In the second part of talk, I explore other clues that suggest that genomes are not at equilibrium. Some genes appear to be changing more slowly and these older "fossil" genes in modern day genomes may give us insight into the distant past. I also hope to convince you that many of the great mysteries in contemporary biology do not require big research labs but can be solved through "home genomics"- piecing together information through a computer, the internet, and an inquisitive mind.

What Genomes Can Tell Us About the Past by Sydney Brenner - Part 1: (39:06)

By looking at the light from distant galaxies and having well-established calibration methods, astrophysics can make hypotheses about the history of our universe. Do we have similar "rulers" in biology that could allow us to reconstruct the remote past and the evolution of species on this planet? The answer is likely "yes" and the clues are undoubtedly contained in the many whole genome sequences that are now available for inspection. However, it is critical to evaluate the assumptions that...
