Did the first modern humans in Europe share a bed with nearby Neanderthals? Almost certainly not, according to a new analysis of 28,000 year old Cro-Magnon DNA.
The Cro-Magnons were the first modern Homo sapiens in Europe, living there between 45,000 and 10,000 years ago. Their DNA sequences match those of today's Europeans, says Guido Barbujani, an evolutionary anthropologist at the University of Ferrera, Italy, suggesting that "Neanderthal hybridisation" did not occur.

Ancient bones from the city of Jericho are to be used by British scientists to develop treatments for tuberculosis. The project is part of a new scientific discipline in which archaeologists and medical researchers are cooperating to gain insights into modern ailments.
Other diseases being tackled this way include syphilis, malaria, arthritis and influenza. Ancient history holds vital clues in seeking out treatments for modern diseases.

Somewhere in the murky past, between four and seven million years ago, a hungry common ancestor of today's primates, including humans, did something novel. While temporarily standing on its rear feet to reach a piece of fruit, this protohominid spotted another juicy morsel in a nearby shrub and began shuffling toward it instead of dropping on all fours, crawling to the shrub and standing again.
A number of reasons have been proposed for the development of bipedal behaviour, or walking on two feet, and now researchers from the University of Washington and Johns Hopkins University have developed a mathematical model that suggests shuffling emerged as a precursor to walking as a way of saving metabolic energy.

An archaeologist, who discovered the Hobbit, an ancient human like species, on an Indonesian island in 2003, has determined that a relative of the species may have existed in northern Australia.

Tel Aviv University finds humanity was divided for as much as 100,000 years
The human race was divided into two separate groups within Africa for as much as half of its existence, a Tel Aviv University mathematician has helped determine. Climate change, reduction in populations and harsh conditions may have caused the separation and maintained it.

The human race was close to extinction between 75,000 - 15,000 years ago due to severe environmental conditions, mainly the lack of water, a new gene study has revealed.
The research says that at one point the extinction was so close that the human race was down to "just 2,000 or fewer".

Ancient humans started down the path of evolving into two separate species before merging back into a single population, a genetic study suggests.
The genetic split in Africa resulted in distinct populations that lived in isolation for as much as 100,000 years, the scientists say.
This could have been caused by arid conditions driving a wedge between humans in eastern and southern Africa.

Oldest European

The remains of the oldest known western European have been discovered in a cave in Spain, pushing back the beginnings of human occupation in the continent by up to 400,000 years.
The jaw bone and teeth found in the Atapuerca hills, near Burgos in northern Spain, have been dated reliably to between 1.1 million and 1.2 million years ago, and probably come from a female who was among the first ancient humans to inhabit Europe.
She has been tentatively identified as a member of a species called Homo antecessor, or pioneer man, and lived 300,000 to 400,000 years before any other early humans (or hominins) are known to have reached western Europe.

A new genetic analysis of people from around the world adds further confirmation to the African origin of humans. The study of genetic details from 938 individuals from 51 populations provides evidence of how people are related and different, researchers led by Richard M. Myers of Stanford University report in Friday's issue of the journal Science.

War of words erupts over fossil dig
The Olduvai Gorge, perhaps the most famous location in palaeoanthropology, has become a battleground for two research groups. Last week the rivals met to resolve their differences, but tensions remain high.
