Millions of years before humans invented sonar, bats and toothed whales had mastered the biological version of the same trick – echolocation. By timing the echoes of their calls, one group effortlessly flies through the darkest of skies and the other swims through the murkiest of waters. It’s amazing enough that two such different groups of mammals should have evolved the same trick but that similarity isn’t just skin deep.
this is exciting and amazing stuff. Whales and bats share the same genetic make up for echolocation? who knew this?


Another notch for evolution. It’s something like <50% max difference between any two given species ever on this planet.
