Water or Savannah Apes? Where did humans evolve from?

Water or Savannah Apes? Where did humans evolve from?

As you can imagine the debate is getting heated. After Attenborough did his programme on humans evolving from marine apes the conservative human evolution establishment is up in arms. They do not like their current theory being challenged.

Human beings evolved from apes in the Rift Valley area of Africa about two million years ago. Not many, apart from the flat-eithers and creationists, are disputing that. We have the fossil evidence.

It is widely believed that we became bipedal on the African savannah in order to hunt and hold tools. The development of intelligence, along with binocular sight and the opposable thumb, necessary for tool manipulation, is well documented.

What David suggested was that we did not become biped on the savannah for hunting but developed this from wading in water to live off molluscs.

So what is the evidence for our aquatic past?

a. Evidence that primitive man ate a lot of bivalves

b. We have blubber (a thick layer of fat under the skin)

c. Babies are born with an immersion syndrome. They naturally hold their breath and can swim under water.

d. We have a physiological change when immersed. Our peripheral blood system shuts down and there are changes in metabolism and brain activity.

e. The hair deposition is of an aquatic animal.

f. We have an affinity for water. We love it.

It is an interesting idea. I look forward to seeing where it goes.

  1. That is fascinating. We have missed that one. Which series is it? By some fluke of our mobile wifi we can sometimes see iplayer. Hope you are well and your son recovering well.

      1. Scottish myth of seal people who turn human. Spelt four different ways, in google. I was attempting humour. 🙂
        Last Autumn I purchased a science magazine in the airport with this article “When the Sea Saved Humanity” by the archaeologist Curtis W. Marean. It considers the bottle-neck (die off) of humans between 195,00 and 123,000 BP and brings up data from the southern tip of Africa. An interesting read. Thank you for your blog!

I'd like to hear from you...
