Theorists Debate How ‘Neutral’ Evolution Really Is

November 8, 2018

For 50 years, evolutionary theory has emphasized the importance of neutral mutations rather than adaptive ones at the level of DNA. Real genomic data challenges that assumption.

‘Broadband’ Networks of Viruses May Help Bacteria Evolve Faster

October 16, 2018

A newly discovered mechanism may enable viruses to shuttle genes between bacteria 1,000 times as often as was thought — making them a major force in those cells’ evolution.
