Dr Eleanor Scerri, an archaeologist at Oxford University, who led the international research, said: Among the most important findings: T he species was also found to be several hundred thousand years older than the oldest African hominid, Sahelanthropus tchadensis which was found in Chad.
Instead, the international team argue, the distinctive features that make us human emerged mosaic-like across different populations spanning the entire African continent. The radiocarbon 14 method of determining the age of the fossil finds only allows the scientist to test an object that does not go back more than 50,000 years. So are these rolling hills truly the birthplace of humanity?
EXPERTS have long believed human lineage split from apes some seven million years ago in Africa, but a recent discovery is set to change this. The telltale characteristics of a modern human — globular brain case, a chin, a more delicate brow and a small face — seem to first appear in different places at different times.

Many ancient fossils and stone tools have been found there over the years. Because Zinjanthropus was much older than 50,000 years another newer method to determine the age of a fossil find was used. Meanwhile, some 97 percent of the continent has yet to be investigated by fossil hunters.
Not necessarily. The role in human origins of the Homo naledi skeletons from Rising Star hangs in limbo, awaiting experimental techniques that might solve the question of their age. While neither the fossils nor the ancient sediments they were found in could be dated directly, volcanic ash layers interspersed between the sediments, like layers of icing in a cake, could be dated by the clocklike decay of their radioactive elements, fixing limits to the age of the fossil-rich sediments above or below.
At a site called Malapa in 2008, and now in the Rising Star cave ten miles away, his team has uncovered unprecedented numbers of fossil bones, adding two completely new species to the human family tree.
There are five distinct layers of strata of the earth visible in the cliffs. Sign up.
