The evolution of similar traits in different species, a process known as convergent evolution, is widespread not only physically but also at the genetic level, according to a new study led by scientists at Queen Mary University of London, in the UK, and published in this week’s edition of the journal Nature. These experts have found genetic similarities between bats and dolphins.
Scientists investigated the genomic basis for echolocation or echolocation, one of the best known examples of convergent evolution to examine the frequency of the process to a genomic level. Echolocation is a complex physical trait that involves the production, processing, receiving and hearing ultrasonic pulses to detect unseen obstacles or tracking prey and evolved separately in different groups of bats and whales .
