Echolocation's Convergent Evolution: Genetic Similarities Between Bats And Dolphins

The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only at the physical level, but also at the genetic level, and scientists who investigated the genomic basis for echolocation, one of the most well-known examples of convergent evolution, sought to examine the frequency of the process at a genomic level.  Echolocation is a complex physical trait that involves the production, reception and auditory processing of ultrasonic pulses for detecting unseen obstacles or tracking down prey, and has evolved separately in different groups of bats and cetaceans (including dolphins). read more
