Ancient virus in chimp DNA disables a human-active gene

Original: An ancient virus in chimpanzee DNA switches off a gene that is active in humans

Researchers report that an ancient virus embedded in chimpanzee DNA switches off a gene that remains active in humans. The finding offers a fresh example of how viral remnants embedded in the genome over millions of years have shaped differences between species, and it may deepen understanding of the genetic gulf separating humans from our closest living relatives.

Why now: The discovery highlights how ancient viral DNA contributed to genetic differences between humans and chimpanzees, a topic of broad scientific interest.
