Sophisticated stone tool-making, artistic symbolism and trade networks were all innovated during times in the Stone Age when the South African climate abruptly became warmer and wetter, according to a new study.

The research is the first to “show that there is a link between the occurrence of these cultural innovations and climate change,” study leader Martin Ziegler, an earth science researcher at Cardiff University in Wales, told NBC News.

Will ‘hobbit’ tooth yield ancient DNA?

Publication: msnbc.com   Date: January 11, 2011   View Article

Scientists are gearing up to use a new drilling technique to extract ancient DNA from an 18,000-year-old tooth that belonged to a “hobbit,” the mysterious, diminutive creatures that once lived on the Indonesian island of Flores.

If successful, a comparison of the DNA with other species could help resolve disputes surrounding who the hobbits were and where they originated.

Ten fossils that evolved the tale of our origins

Where did we come from? Many truth seekers turn to faith and religion and therein find their answers. Others approach the question through a scientific lens and the theory of evolution. They have pieced together a tale of human origins from the fossils of our ancestors. The tale is incomplete and its telling reshaped with fresh interpretation of the growing fossil record.

Neanderthals living in a pair of caves on the Mediterranean Sea regularly feasted on mussels, fish, and other types of marine life, according to a new study.

The finding suggests that Neanderthals actively foraged for seafood just like early modern humans, according to Clive Finlayson, an anthropologist at the Gibraltar Museum.

Massive Genetic Study Supports “Out of Africa” Theory

A massive new study of human genetic diversity reveals surprising insights into our species’ evolution and migrations—including support for the theory that the first modern humans originated in Africa—scientists said today.

Researchers compared 650,000 genetic markers in nearly a thousand individuals from 51 populations around the globe—an unprecedented level of detail for a human genetic study.

An early modern human from China dated to about 40,000 years ago adds to evidence that the first Homo sapiens sapiens occasionally mated with older human species such as Neandertals.

The remains—which represent the oldest known example of modern humans found in China—share a few characteristics with older human species, according to a new study.
