From regulating each other’s gene expression to encoding different parts of the same proteins, the two genome types in every eukaryotic cell are far from independent.

Interactions between mitochondrial and nuclear genomes have further-reaching effects on physiological function, adaptation, and speciation than previously appreciated.

When different archaeal species mate, their CRISPR systems interact in ways that may influence their evolution.

A fish created by spontaneous androgenesis is the first known vertebrate to arise naturally by this asexual reproductive phenomenon. 

Speciation and development of new traits may not always go hand-in-hand.

Standard taxonomy lumps together bird species that should be separate, a new study suggests, raising the total number of estimated species from 9,000 to 18,000.

Rick Harrison, an evolutionary biologist known for his research on speciation, has passed away at age 70.

Scientists mutate a mating pheromone and its corresponding receptor in yeast to promote speciation.

New hadrosaur uncovered in Utah hints at surprising speciation.
