Child fossil find may be man's missing link 
RICHARD GRAY, LONDON 

April 5, 2010 
A skeleton discovered in South Africa has scientists abuzz.

A ''MISSING link'' between humans and their ape-like ancestors has been 
discovered.

The new species of hominid, the evolutionary branch of primates that includes 
humans, will be revealed when the 2-million-year-old skeleton of a child will 
be unveiled this week.

Scientists believe the almost-complete fossilised skeleton belonged to a 
previously unknown type of early human ancestor that may have been an 
intermediate stage as ape-men evolved into the first species of advanced 
humans, Homo habilis.

Experts who have seen the skeleton say it shares characteristics with Homo 
habilis, whose emergence 2.5 million years ago is seen as a key stage in the 
evolution of our species.

The discovery could help rewrite the history of human evolution by filling in 
crucial gaps in scientific knowledge.

Most fossilised hominid remains are little more than scattered fragments of 
bone, so the find of an almost-complete skeleton will allow scientists to 
answer key questions about what our early ancestors looked like and when they 
began walking upright on two legs.

Palaeontologists and human evolutionary experts behind the discovery have kept 
silent about the exact details of what they have uncovered, but the scientific 
community is abuzz with anticipation of the announcement of the find on 
Thursday.

Professor Lee Berger, of the University of the Witwatersrand, found the 
skeleton while exploring cave systems in the Sterkfontein region of South 
Africa, near Johannesburg, an area known as ''the cradle of humanity''.

The find is deemed so significant that South African President Jacob Zuma has 
visited the university to view the fossils and a media campaign with television 
documentaries is planned.

Professor Phillip Tobias, an eminent human anatomist and anthropologist at the 
university who was one of three experts to first identify Homo habilis as a 
species of human in 1964, described the latest discovery as wonderful and 
exciting.

He is one of the few scientists outside the research group behind the discovery 
who have seen the skeletons.

''To find a skeleton, as opposed to a couple of teeth or an arm bone, is a 
rarity. It is one thing to find a lower jaw with a couple of teeth, but it is 
another thing to find the jaw joined on to the skull, and those in turn uniting 
further down with the spinal column, pelvis and the limb bones,'' he said.

''It is not a single find, but several specimens representing several 
individuals.''

The fossil skeleton was found along with several other partially complete 
fossils, encased in breccia sedimentary rock inside a limestone cave known as 
Malapa cave.

The fossil record of early humans is notoriously patchy and scientists hope 
these remains will provide fresh clues about how our species evolved.

Scientists believe a group of ape-like hominids, Australopithecus, which first 
emerged in Africa about 3.9 million years ago, gradually evolved into the first 
Homo species. About 2.5 million years ago, Homo habilis, the first species to 
be described as distinctly human, began to appear.

The latest research by Giorgio Bertorelle and his team from the University of 
Ferrara in Italy, compared genetic material from Neanderthals, Cro-Magnon 
humans and 21st-Century Europeans. The DNA from the Neanderthals and 
Cro-Magnons was taken from their bones. The genetic material was extracted from 
cell structures called mitochondria rather than the nucleus. The scientists 
found that while, unsurprisingly, modern humans show clear genetic signs of 
their Cro-Magnon ancestry, no such link between Neanderthal DNA and modern man 
DNA could be established.

It is thought the fossil to be unveiled this week will be identified as a new 
species that fits between Australopithecus and Homo habilis.
