Lizard genome sequence solves a human genetic mystery

Lizard genome sequence solves a human genetic mystery – io9

The interesting finding is that a number of non-coding regions of human DNA correspond to active transposons (“jumping genes”) in the lizard DNA.

Another surprise is that the lizards have essentially the same sex chromosomes as mammals – unlike birds.

320 million years ago, mammals and reptiles reached an evolutionary parting of the ways. We’ve now sequenced a lizard genome for the first time ever, and it’s vastly different from our own…but in a few crucial ways, it’s shockingly similar.
