Cockroach ancient geographic and genomic history traced back to last supercontinent

(Molecular Biology and Evolution (Oxford University Press)) Armed with a vast amount of genomic information, a team of researchers led by Dr. Thomas Bourguignon, now professor at the Okinawa Institute of Science and Technology, has performed the first molecular dating to gain the clearest picture yet of the biogeographical history of cockroaches. They have traced back the key evolutionary time points of the cockroach -- all the way back almost 300 million years ago when the Earth's mass was organized into the Pangaea supercontinent.
