Becoming Human

The fossil evidence has long indicated there were two great migrations out of Africa.

Early Craftsmanship, to the right of this column, is a new feature on BecomingHuman. This 18-minute video is an introduction to humankind's first surviving technology, demonstrates how stone tools were made and looks at how this technology became more complex.

Stone tools played an important role in human evolution and one of the most significant stone technologies was the Acheulean, distinguished by the tools' characteristic tear drop and oval shaped handaxes. This technology, named for the place in France where some of the first examples were found in the 19th century, was thought to have originated around 1.4 million years ago (ma).

A summary article in Science this week asks this question, after revealing the results of another study of ancient eating habits, and in general revisits the many questions connected with this much debated ancestor.

The New York Times, citing a paper in Nature,  reported last week “Researchers studying the diet of human ancestors who lived two million years ago in southern Africa have unexpectedly come across a crucial clue to their social structure. The males never strayed far from home, and the females dispersed after puberty to neighboring groups”

Neanderthals were back in the news last week. But then, Neanderthals are seldom out of the news and have not ceased to fascinate us since they were discovered and named about 150 years ago.

Two renowned fossil hunters, once rivals, met before an appreciative audience in New York last week and discussed the significance of their finds and the importance of increased public understanding of evolution.

The New York Times'Science section for March 15, 2011 offers readers a variety of articles on the human condition and how we became human.  Starting with cells, these articles explore human evolution and our relationships with other living things, including our pets.

A small, three million year old bone found ten years ago and recently analyzed is helping to resolve an important question and illustrates how exacting science is done.
