Supercluster F appeared around 50,000 years ago and is the most common macro-haplogroup outside of Africa with more than 90% of the world’s population.The DNA of modern Turkish people suggests that a human expansion occurred from 50,000 years ago in the Middle East, through Anatolia, and finally to the rest of Europe.Unexpectedly, their analyses showed three major lineages of modern frogs—about 88 percent of living species—appeared simultaneously, evolving on the heels of the extinction event that marked the end of the Cretaceous Period and the beginning of the Paleogene 66 million years ago.Previous research suggested a more ancient origin of many of these modern frog groups.They say, if this was true, my Teachers and Professors would have taught it to me.
The fact is that European scientists had evidence, and knew from earlier that the 19th century, of the Black mans central role in settling and establishing civilization in Europe and everywhere else.A 2009 study on African genetics located the origin of modern human migration in south-western Africa, near the coastal border of Namibia and Angola.The site is the homeland of the indigenous San people."We think there were massive alterations of ecosystems at that time, including widespread destruction of forests," he said."But frogs are pretty good at eking out a living in microhabitats, and as forests and tropical ecosystems rebounded, they quickly took advantage of those new ecological opportunities." Frogs rose to become one of the most diverse groups of vertebrates, with more than 6,700 described species.
