The genetic profiles of three Neolithic hunter-gatherers and one farmer who lived in the same region of modern-day Sweden about 5,000 years ago were quite different — a fact that could help resolve a decades-old battle among archaeologists over the origins of European agriculture, said study leader Mattias Jakobsson, a population geneticist at Uppsala University in Sweden.
The hunter-gatherers, from the island of Gotland, bore a distinct genetic resemblance to people alive today in Europe's extreme north, said Jakobsson, who reported his findings in Friday's edition of the journal Science. The farmer, excavated from a large stone burial structure in the mainland parish of Gokhem, about 250 miles away, had DNA more like that of modern people in southern Europe.

An ancient megalithic structure shaped like a ship in
Sweden seems to have a similar geometry to Stonehenge, and may have been
used as an astronomical calendar, one scientist says.

Despite the increase in the identification of these sites through aerial photography surveys since the 1970s, they are still generally rare and so are of immense significance.
Experts say the Meigle project represents the first complete excavation of a barrow cemetery to date, providing a unique opportunity to comprehensively analyse the monument.

"For Albania, there has been a significant gap in documenting the Early Neolithic (EN), the earliest phase of farming in the region," explains Allen. "While several EN sites were excavated in Albania in the '70s and '80s, plant and animal remains - the keys to exploring early farming - were not recovered from the sites, and sites were not dated with the use of radiocarbon techniques," Allen says.

Kolbert so skillfully manages the tricky task of weaving several concurrent stories through the one feature, that the reader is hardly aware of the jumps in a long piece that flows without crossheads or text-breakouts. Through it, she includes a profile of palaeogeneticist Svante Pääbo, the unfolding genetic and developmental story of human evolution, and the creation of fast-throughput genetic analysis, all infused within the central philosophical and scientific question of what it means to be human. Why are we so special? What enabled us to take over the world while our cousins are caged in zoos or extinct?

A standard approach

One of the conditions of approval for the Linden Homes development was that archaeologists could investigate the site before it was built upon.

Roman remains have been discovered at an archaeological dig at a Cambridge theological college which is planning a £9 million extension.
A major project to update and create state-of-the-art teaching and living space at Ridley Hall meant archaeologists were drafted in to carry out a survey.
After removing the topsoil the experts from Access Cambridge Archaeology discovered the “tantalising possibilities” of a Roman settlement, and even some remains dating back 3,000 years to the Iron Age.
A single bronze disc decorated with gold symbols that represent the sun, moon, stars and a boat, the Nebra Sky Disc is the world's oldest representation of the cosmos.
It reveals a prehistoric view of the world that before its discovery had never been known to exist, and has single-handedly reformed our understanding of ancient European history.
Known as the "Pompeii of the Aegean", the prehistoric town was buried under thick layers of volcanic ash during an eruption 3,700 years ago that may have destroyed the Minoan civilisation in Crete to the south.
"One of the most significant archaeological sites in Greece and the world opened its gates again," said Deputy Culture and Tourism Minister Petros Alivizatos. "Akrotiri, which is now fully safe, will attract visitors and boost Greek tourism."
The site was closed down in 2005 after its roof collapsed killing a 45-year old Welsh tourist. A new roof made of steel and wood now shelters the settlement discovered by Greek archaeologists in 1967.

For many years it was believed that humans didn’t use fire until about 800,000 years ago. But two College of Arts & Sciences archaeologists have found evidence in South Africa of a man-made fire dating back 1.2 million years, the earliest such discovery. The finding by Francesco Berna and Paul Goldberg substantially pushes back the date that humans laid the first kindling. Berna and Goldberg’s research was published yesterday in the online edition of Proceedings of the National Academy of Sciences.
