Archaeology
- The Possibility that Meteorite Impacts may have Affected Northern
Paleolithic
Populations is the Topic of Lecture Series in Santa Fe: Truly
revolutionary
ideas are not very common these days, but one is peeking up above the
horizon of
North American prehistory. Dr. Richard Firestone, an isotope physicist
from the
Lawrence Berkeley Laboratory, has uncovered evidence for cosmic collisions
at
times that would have influenced humans and their environment. Impacts at
39,000
and 12,900 years ago devastated portions of the northern hemisphere,
treating
the ice-age megafauna to smaller versions of the type of shock that
contributed
to the extinction of the dinosaurs. The 12,900 BP impact may have changed
the
course of the cultural as well as natural history of North America, and
the
possibility is challenging accepted views of Paleoindian archaeology.
