Farish A. Jenkins, Jr., 1940-2012

by Greg Mayer

Farish A. Jenkins, Jr., Curator of Vertebrate Paleontology and Alexander Agassiz Professor in the Museum of Comparative Zoology at Harvard University, died on November 11, 2012. Farish made major contributions to vertebrate paleontology, functional morphology, and evolutionary biology. He had been ill with cancer for some time, but had continued to work productively, and his death came quickly following a recent reverse. (See update below.)

Although Farish published on many subjects, the part of his work likely to be of most interest to WEIT readers is that on transitional forms. Farish worked on three great transformations in the history of tetrapods, including two that have become classic case studies in the origin of higher taxa. First, he worked on the origin of mammals, often in collaboration with his  MCZ colleague, A.W. “Fuzz” Crompton. That the ancestors of mammals were to be sought among a particular group of fossil reptiles known as synapsids had been known since the 19th century. What Farish, Fuzz, and many colleagues helped to show was how this transition occurred, and how the bones of the reptilian jaw joint of synapsids moved in to the middle ear of mammals to become ear ossicles, while a new jaw joint, the mammalian jaw joint, evolved. It is a favorite tactic of creationists, even today, to ask how possibly could the jaw of a reptile come unhinged, and a new joint develop, with the reptile bones passing into the ear? Well, the answer is, we know exactly how they did it, because we have the fossils- read Crompton and Jenkins, and look at the pictures!  (For the latest on mammalian ear evolution, see this paper by Luo Zhe Xi.)

Farish was one of the triumvirate who, along with Neil Shubin and Ted Daeschler, described Tiktaalik, the fish-tetrapod intermediate from Arctic Canada that made the front pages of newspapers around the world when it’s discovery was publicly announced in 2006. Neil and Ted got most of the media appearances, but it was Farish who was the old hand at arctic paleontological exploration (in the video below, look for Farish at 1:45). Although describing Tiktaalik taxonomically and morphologically was but a small part of his copious output, Farish may be best remembered for this work.

Most recently, Farish and colleagues completed a monographic account of Eocaecilia, a caecilian with limbs (which they had named and briefly described years earlier). Caecilians (not to be confused with the edible variety) are a group of tropical amphibians which today lack limbs, and Eocaecilia is a form that is transitional from fully-limbed ancestors to the modern condition.

Both Jerry and I knew Farish from our days at the MCZ. I last saw him on a visit a year or two ago, after he was diagnosed with cancer, but he was his usual voluble self; Jerry saw him at the MCZ just a few months ago. Always impeccably dressed and charming, he had the demeanor of what I imagine a retired officer of the Royal Horse Guards would be like. He helped organize and lead a superb graduate course on vertebrate paleontology (I cannot recall now whether I enrolled or just attended) in the comfortable environs of the Romer Library, named for one of his distinguished predecessors at the MCZ, Alfred Sherwood Romer. I do recall stories of Arctic fossil hunting, with high powered rifles a necessity, as one man stood guard for polar bears, while others peered at the rocks. In addition to his teaching duties in the Faculty of Arts and Sciences, Farish taught human anatomy at the medical school. His comparative and evolutionary approach was not only appreciated by medical students, but also provided an opportunity for vertebrate morphology graduate students, by either taking the course or assisting in its teaching (or both), to gain the experience and background in human anatomy that would allow them to go on and train generations of physicians, as well as commanding the much higher salaries found in medical school anatomy departments. The Nature News Blog has some nice recollections of Farish by Hopi Hoekstra, the MCZ’s curator of mammals. The science writer Hilary Rosner has posted an endearing reminiscence of her encounters with Farish, along with a number of fine photographs, at her blog, Tooth & ClawAs another MCZ colleague put it to me earlier today, “His lectures were legendary…He was a scholar and a gentleman, and truly one of kind.”

A symposium in Farish’s honor, Great Transformations, was held last June. Like Ernst Mayr, also of the MCZ, who got to attend and speak at his 100th birthday symposium, Farish too was able to attend and speak at this gathering to celebrate his achievements. I understand there is a festschrift of the contributions in the works, but unfortunately Farish will now not see it.

Update. More accounts and reminiscences well worth reading have appeared in the Harvard Gazette, Boston Globe, and at Postcardsfrom Farish.

    Nice post, Greg! I’m curious, though, why the reporters didn’t interview either Fuzz Crompton or Neil Shubin, both of whom worked directly with Farish, rather than just Hopi Hoekstra. Do you think this was a rush job?

      I too would have gone first to Fuzz and Neil, so it may be the case that Hopi happened to be who they could get hold of in time for posting. Neil has now commented here at WEIT, and both he and Fuzz were interviewed by the Boston Globe for their fine obituary. The Globe also interviewed Steve Gatesy, another MCZ alum, who was part of the Arctic field team and found the first Tiktaalik specimen. An interesting item from the Globe is that Farish had been a captain in the Marines, which I had not known; my likening him to a retired officer of the Horse Guards was thus more nearly true than I had thought.

    Great job, Greg.

    Tiktaalik would never have been found without Farish. He had the “arctic toolkit” that allowed us to transduce a good idea to a real field project. Also, his intellectual contributions were immeasurable.

    The other notion is that, despite the Arctic project being a real struggle, with six years/four seasons of very hard work and not much to show for ourselves, Farish kept us laughing. Fieldwork, whether successful or not, was always a joy with him. We do our science for what it tells us of the world and, often for its intellectual beauty. But we also do it also because it can be truly fun. Farish made it so for me.

      Neil–

      Thanks for this– your comments here are very welcome and enlightening. I’m sure more will be said by you and his other colleagues and students in the coming days. Farish will be missed.

    Reading this and Hilary Rosner’s post have made me quite sad at the loss of a person I never met. Thank you for sharing your memories of him with us.

    Tremendous post, honoring a tremendous man. He was my professor at Harvard and one of the best people I have ever met. No matter the interaction, he always made you feel like he was giving you all of his personal attention and care. He will be missed! I’ve started another blog for people to share their thoughts (and hopefully some of the many postcards I’m sure he’s sent over the years from Ellesmere!) at:

    Tiktaalik…now that’s a legacy to leave behind. And not as a one-hit wonder, either!

    Somehow, I rather doubt I’ll come close to his score when my own game is over. Then again, so few of us will….

      As Greg showed, the amazing thing was that Jenkins legacy was much, much more than Tiktaalik. He leaves generations of Harvard College, HST, and Graduate Student advisees, as well as many an assistant professor who are the better for knowing him. He, with Fuzz Crompton, defined an integrative approach to link neontological and paleontological data in evolutionary analysis. And, finally he is the discoverer of many an important fossil: Prosilarius, Haramyavia, Eocaecilia, Dinnetherium, and so on. His legacy was secure even if Tiktaalik remained laying in the Arctic bedrock.

        Yes, exactly — that’s what I meant by the “not a one-hit wonder.” Kinda like remembering the Beatles for Sgt. Pepper or Stravinsky for The Rite of Spring or Beethoven for his fifth symphony.

    Thanks for this great tribute to Farish, Greg. I hope he is remembered as much for being a superb and unabashed naturalist as for any of his many other terrific but typically undersung accomplishments. Farish’s anatomical renderings, a la Sidewalk Sam but then some, will always be one of my most enduring and endearing remembrances of the old MCZ. I think we should breathe new life into the tradition that he so well embodied, by holding literal chalk talks in his honor and memory. Of course Karel was also a big chalker, as are so many others among our greats. Let’s not forget to nourish our roots as we water the leaves and branches of our profession.
