Human Ancestors Apparently Diverse

F. Spoor Fossil skull was discovered in 1972 in kenya, referring to the species of human ancestors, Homo rudolfensis.

NAIROBI, KOMPAS.com — Findings confirm the existence of the fossil skull of new species Homo rudolfensis and suggests that the ancestors of humans proved to be diverse.

The fossil was discovered in Koobi Fora, a desert region of Northern Kenya. Fossil key that indicates the existence of H is lower jaw fossils rudolfensis fossils of ancient humans that chicks face.

"This Fossil has a flat face, you could make a straight line from the eye to the incisors of fossils," says Fred Spoor of the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany, which involved research, was quoted as saying Thursday Livescience, (8/8/2012).

"These Fossils have characteristics that are different, really shows something new. I'm sure we don't just look at the variation in a species, "added Meave Leakey, palaentolog Turkana Basin Institute in Nairobi.

H. rudolfensis was first described based on fossil skull found in 1972 in Kenya, KNM-ER 1470, called.

At that time, it has been known species H and h. sapiens that habilis also ancestors of humans. H. rudolfensis was considered different because it has a size larger than h. habilis.

Alas, that was found is not part of the face and jaw. Thus, palaentolog is still difficult stated that it was indeed H rudolfensis fossils.

Fossil findings this time make the scientists more convinced that H does exist, life rudolfensis along H habilis and h. sapiens.

However, confidence is not 100 percent. Lower jaw fossil KNM-ER code 1802 had the upper part of the mouth are more circular, the characteristics of which are owned by h. rudolfensis.

Scientists predict, these fossils belong to the species h. habilis. However, until the fossils were discovered, scientists h. habilis also could not believe. It could be, it is also a property of fossil species.

As reported in Nature, on Wednesday last week, this discovery suggests that the ancestors of the human variety, coexist at 1.7 to 2 million years ago.

During this time, it is understood that human evolution progresses like a straight line, a species of extinct ancestors is replaced one more new species. Through this research revealed that it is possible that more than one ancestor species alive at the same time and competing with each other. That win, he existed and was able to survive.
