Vincent Stannus joins the lab to conduct his Senior Research Project on within-species morphometric transformations of avian eggs. Vince is the fifth Tucson/Oro Valley high school senior to conduct his senior research in the lab.
In a new J. Evol. Biol.paper we show that subsampling of preexisting biochemical network is a dominant mode of avian carotenoid evolution over the last 50 million years. The discovery empirically illustrates a fundamental requirement of organismal evolution – historical continuity of past and present functional associations.

For evolution to proceed, the maintenance of a currently adaptive configuration of traits must not preclude the incorporation of innovation in the same traits. In a new paper we propose and test a novel mechanistic principle that clarifies how local adaptation can be reconciled with continuity of evolution.
