Bats And Dolphins Share Echolocation Genetics
New research from Queen Mary University in London is looking at the genetic basis for echolocation, which has developed separately in a variety of animals including bats and dolphins. Researchers were specifically looking at echolocation evolution on the genetic level and, by comparing genomic sequences, they found similar genetic signatures in nearly 200 different genomic regions concentrated in several “hearing genes.” They had expected to find identical changes in a dozen or so genes in these totally unrelated animals, but were super excited to see nearly 200. Researchers say this is a great example of convergent evolution —the evolution of similar traits in drastically different types of creatures.
