A vast stretch of islands across the South Pacific holds one of the oldest human stories on Earth. For tens of thousands of ...

A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents ...

Stanford researchers have gained new insights into how the rise of reproductive barriers between organisms creates new species and drives the incredible diversification of life on Earth. One major way ...

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 ...

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 ...

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants ...

The human genome is a rich, complex record of migration, encounters, and inheritance written over thousands of millennia. In this month of love, amid the exchange of flowers and cards, genomic ...

Filamentous fungi exhibit a remarkable capacity to coordinate genetic activity across expansive, multinucleate networks of hyphae. Genetic interactions in these organisms encompass heterokaryosis—the ...

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 ...
