LONDON – next week, city of London, the United Kingdom will be host to a meeting of scientists from around the world. At a meeting that the plan will address the debate over water or Aquatic Ape Theory Ape Theory (AAT).

Ape hypothesis (AAH) water or water ape theory (AAT) is a hypothesis of human evolution, which holds that ancestors of modern humans spent a period of time to adapt to the presence of semiaquatic.[1][2] AAH arises from the observation that some human traits that set apart from other primates have in common with mammals. It was first proposed by pathologist Max Westenhöfer Germany in 1942, and then independently by the United Kingdom marine biologist Alister Hardy in 1960. After Hardy, most prominent supporters has been Welsh writer Elaine Morgan, who has written several books on the topic.

AAH has not accepted among the mainstream explanation of human evolution. The scientific consensus is that human beings first evolved during the period of rapid climate fluctuations between wet or dry, and that most of the adaptation that distinguishes humans from apes is an adaptation of the terrestrial, arboreal, compared to the previous environment. Some paleoanthropologists have explicitly evaluated AAH in scientific journals, and the people who have reviewed the theory has been critical. Extensive criticism appeared in a peer-reviewed paper by John h. Langdon in 1997.[3] Langdon stated that AAH is one of many hypotheses attempt to explain human evolution through a single causal mechanism, and that the fossil record does not support the evolution of the proposal; the hypothesis that is internally inconsistent, have the power of less obvious than its supporters claim, and that the hypothesis of terrestrial alternatives are much better supported. AAH is popular among lay people and continued support by a minority of scholars. Langdon this attribute on the appeal of a simple one-cause theories of more complex models, but better supported with some causality.

Disitat Softpedia, Thursday (29/4/2013), the theory says that human ancestors used to live on land but not in the water. Thus, man is regarded as a species that evolved from the apes slowly lost most of its feathers and began walking upright.

The ability to walk upright retrieved from ancestors who were able to swim to raise his head above the water surface. Meanwhile, the loss of body hair bristles are described because of the fat that there are just under the skin of the human body.
These fats are able to work better than the fleece to keep your body temperature to keep warm while in the water. Then, the transformation of the apes water also occur in relatively developed its brain size due to the consumption of seafood (seafood) which is rich in omega 3.

Scientists who support this theory claims that some of the idiosyncrasies of the anatomy of the APE of water is the same as in modern humans. One of them is a large cavity forms, thus being able to increase buoyancy when swimming in the water.

Interestingly, the water is believed to be descendants of the apes from ape trees that live in rivers and the sea as its successor. However, up to now many scientists oppose a theory first put forth by a pathologist from Germany, Max Westenhofer in 1942.

"If they (ancestors) live in the watery environment, then we spent millions of years in there and there is no evidence for this. This theory also does not make sense because what about the aquatic animals such as crocodiles and other dangerous creatures living there, "about scientists from the Natural History Museum in London, Professor Chris Stringer.

  1. FYI, an update of AAT. Better terms than ‘aquatic ape theory’ are littoral or coastal theory: rather than running over savannas as popular views of human evolution still believe, Homo populations during the Ice Ages (Pleistocene) followed the coasts (as far as Indonesia, the Cape & England) & from the coasts up rivers, collecting different waterside & shallow aquatic plant & animal foods.
