Previous models of self-incompatibility accounted for only one-to-one interactions between male and female-determinant proteins. The new model allows for a more general network of interactions, where ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

New research suggests a genetic dynamic that may have contributed to Neanderthals' extinction. Neanderthal-Museum, Mettmann CC BY-SA 4.0 via Wikimedia Commons Did interbreeding between humans and ...

Justin Havird, Erik Iverson and their colleagues have identified genes involved in hybrid incompatibility in swordtail fishes. The sheepshead swordtail fish (Xiphophorus birchmanni). Photo credit: Dan ...

Self-incompatibility (SI) is a sophisticated reproductive strategy that prevents self-fertilisation and maintains genetic variability in flowering plants. This mechanism involves highly specific ...

Plants, with their unique immune systems, sometimes launch 'autoimmune responses' by mistakenly identifying their own protein structures as pathogens. In particular, 'hybrid necrosis,' a phenomenon ...

The human genome is a complex record of migration, evolution, and ancestry written over thousands of millennia. Now, new genomic research by members of Sarah Tishkoff’s lab at the University of ...
