(I am republishing a lot of my ‘legacy content’ from our PLOS Neuroanthropology weblog, which has been taken down, along with many of the other founding PLOS Blogs. Some of these, I am putting up because I teach with them. If you have any requests, don’t hesitate to email me at: greg (dot) downey @ mq (dot) edu (dot) au. I suspect many of the links in this piece will be broken, but I will endeavour to try to slowly rebuild this content. Originally published 5 September 2010.)
Beginning in 2005, reports by Prof. Üner Tan of Cukurova University in Turkey alerted the world to a number of families in which some members walked quadrupedally. This is the second part of a (so far) two-part post on Uner Tan Syndrome. Although you’re welcome to read the first part, I’ll give you the one sentence summary if you just want to push on and a piece of video clip on the cases. I should warn you though, before you read the first part, that the whole thing is sort of like the straight set-up for this piece, which is a bit of a googly (kind of like a knuckleballer for all you non-cricket followers):
Üner Tan described four consanguineous Turkish families with fourteen individuals who habitually walked quadrupedally; subsequent genetic research showed that some of the families had defects in a gene known to be essential in cerebellar formation, but not all of the cases had the gene, and at least one family member with the gene walked normally, leading most researchers to argue UTS was genetically heterogeneous in origin; some theorists, including Tan, argued that quadrupedalism was either ‘reverse evolution’ or an atavism, but not everyone was buying that explanation (including me for reasons I didn’t make entirely clear in the first post).
Well, that was — technically — one sentence.
But if you read that first post, I know what you’re saying: ‘Bloody loooong post, mate, laffed mi head off at the picture… but eef thas what yous blokes do at Newroant-whatevs, well, I’m not heaps intristed.’ (Apparently, you have a bogan Australian accent, at least in my head.)

We’ve still got bipedal dogs and goats, kids who only get down on all four when in a hurry, Johnny Eck (aka the ‘Half Boy’), capoeira training in Brazil and some other surprises up our sleeve. We’ll show you how we roll at Neuroanthropology, with lots of weird SFW videos and obscure case studies!
One of the things that we try to bring to ‘neuro-’ to make it truly ‘neuroanthropology’ is a much more open consideration of human variation. This can sometimes take us to some extraordinary case studies, not simply out of a fascination with the exotic, but because a comparative look at extreme cases – like Uner Tan Syndrome – helps us to better understand human potential. So let’s go back to Prof. Tan…Continue reading “2 legs good, 4 legs better: Uner Tan syndrome, part 2”
