Many genes in dolphins and bats evolved in the same way to allow echolocation

Widespread changes scattered across the genomes of distantly related species crafted the trait

Despite being separated by millions of years of evolution, dozens of genes in dolphins and bats changed in the same manner to give the species their ability to echolocate. A study, which has received criticism from some scientists, found that similar mutations allowed webs of genes in the animals to contribute to the superpower of being able to “see” with sound.


Biologists have long been interested in convergent evolution, the process by which distantly related species develop similar traits....
