Evolution depends on rare chance events, 'molecular time travel' experiments show
June 19, 2014
While historians can only speculate on what might have been, a team of evolutionary biologists studying ancient proteins has turned speculation into experiment. They resurrected an ancient ancestor of an important human protein as it existed hundreds of millions of years ago and then used biochemical methods to generate and characterize a huge number of alternative histories that could have ensued from that ancient starting point.
