Bacterial resistance to antibiotics is a growing health threat, but its evolution outside laboratory settings is poorly understood. Bacteria living in the human gut are now found to evolve persistent ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Playing a complex guitar solo ought to be impossible. To elicit the desired torrent of notes, the fingers of one hand must move nimbly around the fretboard, while the other hand plucks the strings, in ...
