A Phylostratigraphy Approach to Uncover the Genomic History of Major Adaptations in Metazoan Lineages

Trends Genet. 2007 Nov;23(11):533-9. doi: 10.1016/j.tig.2007.08.014.

Abstract

Macroevolutionary trends traditionally are studied by fossil analysis, comparative morphology or evo-devo approaches. With the availability of genome sequences and associated data from an increasing diversity of taxa, it is now possible to add an additional level of analysis: genomic phylostratigraphy. As an example of this approach, we use a phylogenetic framework and embryo expression data from Drosophila to show that grouping genes by their phylogenetic origin can uncover footprints of important adaptive events in evolution.
