Article: Research on evolution reported by scientists at Kalamazoo College.

According to recent research published in the journal Evolution & Development, "We have cloned and analyzed two Emx genes from the lamprey Petromyzon marinus and our findings provide insight into the patterns and developmental consequences of gene duplications during early vertebrate evolution. The Emx gene family presents an excellent case for addressing these issues as gnathostome vertebrates possess two or three Emx paralogs that are highly pleiotropic, functioning in or being expressed during the development of several vertebrate synapomorphies."

"Lampreys are the most primitive extant vertebrates and characterization of their development and genomic ...
