Simon Waters pointed out that the AquaticApe.org site which exists to analyse all the evidence about such issues . Based on that I am convinced that the Aquatic Ape theory has little merit.
My mistake was to put too much faith in the organisers of the TED conference. They have a good history of inviting speakers who know their stuff. I recently analysed the facts behind one dubious claim made in a TED talk, but that case was a single claim which was not required to support the essential points of the lecture . I expect other mistaken claims such as that one from any lecture anywhere, in a TED lecture I expect the central point to be well supported but it seems that my expectation was incorrect.
I will be more skeptical about TED talks in future.
Thanks Simon for correcting me on this issue! One of the advantages of blogging is that when (not if) you get something wrong there is likely to be someone out there with a good reference to evidence to the contrary.
