This Week in Nature

In Nature this week, a team from Queen Mary University reports on research indicating that convergent evolution — the process by which similar traits appear in different species — is widespread at the genetic level. They studied the rise of echolocation, which is present species ranging from bats to dolphins, comparing the genomes of 22 mammals, including ones with the ultrasonic ability, and found genetic signatures consistent with convergence in nearly 200 genomic regions.
