Right-handedness prevailed 500,000 years ago

1000pa (Apr. 20, 2011) — Right-handedness is a distinctively human characteristic, with right-handers outnumbering lefties nine-to-one. But how far back does right-handedness reach in the human story? Researchers have tried to determine the answer by looking at ancient tools, prehistoric art and human bones, but the results have not been definitive.

Now, David Frayer, professor of anthropology at the University of Kansas, has used markings...

  • PDF
1000pa (Apr. 13, 2011) — The long-held theory that early human ancestors in East Asia crafted their tools from bamboo and wood is much more complicated than originally conceived, according to a new study. Research until now has failed to address a fundamental question: Is it even possible to make complex bamboo tools with simple stone tools?

Now an experimental archaeological study -- in which a modern-day flint knapper replicated the...

Anthropologists link human uniqueness to hunter-gatherer group structure

  • PDF
1000pa (Mar. 11, 2011) — One of the most complex human mysteries involves how and why we became an outlier species in terms of biological success.

Research findings published in the March 11 edition of the journal Science by an international team of noted anthropologists, including several from Arizona State University, who study hunter-gatherer societies, are informing the issue by suggesting that human ancestral social structure may be...

1000pa (Feb. 24, 2011) — Scientists have discovered the cremated skeleton of a Paleoindian child in the remains of an 11,500-year-old house in central Alaska. The findings reveal a slice of domestic life that has been missing from the record of the region's early people, who were among the first to colonize the Americas.

The discovery, by Ben Potter of the University of Alaska Fairbanks and colleagues, appears in the 25 February issue of...
