Savanna Theory Versus Aquatic Ape Theory of Human Evolution :: Anthropology Essays Paleontology Papers

Savanna Theory Versus Aquatic caricature Theory of Hu troops EvolutionThe evolution of man is unvaryingly in question. While we are reasonably sure that modern humans and order Primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. gibe to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove. Both the Savanna Theory and the Aquatic imitate Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with replete questioning, each loses its accountability to rhetorical science. It was commonly believed that early hominids left the jungle to live on the open plains of Africa. Called the Savannah Theory, it was strongly promoted by professor Raymon d Dart, after he gained recognition for discovering the Taung skull in 1925. The Taung skull was the first admitted link among man and ape, and Prof. Dart based his theory on the modern place of the discovered fossils. However, a report in 2000 by Marc Verhaegen claims that a savanna evolution is extremely improbable. Based on biological and physiological data, he tries to disprove the savanna theory and suggests that our evolution would more likely progress in a humid and wet setting than the dry genus Oestrus of the grasslands. Humans have almost nothing in common with both surviving mammals of the savanna. Most mammals of hot, dry climates do not rely heavy on peeing for survival. They have a high tolerance to heat, and their system temperatures can fluctuate more than 6oC between day and night. They can sham a dehydration of 20%, whereas 10% or more would be fatal to humans. What little they do drink or consume by nature through food, is conserved bec ause they do not sweat. Hair and fur keeps the solarise off their direct skin, while humans would have to sweat 10-15 liters of water to physically cool down. (Verhaegen) Even structurally, humans and African land mammals male parentt have much in common.
