genomes divergences during metazoan evolution

albeit being not  dino-related, i thought this could be of some interest to 
some DMLers

Abstract
Seven distinct genome-wide divergence measures were applied pairwise to the 
nine sequenced animal genomes of human, mouse, rat, chicken, pufferfish, fruit 
fly, mosquito, and two nematode worms (Caenorhabditis briggsae and 
Caenorhabditis elegans). Qualitatively, all of these divergence measures are 
found to correlate with the estimated time since speciation; however, marked 
deviations are observed in a few lineages. The distinct genome divergence 
measures also correlate well among themselves, indicating that most of the 
processes shaping genomes are dominated by neutral events. The deviations from 
the clock-like scenario in some lineages are observed consistently by several 
measures, implicitly confirming their reliability.
