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 and end dates for many of our early ancestors.

Researchers identify genetic variant that helped shape human skull base evolution

Humans, Homo sapiens, have unique features compared with other closely related hominin species and primates, including the shape of the base of the skull. The evolutionary changes underlying these features were significant in allowing the evolution of our increased brain size.

Discovery of bacterial proteins that induce asexual reproduction in insects

From microbes in the human gut to symbiotic algae in coral reefs, research in recent decades has increasingly revealed the pivotal roles that microorganisms (or microbial species) play in shaping the biology of host organisms and of broader ecosystems. For example, some endosymbionts—microbes that live within the cells of a host organism—are known to manipulate the physiology of their hosts to promote their own persistence from generation to generation.
