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.

The Yale biologist says that organisms’ behavior, physiology, and morphology engage in a constant “evolutionary dance.”

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

A new study finds mixtures of nucleotide types, rather than pure systems, are more likely to yield the building blocks of life.

From skin color to immunity, human biology is linked to our archaic ancestry.

See when and where our ancestors may have interbred with Neanderthals and Denisovans.

Theodosius Dobzhansky’s work in population genetics influenced how genetics and natural selection were combined in evolutionary biology.

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes.

Thicker calluses don’t dull sensitivity in feet.
