What Makes us Different?
Posted by tom | Oct 2, 2006Not very much, when you look at our DNA. But those few tiny changes made all the difference in the world This frontpage Time Magazine piece concludes: For most of us, though, it's the grand question about what it is that makes us human that renders comparative genome studies so compelling. As scientists keep reminding us, evolution is a random process in which haphazard genetic changes interact with random environmental conditions to produce an organism somehow fitter than its fellows. After 3.5 billion years of such randomness, a creature emerged that could ponder its own origins--and revel in a Mozart adagio. Within a few short years, we may finally understand precisely when and how that happened.
Sorry. I don't find the continual retelling of the random process creation myth and our ability to pinpoint the significant events in this process compelling. Looking forward to what Justin Barrett has to say in a few weeks.
