For the first time, scientists have reconstructed the ancient genomes of human betaherpesvirus 6A and 6B (HHV-6A/B) from ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...

Scientists estimate that the earliest biological entities began to appear on Earth more than 4 billion years ago. "There was a sort of primordial soup from which certain organic molecules were formed.

Retroviruses - the family of viruses that includes HIV - are almost half a billion years old, according to new research by scientists at Oxford University. That's several hundred million years older ...

Researchers studying the evolutionary dynamics of bacteria and viruses in bubbling glass tubes have confirmed an evolutionary theory of central importance to ecologists studying more familiar flora ...

In 2003, Acanthamoeba polyphaga mimivirus, also known as mimivirus, was the first giant virus to be described. It's larger than many bacteria, and was found in a water sample from a hospital cooling ...

When the virus that caused the COVID-19 pandemic first emerged, many scientists thought it would evolve slowly, like other coronaviruses. But that was one of the first big surprises from the virus ...
