybe over-emphasized with anthropomorphism in many accounts), but also unlike us (maybe even unfathomable) in not only their size and anatomy but also in aspects of their prodigious intellect, emotions and social structure. Elephants aren’t just jumbo spectacles. They are jumbo responsibilities for humans now that we dominate the planet so much.

Want to catch a version of the Jumbo show? I’ll try to keep this list up to date:

An epiphysean Sispyhean task today: solve this mystery that has been bothering me for >15 years. It’s about bird knees. Read on.

Stomach-Churning Rating: 1/10- bones and brief words. Nothing to worry about.

Here is an ostrich. I was interviewing undergrads the other day and looked up to see it, then thought something like: “Oh yeah, that little bit of bone really bothers me. I cannot figure it out.” What little bit of bone?

Right leg, side view, ostrich…

This little bit of bone. Zooming in on that ostrich’s knee:

Who am I? (femur above; tibiotarsus below; “PTE” is the crest of bone with the white arrow on it)

The little bit of bone is not talked about much in the scientific literature on bird knees. But we know it’s there and it is part of the composite bone called the tibiotarsus (ancestral tibia, this bit of bone, and the proximal tarsal [ankle] bones on the other end; the astragalus and calcaneum of earlier dinosaurs).

What is it? We call it something like the proximal tibial epiphysis (PTE for short, here). An epiphysis is an end of a bone that fuses up with the shaft during growth, around the time of skeletal maturity; ultimately ending longitudinal (length-wise) growth of that bone. Mammals almost ubiquitously have them. So do lizards and tuataras. And some fossil relatives. Not much else– except birds, in this particular region (the two ends of the tibiotarsus; also in the foot region; the tarsometatarsus; which also has its share of mysteries such as the hypotarsus; I won’t go there today). You can see the PTE in mostly cartilaginous form if you take apart a chicken drumstick.

This PTE, like other well-behaving epiphyses, fuses with the tibiotarsus in mature birds, forming one bone. But the young ostrich’s knee above shows the PTE nicely; and other living birds show more or less the same thing.

It begs for explanations. I’ve talked about it in a few of my papers. But I’ve always punted on what it really means– does it have anything to do with the patella (they appear at similar times in evolution; we know that much, roughly)? Where does it come from, developmentally? (we sort of know that but more work is needed in different species and in high resolution) When did it evolve? What does it tell us? Why is it there in living birds and almost no other extinct birds/other dinosaurs? Does it have anything to do with why birds, during their evolution, seem to gradually increase the fusion of skeletal elements or ossify new ones (tendons, kneecaps, etc)? Why here and not in the femur or several other long bones of birds? How much do these PTEs vary between (or within) bird species?

This is the challenge in the post’s title. I present to you: solve this puzzle. Developmentally, biomechanically, evolutionarily, genetically, whatever– why does this PTE happen? There are hints– e.g. this paper proposes why growth rates of long bones favour the formation of “secondary centres of ossification” like this. But I’m unable to satisfy myself with any solutions I can find. Maybe you can complete The Bird Knee Challenge?

Have a go at it in the Comments below! There are plenty of papers or even a grant or something involved in sorting out this single mystery; one of the many basic mysteries about animal anatomy.
