CAREFREE, ARIZ.—What does it mean to be human? A panel of anthropologists at the inaugural Origins Symposium organized by Arizona State University yesterday presented several perspectives—from genetic to cultural to environmental—on where and how the birth of our species occurred.
The weekend meeting brings together 70 leading scientists, including eight Nobel laureates, in origins studies across all disciplines, to explore major questions in their fields. Live webcasts continue today; presentations open to the public will follow on Monday.
Anthropologist Alan Rodgers of the University of Utah spoke of the new insights from genetics and how fast-evolving areas of the human genome provided new traits, such as the ability to digest milk into adulthood, contributed to survival success. “Current evidence suggests that we are a rapidly evolving species,” he added. “We have changed a lot in a few tens of thousands of years.” (An upcoming report from Scientific American will detail many of these changing regions.)

TEMPE—The first annual Origins Symposium at Arizona State University here began yesterday with a bang—a big bang, that is—as a panel outlined the theoretical and technical challenges of peering still closer to that signal event in the history of the cosmos for clues about the nature and evolution of the universe we know today.
The weekend meeting pulls together experts, including several Nobel laureates, in origins studies across all disciplines, from those concerned with outer space to the inner space of human consciousness; public presentations will follow on Monday.
“There’s only so far back we can see, and that’s about 380,000 years” after the big bang, when detection of light particles, or photons, becomes impossible because of the high energies at that time, said physicist Michael S. Turner of the University of Chicago, who moderated the panel. “Within Einstein’s theory of general relativity, the big bang is a singularity—we can’t go beyond that singularity.” He outlined five key problems to getting closer to that instant:
