Evidence: How Do We Know What We Know?
Alfred Wegener's Crazy Idea (Podcast)
Date: August 20, 2008
An interview with Mel Zucker, Professor of Geology, Skyline College, San Bruno, California.

In the early 1900s, German meteorologist Alfred Wegener suggested that the earth's continents were once a single landmass that had somehow split into pieces, drifting their separate ways. Geologists the world over called his idea preposterous. Decades later, their ridicule shifted to admiration as new tools developed by the military to map the ocean floors revealed the engine that drives the continents' movement. Geology professor Mel Zucker tells the story of this brilliant earth scientist and how, long after his death, science finally caught up with Wegener's crazy idea.
In these videos, scientists at the Max Planck Institute for Evolutionary Anthropology present evidence from a variety of scientific disciplines that helps us understand human origins.
