Elaine Morgan has been for years trying to persuade the academic community of the gigantic 'hole' in the story our ancestry and evolutionary process that made us lose our fur and become physically the homo sapiens we are today. This theory clearly demonstrates that humans have had an infinity with water from an early evolutionary age after the family tree split from our ape based distant cousins.
Although we do share a huge gene pool of similarities with apes we are incredibly different. This can easy be seen by our ability to swim in water, our bodies are perfectly adapted to water unlike any other land based animals on the planet. Simple proof of this theory is the remarkable ability for babies to naturally swim without coaching - throw a six month old baby in a swimming pool and it will hold its breath and swim, throw a six month old monkey or ape and it will drown!!
Elaine was kind enough to send her support to my hypothesis when my book as first published in 2010 as she understood that man would naturally use water in our evolution story, as he was by nature an 'aquatic ape' and this would manifest itself in later history when our ancestors used water to travel and trade - which meant that we probably safely 'floated' rather than walked dangerously 'out of Africa' some 50,000 years ago.
