A new study of the genes of the widely known as non-usable cockroaches showed that their last common ancestor lived sometime during the Triassic period. This supports the hypothesis that they have taken their global domination by dividing the supercontinent on the continents we know today, though they did not look much like today. And, let's face it, if there is one thing that unites all people on earth, that's their general disgust at the cockroaches. But the truth is that we have to give them what they deserve and acknowledge things that are not found in many species.
It turns out that cockroaches have been an ubiquitous phenomenon for so long that, to spread globally, they did not even have to shake with wings: they only had to wait for the continents to separate, and they were literally all over the earth. A team of scientists took samples of 119 species of live cockroaches to assess how long their evolution was. "Our results have shown that today's families of cockroaches have evolved for about 180 million years," explains Thomas Burgieon of the Institute of Science and Technology in Japan. 235 million years ago when the common ancestor of all cockroaches lived, the land was much different than today: the days were shorter, the climate warmer, and all the continents were part of a giant piece of land called Pangea .
