Squid, octopus and cuttlefish have scrambled-up genomes that may help explain how these cephalopods evolved the most complicated nervous systems of any invertebrate.

 

New genetic sequencing reveals that these animals' genes are mixed up, arranged in strange orders not seen in other, non-cephalopod species. This DNA mixing and matching may have given evolution a new sandbox to play in, study co-author Caroline Albertin, a biologist at the University of Chicago Marine Biological Laboratory, told Live Science.
