Yesterday’s SciTechStory post on the topic of the male Y-chromosome was one of many in the blogosphere. That´s hardly unexpected–sex, males, chimps–some built-in interest there. One post in particular at The Atavism is well worth a read-through. The post is at The why of the Y-Chromosomes amazing evolutionary rate. Here’s a sample:
It’s evident that, far from being in the tail end of an inexorable decline, the Y-chromosome is evolving a good deal more quickly than the rest of the genome. So, the burning question is what is behind that evolutionary rate? There is probably no single answer to that question but it’s safe to assume it results from some of the unique features of the Y-chromosome; a lack of genetic recombination, the presence of those large repetitive sections of DNA and the preponderance of male specific genes.
