This programme will be available shortly after broadcast.
Sir David Attenborough considers whether new evidence will help a once ridiculed theory of human origins move towards to mainstream acceptance.
In 1960, the eminent Oxford marine biologist Sir Alister Hardy proposed a revolutionary idea:
our human ancestors had started their existence, not on the wide savannahs of Africa, but had become accustomed to living alongside water, swimming & diving in the shallows, collecting the abundant food & learning to use language & fashion tools.
Hardy asserted that this adaptation to living at the waterside would also account for a whole range of peculiarities about the human form:
the layers of fat beneath the skin, the relative lack of body-hair, the development of language & speech, and what has been called our 'runaway brains'.
Perhaps surprisingly, it was a screen-writer rather than a scientist, Elaine Morgan, who took up Hardy's theory, and, for over 40 years, progressively refined the evidence for the idea.
Most mainstream paleo-anthropologists rejected the Hardy-Morgan thesis for decades,
but some influential scientists asked for the proposal to be approached with an open mind.
Sir David Attenborough first considered the controversial theory on Radio 4 in 2004.
In this new series of 2 programmes "The Waterside Ape", he brings us up to date with the story & the evidence put forward since then - both for the hypothesis & also for its continuing detractors.
Back in 2004, Sir David asked Elaine Morgan how long it would take for the aquatic adaptation theory to become a mainstream account of human origins.
She answered, "I'll give it 10 years."
As we review the new evidence, has she been proved right?
