The Ames Test

In 1973 biochemist Bruce Ames created a simple test that showed if chemicals had the potential to cause cancer. The Ames test made him a hero of the emerging environmental movement. But then he completely changed course and said concerns about chemicals were overblown. So what happened? Did Ames change? Or did our understanding of what causes cancer change?
