http://news.bbc.co.uk/1/hi/world/africa/4357986.stmChad is celebrating the opening of its first palaeontology department - only the fourth in Africa - following a discovery which shook up the understanding of human origins. Until a few years ago, most people thought that human life began in East Africa's Rift Valley.
Famous scientists like Dr Louis Leakey helped make the region famous, and called the area the Cradle of Mankind.
But in July 2002, a fossil was found in Chad which contradicted all previous
The discovery of a seven million-year-old skull, nick-named Toumaï, suggested that the Cradle of Mankind is further west, in the heart of central Africa.
The man who found Toumaï, French palaeontologist Professor Michel Brunet, on Tuesday helped open Chad's first palaeontology department.
He hopes it will train young Chadians to follow in his famous footsteps.
"For me today is a great day because now you have the first palaeontology department at the University of Ndjamena - it's just the beginning of something.
"Before Toumaï, we thought that the Cradle of Mankind was somewhere in East Africa so now we know that it's wrong, it's not the truth."
The new palaeontology department will have space for 46 students, as well as a high-tech laboratory to analyse the fossils.
The head of the new unit, Dr Mackaye Hassane Taisso, set out his ambitions for the future.
"Listen, Toumaï is seven million years old, so our ambition is to find something older," he told the BBC.
"If we find a fossil about 10 million years old, that would be great. We are placing the bar very high, but we need to."
Although it was Professor Brunet who led the team that found Toumaï, the skull itself was actually unearthed by a Chadian researcher, Ahounta Djimdoumalbaye.
"I first saw it three metres away," he recalls.
"Something was glistening in the sun - it was some teeth. My first thought was that it was a type of small pig.
"I looked at it all over - it was covered with sediment. It was only when I turned it over and I saw these two holes - the orbits for the eyes - that I realised it wasn't a pig, it was a real discovery."
Mr Djimdoumalbaye has a reputation for being a brilliant fossil finder.
Asked if he thinks he can find an even older human fossil, he is bullish.
"Why not? The next thing however to find is a complete skeleton, because at the moment we've only got the skull. If we find a complete skeleton, that's our dream now. The conditions are there, so there's no reason not to find it."
The discovery of Toumaï turned the scientific community upside down, and researchers are now focussing on Chad's rich fossil reserves.
With the opening of its very own palaeontology department, there is now every chance of yet more amazing discoveries in this, new, Cradle of Mankind.
