Guidance of Human Evolution

Evolutionary theory states that human ancestors were apes. However, like what the change from ape to man so the big question.

Now the mystery was answered. Fossil skeleton found in a child aged around two million years believed to be a new species of hominid - a mix of primates and humans. Remarkably, the fossils were relatively intact, not only parts of bones or teeth.

Scientists believe, that framework is a type of human ancestors that have not been studied before - who entered the advanced stages of human ape to man, also known as Homo habilis.


Experts who examined the skeleton said, the characteristics of Homo habilis, which emerged 2.5 million years ago is a key step in human evolution. This discovery is expected to fill the gap in human evolutionary history.

Hominid fossils previously found only in the form of bone fragments, so the discovery of a nearly intact skeleton enable scientists to answer key questions about what kind of human ancestors - when they began walking upright using two legs.

Framework found in Professor Lee Berger, of the University of Witwatersrand, while exploring a cave in Sterkfontein, South Africa, near Johannesburg. Containing limestone cave is believed to be important factors that maintain the integrity of the framework.

This discovery is very significant, to the point that the President of South Africa, Jacob Zuma, the university invited some experts to look at the fossils directly. Campaigns through the media and television documentaries are also being prepared.

Professor Phillip Tobias, one of three experts who first identified the Homo habisis in 1964, said the discovery as something extraordinary.

"The discovery of a framework, rather than just their teeth or arm bone, is very rare," said he, like the loaded pages of The Age, Monday, April 5, 2010.

Meanwhile, Dr Simon Underdown, human evolution expert from Oxford Brookes University said the new discovery is helping scientists better understand the evolutionary tree.

"The discovery like this makes us more understanding of our ancestors in those days they evolved into humans for the first time," he said.

This discovery is the most important and significant since the discovery of intact fossils 3.3 million years old, named Australopithicus, also known by the nickname 'little foot' in 1994.

Another great discovery was the intact skull from 2.15 million years ago Australopithecus africanus manifold, nicknamed 'Mrs Ples', in the year 1947
