Genomes, Evolution, and the K-T Boundary

Adaptive Complexity's Michael White points out a new journal, called Genome Biology and Evolution. The journal editors say in an introduction that "advances in genomic technologies are revolutionizing our perspectives on evolution once again" and that "GBE aims to nurture the highest standard of evolutionary genomic research, with the help of the molecular evolutionary and population genetic expertise." White also says to take a look at one of the journal's first papers, from Indiana University's Michael Lynch. That paper says that there were "widespread reductions in genome size" in mammalian lineages after the Cretaceous–Tertiary boundary, though "there is no evidence for such changes in other vertebrate, invertebrate, or land plant lineage."
