Elaine Morgan says we evolved from AQUATIC apes!

    Good post. She makes a convincing presentation!
    Here are some of the arguments against, compliments of wikipedia

    "Specific criticisms include inconsistencies within the theory, the failure of the fossil record to support the claims and the theory is not parsimonious despite claims that it is. To Morgan's statement that wading into shallow water would help protohumans avoid predation from lions and hyenas, it was pointed out that this would present the risk of being attacked by aquatic animals such as crocodiles and hippopotami that present a current risk to Africans living near bodies of water,while lacking the fangs, claws or size to defend themselves. Humans would lose body heat quickly out of water; most similarly-sized aquatic mammals have dense, insulating fur. Hairless skin is only an advantage for fully-aquatic mammals that dive, swim quickly or migrate long distances such as whales and dolphins.Many aquatic mammals are covered with dense fur but swim very well, and have fatty layers beneath the skin; in many cases the imperfections help with streamlining due to laminar flow. Humans also lack immune system defences to protect against the waterborne parasites. The position, evolutionary timing of changes, and size of the nerve openings in the vertebra suggest that breath control in humans improved because of the increased complexity and use of speech rather than an aquatic phase of evolution. The loss of body hair is also explainable through a lower parasite load and maintained through sexual selection"

    Isn't hair loss also associated with genetic mutation too?
