Using cutting-edge DNA sequencing technologies, a group of laboratories in Konstanz, Würzburg, Hamburg and Vienna, led by evolutionary biologist Professor Axel Meyer from the University of Konstanz, have fully sequenced the genome of the Australian lungfish. The genome, with a total size of more than 43 billion DNA building blocks, is nearly 14 times larger than that of humans and the largest animal genome sequenced to date. Its analysis provides valuable insights into the genetic and developmental evolutionary innovations that made it possible for fish to colonize land. The findings, published online in the journal Nature, expand our understanding of this major evolutionary transition in the Devonian ~420 million years ago.
