Evolution Under a Microscope
Evolution in humans takes thousands of years but, in bacteria, the changes can come more quickly. It’s the changes that occur in the reproduction of Escherichia coli bacteria that Joan Slonczewski, professor of biology, is studying with her nearly $500,000 grant from the National Science Foundation. The project explores how E. coli, a bacteria commonly found in the digestive tract of warm-blooded animals, reacts to extreme pH levels. Slonczewski and the students working with her have watched the…
