How interspecies competition led to a 'bizarre' pattern in our own evolutionary tree

Competition between species played a major role in the rise and fall of hominins—and produced a "bizarre" evolutionary pattern for the Homo lineage—according to a new University of Cambridge study that revises the start ...

Study highlights urgency of parasitic wasp release to save native bird

Researchers with the University of Minnesota hope to release highly specialized parasitic wasps to serve as a biological control method to save Darwin's finches from a dire threat: the invasive avian vampire fly, Philornis ...
