The origins of projectile weaponry - Sigma Xi pizza lunch

From Sigma Xi:

We'll reconvene at noon, Tuesday, Oct. 20, at Sigma Xi, the Scientific Research Society, with a peek at one of the many ways technology helped our species survive and prosper long ago.

Steven Churchill, an associate professor of evolutionary anthropology at Duke University, will discuss the origins of projectile weaponry, and how that fit with the emergence of other aspects of modern human behavior. He'll talk about his fascinating forensics work exploring ways our ancestors may have used weapons against evolutionary cousins who no longer roam this planet.

American Scientist Pizza Lunch is free and open to science journalists and science communicators of all stripes. Feel free to forward this message to anyone who might want to attend. RSVPs are required (for a reliable slice count) to cclabby@amsci.org
