A giant African lake basin is providing information about possible migration routes and hunting practices of early humans in the Middle and Late Stone Age periods, between 150,000 and 10,000 years ago.
Oxford University researchers have unearthed new evidence from the lake basin in Botswana that suggests that the region was once much drier and wetter than it is today.
They have documented thousands of stone tools on the lake bed, which sheds new light on how humans in Africa adapted to several substantial climate change events during the period that coincided with the last Ice Age in Europe.
Researchers from the School of Geography and the Environment at the University of Oxford are surveying the now-dry basin of Lake Makgadikgadi in the Kalahari Desert, which at 66,000 square kilometres is about the same size of present day Lake Victoria.

Humans may have reached Europe far earlier
Geologists at a Berkeley research centre have muddied the already murky waters of human evolution by showing that our early human ancestors and their stone tools must have reached Western Europe from Africa a full half-million years earlier than anthropologists have thought.

We are born to believe in God

Atheism really may be fighting against nature: humans have been hardwired by evolution to believe in God, scientists have suggested.
The findings challenge campaigners against organised religion, such as Richard Dawkins, author of The God Delusion. He has long argued that religious beliefs result from poor education and childhood "indoctrination".

Europe's oldest axes discovered
Hand axes from southern Spain have been dated to nearly a million years old, suggesting that advanced Stone Age tools were present in Europe far earlier than was previously believed.

Milk drinking started in central Europe
The ability to digest the milk sugar lactose first evolved in dairy farming communities in central Europe, not in more northern groups as was previously thought, finds a new study led by UCL (University College London) scientists published in the journal PLoS Computational Biology.

80,000 year old shells point to earliest cultural trend
Perforated Nassarius gibbosulus dated to between 73 400 and 91 500 years ago.
Shell beads newly unearthed from four sites in Morocco confirm early humans were consistently wearing and potentially trading symbolic jewellery as early as 80,000 years ago. These beads add significantly to similar finds dating back as far as 110,000 in Algeria, Morocco, Israel and South Africa, confirming these as the oldest form of personal ornaments. This crucial step towards modern culture is reported this week in the Proceedings of the National Academy of Sciences of the USA (PNAS).
A team of researchers recovered 25 marine shell beads dating back to around 70,000 to 85,000 years ago from sites in Morocco, as part of the European Science Foundation EUROCORES programme 'Origin of Man, Language and Languages'. The shells have man-made holes through the centre and some show signs of pigment and prolonged wear, suggesting they were worn as jewellery.

Fossils for All: Science Suffers by Hoarding

Before this tour, Lucy had never been on public display outside of Ethiopia. One might expect scholars of human evolution to be delighted by the opportunity to share the disciplines crown jewel with so many members of the science-interested public. But news reports announcing her New York debut included the same objections that aired when she first landed in the U.S.: namely, that the bones could sustain damage and that the tour takes a key specimen out of scientific circulation for too long. Indeed, some major museums turned the exhibit away in part for those reasons.

Homo floresiensis

The identity of the tiny human-like creature discovered on the Indonesian island of Flores in 2004 has become clearer -- and more astonishing -- thanks to a new analysis by Australian and Indonesian scientists.
According to a team led by Australian National University doctoral student Debbie Argue, not only is Homo floresiensis, nicknamed the hobbit, not a deformed modern human, as a handful of critics claim, but the small-brained, long-armed biped was the first human-like creature to walk out of Africa.

Early modern humans in South Africa were using "heat treatment" to improve their stone tools about 72,000 years ago, according to new research.
This technique may bridge a gap between the use of fire to cook food 800,000 years ago and the production of ceramics 10,000 years ago.
Evidence for this innovation was found at Pinnacle Point, a Middle Stone Age site on the South African coast.
The researchers have published details in the journal Science.

World population projected to reach 7 billion in 2011
The world's population is forecast to hit 7 billion in 2011, the vast majority of its growth coming in developing and, in many cases, the poorest nations, a report released Wednesday said.
