was mankind aquatic ?

I had never realised that the above hypothesis was controversial, so I was surprised to hear a programme about it [Scars of Evolution, Radio 4 18 Apr 2005] narrated/hosted by Attenborough.

Ever since I read Elaine Morgan's book 'Descent of Woman' I have been a firm convert to the theory.

I feel that her title for the book probably caused it to be ignored?

She looked at the physiogomy of the human form and compared it to others
Very quickly her points were:
Man has no fur : relate to hippos etc.
Babies are born with LOADS of fat : essential in colder waters
Babies are born easier in water
Babies have swimming ability almost from minute 1
Humans have control over breathing : dolphins etc
Humans living away from the sea can have iodine deficiency
large brain needs loads of omega 3 fats [ found in aquatic animals]
Head hair is quite long [ easier for babies to grab hold of]
There was quite a lot more , certainly enough to convince most peole who read it - I cant remember all the salient points- its 25 years since I read it.

if you are wondering about the title, it goes as follows.
Animals mate in doggy style. If a female doesnt want sex, she can just walk away [literally]
Aquatic mammals mate face to face Once back on land the female could no longer walk away if she wanted. By this time the vagina had come much more towards the front of the body and the clitoris was a major source of pleasure for the female so face to face sex remained the most popular position

So there you have it, Google "descent of woman" for more info
