Seeing with your eyes is sooo old school.. echolocation is where it's at! This super useful form of sight allows animals like dolphins and bats to navigate all kinds of places. So how did these animals grow to develop sonar and how does a biologically-based sonar system work? Anthony is joined by Animalist host Alex Farnham to explain.

Most people's immediate answer would be "not a lot." However, a group of researchers have recently sought to investigate the genetic profiles of these two unrelated species, based upon a single similarity in their behavior."
Genome-wide signatures of convergent evolution in echolocating mammals http://www.nature.com/nature/journal/vaop/ncurrent/full/nature12511.html "Echolocation is a complex phenotypic trait that has evolved independently in bats and whales, and which involves the production, reception and auditory processing of ultrasonic pulses for obstacle avoidance, orientation and hunting."
Queen Mary scientists uncover genetic similarities between bats and dolphins http://www.qmul.ac.uk/media/news/items/se/113396.html "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, according to new research led by scientists at Queen Mary University of London and published in Nature this week."
