“Living fossil” genome sequence reveals clues to evolution of life on land


Genome sequencing can teach us a huge amount about a species, and now scientists have completed the sequence for one of the weirdest and most intriguing animals in the world. The Australian lungfish is a “living fossil” from the time our ancestors first crawled out of the oceans, and its genome reveals that it’s our closest living fish relative and it has the largest genome of any animal sequenced so far.
The Australian lungfish is one of six lungfish species in the world, and it’s a bizarre creature. As the name suggests, it has a lung in its back that lets it breathe air, and it can “walk”
