Monkey Bones

001

Deep within the greenness of the rainforest, a very long time ago, lived a group of chimpanzees. They travelled through the trees and climbed down from branches to forage on the forest floor. On the hottest days the females lay on mossy rocks beside narrow streams to feel the cool spray of the water. Crouched high above the rest of the group, a baby chimpanzee watched his mother and aunts, and looked beyond his family to the darkness between the trees. The sound of a cracking twig and the rustle of leaves attracted his attention and, unnoticed by his mother, he clambered across the rocks and disappeared into the trees never to be seen again.

That is, until a small skeleton of a baby chimpanzee was crated from the Horniman Museum to the Royal College of Physicians (RCP) in London. Standing erect and staring out behind a glass case on the marble hall, this little chimp led an ‘exploration of ideas’ at the evening lectures ‘A race of mankind’: Chimpanzees and anatomy at the RCP.

I went along to the talks on Monday 24 June to see the most recent unusual monkey from the Horniman Museum on display at the RCP.

‘Some of you might remember a monkey who was here last year who was so popular that we couldn’t resist getting another,’ said Beth Wilkey, assistant curator at the RCP. She was, of course, referring to another weird monkey that I blogged about: Monkey-fish.

‘You may think: what has a monkey and physicians got in common?’ Beth introduced the evening’s speakers, Dr Bernard Wood of the George Washington University and the Smithsonian Institution, and Paolo Viscardi of the Horniman Museum, who would tell us.

‘When physicians were polymaths’

Dr Bernard Wood traced the history of comparative anatomy (the study of anatomy between species) and molecular biology by pioneering scientists, and fellows of the RCP, who studied the close relationships between modern humans and primates.

Starting with Charles Darwin’s Tree of Life that shows how all species on Earth have evolved from common ancestors and are closely related, Bernard pointed to the tips of the tree and its neighbouring branches: ‘All the animals that are alive today are on the top branches, and the lower branches show all the species that have existed and are now extinct.’ Humans belong on the same branch of the tree as apes and chimpanzees, our closest living relatives, and we share a common ancestor who lived around 8 million years ago.

From the origins of mankind, we were taken back to a time when our understanding of our place in nature was a blank canvas waiting to be painted by minds burning with scientific curiosity. Such a mind was RCP fellow Edward Tyson (1651–1708), widely considered to be the founder of modern comparative anatomy. A fellow of the then College of Physicians, Tyson was an anatomy reader at Surgeons’ Hall – and maybe not a physician at all: ‘He spent most of his time cutting for surgery, so if it looks like a duck and quacks like a duck, then this guy’s a surgeon,’ said Bernard.

There was, frankly, nothing Tyson wouldn’t dissect, Bernard commented. But it was his dissection of a chimpanzee in 1698 which led him to write Orang-Outang, sive Homo Sylvestris: or, the Anatomy of a Pygmie Compared with that of a Monkey, an Ape, and a Man (catchy title), the book that was the common link between the skeleton on loan and the evening’s lectures. Tyson’s exploration of the anatomy of the chimpanzee, particularly the brain, resulted in his conclusion that humans and chimpanzees were closely related.

The exploration of the similarities in anatomy between humans and apes continued with RCP fellow Emil Zuckerkandl (1849–1910), a Hungarian-Austrian anatomist who made significant contributions to the field of morphology (the study of the structural features of organisms such as bone, organs, muscle and tissue). ‘Although dissection seems old fashioned and low-tech, it is still going on,’ said Bernard on why dissection was crucial to our understanding of the human body and of evolution.

With a better understanding of what monkeys and physicians have in common, we moved on from the discussion of physicians as polymaths – exploring our place in the great scheme of things – to another perspective of the evening’s fascinating specimen.

‘The monkey tree puzzle’

‘He’s a rather nice little specimen,’ said Paolo Viscardi of the Horniman Museum, whose talk also opened with Darwin’s Tree of Life, or ‘the monkey tree puzzle’.

Paolo traced the paths of curious explorers of the past who collected and brought back strange and wonderful objects from different parts of the world. Their discoveries and accounts of what they had seen were collected together as ‘cabinets of curiosities’, which would eventually become vast repositories of our knowledge of natural history – or museums.

An illustration of Ole Worm’s cabinet of curiosities showed that when you have a lot of stuff you need a way of grouping and storing it. ‘I say this from bitter experience of working in a museum,’ said Paolo. These early collectors’ attempts at categorising their collections could be seen as steps towards modern taxonomy.

It wasn’t until Carl Linnaeus (1707–1778), Swedish botanist, physician, zoologist and reputed father of modern taxonomy, that we looked at ways of logically categorising species: ‘He grouped humans with apes and sloths!’ Paolo explained how we continue to group things – building bigger and bigger categories by looking for similar characteristics through comparative anatomy.

Paolo’s exploration of comparative anatomy and theories of evolution led to the famous evolution debate at Oxford University Museum in 1860 where eminent scientists and philosophers argued about Darwin’s recently published On the Origin of the Species. There was a heated exchange between two scientists Samuel Wilberforce and Thomas Henry Huxley: ‘Wilberforce asked Huxley whether it was through his grandfather or his grandmother that he was descended from apes.’

These various ideas on the origin of mankind and of our close relationship with apes has captured our imagination for centuries from King Kong, to Tarzan, to chimpanzees dressed up as humans. Paolo finished on the star of the show, the unusual baby chimpanzee skeleton standing on the marble hall about whose origins ‘we don’t know very much – yet!’ and who will be investigated closely.

‘A race of mankind’: Chimpanzees and anatomy at the RCP

The chimpanzee skeleton is on temporary display at the RCP as part of the ‘Object in Focus’ loan scheme from the Horniman Museum and alongside other rare objects from the RCP’s collection including rare books and a portrait of Tyson.

  1. Great venture off-bee-piste. *digresses* Horniman’s tea (hence, the museum) used to have amazing (to a child) wildlife cards to collect… and a book to stick them in (flour-paste). But then you couldn’t read the backs. Anyone want an almost complete collection? Didn’t think so!

    • The chimpanzee skeleton is yet to be fully investigated from what I understand, but it could have happened that way… Horniman and RCP do have a knack for displaying unique and fascinating exhibits!

  2. I really enjoy living in the country but when you post about the things you get up to near London I do have a twinge of regret. At least you take advantage of your opportunities and what’s better – share them with us!

    • My dream is to live in the country – you are living my dream *sigh*

      Next time you’re in London, do check out these wonderful museums and gardens with your family. They are just lovely! x

      • The RCP has an annual Christmas lecture aimed at young people. This year’s looks really good – I may try and sneak in – your family may enjoy it 🙂 Details below…
