Our Aquatic Evolution

At school, university and in scientific programs you might see on TV, the explanation of how we evolved from apes to humans is only about the Savannah theory, which goes something like this

In times of climatic change when forests were retreating in Africa, some of the apes living in trees were forced to come down from the trees and live on the African plains.

In this dangerous environment where carnivorous animals like lions and hyenas lived, this ape become a top carnivorous animal itself, through learning how to use tools and weapons to hunt and kill other animals and fight off predators. (This theory is also called the killer-ape theory).

In the 1960s this was considered to be the undisputed theory of why humans evolved from apes, but one feminist called Elaine Morgan had a number of strong objections to this theory and voiced them in a book called, “The Decent Of Women”. In this book she made the point that in the Savannah theory, the role of women and children is not mentioned at all. But when she asked the question what were women and children doing while man the mighty hunter was out hunting, the whole theory fell apart

This is because in the animal kingdom the human baby is more helpless than any other animal. It can take up to two years before it walks and takes 15 to 20 years to grow to full size. So how did mothers ensure the safety of themselves and their children in open plains? Where you had predators like lions, hyenas, leopards, cheetahs and jackals.

Another point was that another primate the baboon also came out of the forest and learnt to live on the plains but it didn't evolve human like characteristics. There is very little difference between a forest baboon and a Savannah baboon.

Sir Alistair Hardy And Elaine Morgan

Elaine Morgan then mentioned a far better theory on how apes evolved into humans, the Aquatic Ape theory, which was proposed by the scientist Sir Alister Hardy.

As a marine biologist he noticed the striking similarity between the blubber of marine mammals like seals and dolphins and the layer of subcutaneous fat around human beings.

This wasn't present in any other primate. He also noticed that all large marine animals were hairless like a human being. From this he concluded that human beings must have once lived in an aquatic environment in their evolution from ape to human

Unfortunately Sir Alister Hardy received such a negative response from his colleges about his theory that he dropped it, but Elaine Morgan took up its cause and wrote about it further is a series of books called. “The Aquatic Ape Hypothesis”, “The Descent of the Child: Human Evolution from a New Perspective” and “The Scars of Evolution”

Elaine Morgan in her books developed the theory further and was able to explain not only why human beings were naked and had subcutaneous fat, but why we walk upright, why we talk, why we sweat and cry, and why we have far larger brains than any other ape.

Unfortunately even though she was able to make a strong case for the Aquatic Ape Theory, male scientists have still preferred the Savannah Theory, or Killer Ape theory, simply because this theory gives men the staring role in human evolution. But this has changed in recent times when more archaeological finds of early humans undermine the case for the Savannah Theory and support the Aquatic Ape Theory.

Aquatic Ape Video On Youtube

There are a number of videos on Youtube on the Aquatic Ape Theory but when doing this hub-page I realized just how difficult it is to navigate around Youtube to find them all.

So i have made up a blog, where they are all in one place. - As well as more of my articles on the Aquatic Ape Theory.

Thank you Marc, for the links.

marc verhaegen on June 19, 2013:

Humans didn’t descend from aquatic apes, of course, although our Pleistocene ancestors were too slow & heavy for regular running over open plains as some anthropologists still believe.

Instead, Homo populations during the Ice Ages (with sea-levels often 100 m lower than today) simply followed the coasts & rivers in Africa & Eurasia, eg, 800,000 years ago, they even reached Flores more than 18 km overseas.

Hi Marian Swift

Sir Alister Hardy did first speak of it back in the late 1960s and it got a lot of publicity but then it was forgotten. And it would of remained forgotten if it wasn't for Elaine Morgan.

The first scientific paper on the Aquatic Ape theory was back in 1943 by a german scientist.

Marian Swift from San Francisco Bay Area on November 04, 2008:

I remember reading a magazine article on the Aquatic Ape Theory back in the 60s(!!!).  I don't remember the author, but the concept made a lot of sense to me.  Then I forgot all about it ... until now.

Many thanks for the reminder and the update!

Hi Steve

I'm afraid you will have to got to go to Youtube to see all the Aquatic ape and Elaine Morgan videos. I suppose it depends if you like the first ones i have shown and want to see more.

Hi Lady Guinevere

I forgot to metion on the first video one the Aquatic Ape theory it does show a swimming baby.


Steve Andrews from Lisbon, Portugal on November 02, 2008:

Hi William! I am glad to see you have published this excellent new hub! I will watch the videos tomorrow because it is nearly midnight and I have been out all day!

Debra Allen from West By God on November 02, 2008:

oooooohh yeah. I saw the male gener thing the first week of being married to my current husband..and I see it here from some friends.

Hi C.J. Stone

I read, "The Decent of Women" when it was first published. Back in the 1970s I had an uncle who got me interested in Stone-Age Man and I read a few books on it from my local library. Then I came across the “Decent Of Women” and very much liked it. I preferred her explanation than the ‘killer-ape’ stuff I had been reading. I naively lent the book to my uncle and was surprised when later he told me how much he disliked it.

I was also later surprised at the scientific establishments opposition to the Aquatic Ape Theory and it took me some time to understand it was all about gender politics.


Christopher James Stone from Whitstable, UK on November 02, 2008:

Hello William, I've always held to the Aquatic Ape theory ever since i read it in the Descent of Woman back in the eighties. Yes it makes perfect sense and also explains why all humans have a strong feeling, a longing almost, for the sea. When I first read the book I'd just moved into this small sea side town where I live now, so it coincided with daily swims in the sea and with eating oysters and other seafoods, all of which probably helped to convince me of the theory. Glad to read it again here and to once more finding myself in complete agreement.

HI Lady Guinevere

The Bible to was written by men with an agenda to promote male supremacy. The first diety humans worshipped was the Great Mother. So the Bible was a reaction against this and was promoting a male god with a male priesthood.


Debra Allen from West By God on November 01, 2008:

I think a lot of the sexism comes from Genesis because it says the Adam was made first and then came Eve and somehow they come to the conclusion that since Eve was second that she is inferior................but...................she was made from Adam which only makes sense that they are equal because they have the same genes. I also posted something in one of my hubs that if we were made in God's image and liekness that we have brains and actions like them too which only proves that they were intelligent in the Garden of Eden-so they what---all of a sudden became dumb and they blame it on the women. Where was Adam--twittling his thumbs in another part of the Garden? That makes no sense because they didn't know of anyplace but there then and he had to have seen or heard them talking. It is easy to blame it on someone else to make themselves be the superior race--but it makes them look stupid because they ate the same fruit....and they are neither are supoerior....hmmmmm

William Bond (author) from England on November 01, 2008:

Hi Lady Guinevere

Thank you for being the first to comment on my Hub.

Water births is nothing new, the Sea Gypsies of South East Asia have been doing it for thousands of years. In most Sea Gypsy families the children learn to swim before they learn to walk.

As for the male scientists being egoistic and arrogant. In Elaine Morgan's Lecture at University College London, she expresses total bewilderment, because as far as she is concerned she has won all the scientific arguments. But the scientific establishment still refuse to accept the Aquatic Ape Theory. I know think the reason for this is pure sexism. The Savannah theory, which the scientific establishment clings to, gives men, the whole credit for our evolution from apes to man. If also establishes the idea that men have always been the dominant sex since we evolved from apes. This is because the Savannah theory claims that early man was carnivorous and therefore very violent, and probably used his violence to keep their women ‘in line’.

The Aquatic Ape Theory doesn’t show early humans as violent and therefore doesn’t support the idea of male dominance in pre-historic times. And this is the reason the scientific establishment does not like it.


Debra Allen from West By God on November 01, 2008:

I didn't watch the youtubes but I can understand part of the theory. Some mother's are electing to have their children in water and the children when born have no problem being in the woter. Some babies when put in water right after birth can and do swim effortlessly--like dolphins ans such. I also beleve in mermaids and that they are not seacows or manatees. The male gender is egotistical and arrogant in what and how we evolved. They don't even think of women and children. That needs to stop!
