Gene activity is linked to songbirds’ tunes.

Watch soldier ants behave more like foragers after scientists change their gene expression.

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

An analysis of more than 400 human genomes from residents of 13 African countries presented at this week’s annual meeting of the American Society of Human Genetics greatly expands our species’ cataloged genetic diversity.

A genomic analysis from 23andMe suggests that people inherit two copies of a chromosome from only one parent nearly twice as often as researchers had realized.

Despite a solid understanding of the biological basis of fragile X syndrome, researchers have struggled to develop effective treatments.

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.

Variation in the number of CGG repeats in the FMR1 gene at the bottom of the X chromosome can lead to increased levels of mRNA or decreased levels of protein—both conditions that cause disease.
