Tracking the myxoma virus in the wild rabbit populations of Australia has yielded insight into how pathogens and their hosts evolve.

Biologists’ walk in the woods sparks the creation of a masterful fruit fly field guide. 

A genomic analysis of “Klosneuviruses” suggests that they evolved from small viruses that accumulated genetic material over time, but not all virologists are convinced. 

Researchers discover that short pieces of DNA harboring oncogenes are relatively widespread in cancer.

The emergence of blood abnormalities, an adult ability to digest milk, and changes in our physical appearance point to the continued evolution of the human race.
