Scientists have discovered a 50,000-year-old herpes virus

Revolutionary ancient DNA evidence indicates that Homo sapiens finished off Neanderthals through deadly infectious diseases

Less than a decade ago, the American anthropologist James C Scott described infectious diseases as the “loudest silence” in the prehistoric archaeological record. Epidemics must have devastated human societies in the distant past and changed the course of history, but, Scott lamented, the artefacts left behind reveal nothing about them.

Over the last few years, the silence has been shattered by pioneering research that analyses microbial DNA extracted from very old human skeletons. The latest example of this is a groundbreaking study that identified three viruses in 50,000-year-old Neanderthal bones. These pathogens still afflict modern humans: adenovirus, herpesvirus and papillomavirus cause the common cold, cold sores, and genital warts and cancer, respectively. The discovery may help us resolve the greatest mystery of the Palaeolithic era: what caused the extinction of Neanderthals.
