We hear a lot today about the ascent of man or woman, how humans evolved. This seems to be logical how humans split from other primates. I found it interesting concerning Ms Morgan's view that by the time humans 'left' their aquatic lifestyle, there has only been one human species.
I do not disagree or agree with that. It hints at a possibility concerning those 'semi-species' that might have co-existed with modern man at any time prehistory - their differences may have been only racial rather than a separate human species. Ms Morgan suggests that even the earliest austropicalus africanus, were far more human like in appearance than the general view among experts.
Still, her view on why people are what they are seems logical enough. She argues in this book that it was 10 million years ago when certain apes were forced to take to the water for protection while in the book Aquatic Ape, she decided that it was only 5 million years ago.
But even if woman and man are much older, there is no reason why he and she couldn't have evolved from a semi-aquatic lifestyle.
A fascinating and interesting book.
