The so-called aquatic ape hypothesis is one that has attracted a lot of attention and much derision. In 1960, British marine biologist Alistair Hardy posited the idea that humans might once have had an aquatic phase (or more accurately a semi-aquatic phases, spending some time in a watery habitat but a significant amount of time on land). This was picked up highlighted in popular zoologist Desmond Morris’s book The Naked Ape . However, Elaine Morgan was one of the the hypothesis’ main promoters, writing a book called The Aquatic Ape Hypothesis . There have been several debunkers of the hypothesis including Southern Fried Sciences’ own David Shiffman although Jim Moore’s website is probably one of the most comprehensive debunking sites for the hypothesis . Today Alice Roberts and Mark Maslin posted a critique of the aquatic ape hypothesis, mostly in response to a new BBC radio series The Waterside Ape which is being presented by David Attenborough.
