Mutation, recombination, and incipient speciation of bacteria in the laboratory.

Proceedings of the National Academy of Sciences of the United States of America - 22 Jun 1999

Vulić M, Lenski R E, Radman M

Abstract excerpt

Mutations in the DNA mismatch repair system increase mutation and recombination. They may thereby promote the genetic divergence that underlies speciation, after which the reacquisition of a functional repair system may sustain that divergence by creating a barrier to recombination. We tested several lines of Escherichia coli, derived from a common ancestor and evolved for 20,000 generations, for their...
