This is what happened with E. coli bacteria. They were studied over 15, 000 generations. The study looked at changes in the bacteria's RNA polymerase. This is a key part ...

When Bacteria Began: Decoding the Past with Ancient Alliances

Scientists have found a new way to solve this puzzle by looking at ancient partnerships between bacteria and other life forms. They used genes found in mitochondria–the tiny powerhouses inside our cells that were once bacteria–to create a family tree of bacte...
