An analysis of the human evolution of the water theory by elaine morgan

He nevertheless criticized the AAH because "it's always a problem identifying features [such as body fat and hairlessness] that humans have now and inferring that they must have had some adaptive value in the past.

Oren Harman and Michael R. But no other mammal has ever resorted to this strategy. Wherever the early members of the human family were evolving, they needed water to drink and to keep cool. At the time she had been reading a lot about 'man the hunter' and other savannah hypothesis related views of how humans had evolved in such a way to benefit the male of the species while failing to consider at any time the females or the young.

On the advice of his colleagues, Hardy delayed presenting the hypothesis for approximately thirty years. It was this dietary health angle that led Crawford, independently to the same conclusion as did Elaine Morgan, at about the same time, that coastal scenarios were more plausible in explaining the human condition than savannah ones.

Probably did also physiological traits as the human diving response, neonatal swimming reflexes and diving reflex evolve over time, not only during a short period of time million years ago.

Some interest was received, notably from the geographer Carl Sauer whose views on the role of the seashore in human evolution [15] "stimulated tremendous progress in the study of coastal and aquatic adaptations" inside marine archaeology.

It is good for insulation in water, and for giving buoyancy. One of its strongest proponents in the past, Professor Phillip Tobias, publicly declared that those who based their thinking on it had been on the wrong track, and new thinking was called for.

Erika Lorraine Milam is an associate professor at the history department of Princeton University. When they decide how deep they are going to dive, they can estimate how much air they need to inhale. That is why in our species food and drink may sometimes go "down the wrong way". Wading and bipedalism[ edit ] After reviewing 30 different explanations of bipedalism, evolutionary biologist Carsten Niemitz proposed a "shore dweller" hypothesis of wading, though distancing himself from the AAH.

Key Proponents and supporters of AAT

In the case of AAT, progress was very slow. Of course, not all attention is good attention. No land-based predator can afford to get fat. Among the hundreds of living primate species, only humans are naked.

The other human peculiarity is called "the descended larynx".

The Aquatic Ape Hypothesis (Condor Independent Voices)

We weep tears of emotion, controlled by different nerves from the ones that cause our eyes to water in response to smoke or dust. One is that they are never born fat. This poses two questions: Paleoanthropologist Adrienne Zihlmanfor example, worried that after reading the book, other scientists might think this was the best feminist anthropology had to offer.

Seemingly it was under just such a set of conditions that the Hominidae made their appearance upon the face of the earth. That is the real lesson of the aquatic ape theory.

She is the author of Looking for a Few Good Males: One, the proboscis monkey, lives in the mangrove swamps of Borneo. A conference devoted to the subject was held at ValkenburgNetherlands in The only way human ancestors could have done this, he thought, was if they first inhabited a totally new ecosystem, which enabled the evolution of increased brain-power, complex vocalizations and foresight.

There is no known reason why an ape should suffer more from overheating than the savannah baboon.

Aquatic ape hypothesis

Humans differ from apes in a surprising number of ways. But the general policy is to play down the change in thinking as nothing more than a slight readjustment I. Personal life[ edit ] Elaine Floyd was born and brought up in Hopkinstownnear Pontypriddin Wales.

But there is not a single instance of this, not even among species like baboons and vervets, which are descended from forest- dwelling ancestors. Tobias did not espouse the aquatic ape hypothesis as a primary cause for for instance our bipedalismsince there are other theories, but to his knowledge no other hypothesis could explain those several physiological and biochemical characteristics which seem to ally us to aquatic mammals.

For instance, she thought that if humans lost their fur in order to cool down while chasing game on the savannah, that did not explain why women should also lose their fur as, according to the savannah hypothesis, they would be looking after the children.

He is closely linked with the archaeological excavation at the Sterkfontein caves, which have yielded the largest single sample of Australopithecus africanus as well as the first known example of Homo habilis from Southern Africa.

Even if you are right, you will need a lot of persistence, a very thick skin, and a fair share of luck.

In this new packaging, her marine musings began to receive more attention. Darwin found that very puzzling because it means that the opening to the lungs lies side by side with the opening to the stomach. Features such as the detailed structure of the larynx, nose, ear, female external genitals and the kidneys led Sera to consider the possibility that the platyrrhines might once have occupied an aquatic habitat.

Elaine Morgan and the Aquatic Ape

The professional journals maintain almost unbroken their policy of avoiding any mention of the aquatic hypothesis, but on the whole I have come to find that silence reassuring.

The Aquatic Ape: A Theory of Human Evolution, by Elaine Morgan; (c), Stein and Day Press, pages hardcover. Biology textbooks often offer the "just so" story of human evolution: driven from the forests by drought, survival on the savanna by group hunting and scavenging that required language development and promoted tool use─all centering on the man as izu-onsen-shoheiso.coms: Elaine Morgan The Descent of Woman, The Aquatic Ape, The Scars of Evolution, The Descent of the Child, The Aquatic Ape Hypothesis and The Naked Darwinist () discuss the reception of aquatic scenarios in academic literature.

Elaine Morgan and the Aquatic Ape

The theory of an aquatic phase in human prehistory was conceived by Sir Alister Hardy inwhen he was a young professor of marine biology at Oxford. He waited for thirty years before publishing an account of it, having a shrewd idea how it would be received and how it might damage his career.

Aquatic Ape Theory Elaine Morgan "An aquatic Ape is a likely ancestor of humans in terms of primate behaviour, marine ecosystems and geophysical timing.".

Aquatic ape hypothesis

Jul 31,  · Elaine Morgan is a tenacious proponent of the aquatic ape hypothesis: the idea that humans evolved from primate ancestors who dwelt in wat. Elaine Morgan and other aquatic ape theory proponents have cited various other differences between humans and other LCM descendants that may support the aquatic ape theory theory, such as the presence of salt glands, skin thickness, and mating postures.
