Last October I posted Elaine Morgan’s TED talk, in which she argues quite compellingly in favour of the “Aquatic Ape Theory”, a theory suggesting that there was an aquatic phase in our evolution.

Yesterday I discovered that there was a BBC documentary made in 1998 about Elaine and her championship of the theory. It’s on youtube in its entirety (Part 1, above).

It’s a good summary of the basis of the theory, and it also includes criticism of the theory by scientists.
