Could the Balkans, rather than previously accepted areas such as the Strait of Gibralter, have been the entry point for the first men in Europe?
A team of 20 Bulgarian and French archaeologists are trying to prove this theory after 11 years of excavation and research in the Kozarnika cave in northwestern Bulgaria.
The digging up at this mountainous site of traces of human activity dating back 1.4 to 1.6 million years throws into question theories about when and where man first set foot in Europe.
According to current theories, the Europeans' prehistoric ancestors came into southern Europe from Africa by crossing the Strait of Gibraltar or the Sicilian channel around 800,000 years ago.

Oldest human footprint

Archaeologists in Egypt say they have discovered what might be the oldest human footprint ever found.
The outline was found imprinted in mud, which has since turned to stone, at Siwa oasis in the western desert.

Egyptian archaeologists have found what they said could be the oldest human footprint in history in the country's western desert, the Arab country's antiquities' chief said on Monday.

"This could go back about two million years.  It could be the most important discovery in Egypt" - Zahi Hawass, the secretary general of the Egyptian Supreme Council of Antiquities.

Archaeologists found the footprint, imprinted on mud and then hardened into rock, while exploring a prehistoric site in Siwa, a desert oasis.

Two University of Utah geologists helped date volcanic ash deposits used to determine the ages of two early human fossils that were discovered in Kenya and challenge popular notions of how humanity evolved.
The study, published in the Thursday, Aug. 9 issue of the journal Nature, was conducted by nine researchers, including famed palaeontologist Meave Leakey, her daughter Louise Leakey and University of Utah geologists Frank Brown and Patrick Gathogo.
The first fossil is a 1.44 million-year-old jawbone of Homo habilis, (KNM-ER 42703) the earliest species of our genus, Homo. It shows that for a half-million years, two species of early humans lived side by side in Africa, contrary to the old view that one species, Homo erectus, evolved from the other, Homo habilis.

It is a rock, weighing maybe two pounds, and it has been chipped to be more or less round. It fits comfortably in my hand like a slightly oversize baseball.
I can grasp it the way Homo habilis held it more than a million years ago, perhaps using it to beat an antelope carcass until some bits of meat came off or until a knee broke and could be ripped from a thigh and dragged to the safety of trees to be eaten. ''Stone Age tool'' ceases to be an abstract concept.

One of the world's leading palaeontologists denounced Ethiopia's decision to send the Lucy skeleton on a six-year tour of the United States, warning Friday that the 3.2 million-year-old fossil will likely be damaged no matter how careful its handlers are.
The skeleton was quietly flown out of Ethiopia earlier this week for the U.S. tour.

Fossils often have provided important insights into the evolution of humans and our ancestors. Even small fossils, such as bones from the hand or foot can tell us much about our ancestors and their behaviour. Such may be the case with an ape that lived more than nine million years ago.

It was both the king of the swingers and a tree-walker. A new study of an extinct ape suggests it had the hands to both swing from branches and walk along them on all fours. But no one knows whether it was an evolutionary dead end or a key step in the evolution of the tree-dwelling lifestyle led by modern orang-utans.
A study of a 9.5-million-year-old fossil of the ape Hispanopithecus laietanus reveals that it had fingers that were longer than those of a modern gorilla or human, but not as long as those of an orang-utan: an arrangement of bones unique among all known apes, alive or extinct. That would have allowed it to hang from tree branches as orang-utans do, but also walk on all fours along the larger branches with its palms flat on the surface.

Two hominid fossils discovered in Kenya are challenging a long-held view of human evolution.
The broken upper jaw-bone and intact skull from humanlike creatures, or hominids, are described in Nature.
Previously, the hominid Homo habilis was thought to have evolved into the more advanced Homo erectus, which evolved into us.
Now, habilis and erectus are now thought to be sister species that overlapped in time.

Early human-like residents of Europe may have arrived out of Asia, rather than just Africa.
An international team of researchers reports in Monday's online edition of Proceedings of the National Academy of Sciences that Asians appear to have played a larger part in the settlement of Europe than did Africans.
The team led by Maria Martinon-Torres of the National Centre for the Investigation of Human Evolution, in Burgos, Spain, reached that conclusion after analysing more than 5,000 fossil teeth from early hominins, an early form of human predecessors.
After studying ancient teeth from Africa, Asia and Europe, the researchers report that early European populations had more Asian features than African ones.
That conclusion also supports the theory that the development of the genus Homo -- modern humans are Homo sapiens -- occurred both in Africa and Asia.
The teeth studied were from the genera Homo and the earlier Australopithecus.
