Are Europeans Today Genetically Different from Their Ancestors?

Different ethnic groups have shaped the genetic makeup of today’s Europeans. Through migration from various regions of the world, the genetic material of humans who first arrived in Europe forty thousand years ago has seen drastic changes over the last ten thousand years. By analyzing D.N.A extracted from ancient bones, JOHANNES KRAUSE traces back the genetic ancestry of human beings, especially those living in Europe today. He explains in this video that, using recently developed D.N.A sequencing technologies, the research proves that genetic shifts happened about eight thousand as well as five thousand years ago. These findings correlate with the knowledge of archeologists that cultural changes, such as changes in subsistence strategies, occurred at the same time due to migration. The research presented shows that cultural changes and genetic changes sometimes went hand in hand
