“It’s simply too harsh even for the toughest hunter-gatherers.” But about 15,000 to 9,000 years ago—after the so-called last glacial maximum (LGM), during which the Earth’s ice cover had reached its most extensive point and climate was at its harshest—people flocked into Tibet en masse.“It’s the most significant wave of migration that shaped the modern Tibetan gene pool,” Xu says.Product datasheet Upgrade Price Guarantee Compatible with Windows 10, 8.1, 8, 7, Vista and XP, 32 Bit / 64 Bit Editions New language versions: Chinese - Lithuanian - Japanese - Polski - Romanian - Spanish - Czech Update Star is compatible with Windows platforms.Update Star has been tested to meet all of the technical requirements to be compatible with Windows 10, 8.1, Windows 8, Windows 7, Windows Vista, Windows Server 2003, 2008, and Windows XP, 32 bit and 64 bit editions.Wild Cat 666 – Mega Pack (MDH) Mydirtyhobby is the world’s biggest community for private erotica made at home.

The first humans venturing onto the Tibetan Plateau, often called the “roof of the world,” faced one of the most brutal environments our species can endure.
At an average elevation of over 4,500 meters, it is a cold and arid place with half the oxygen present at sea level.
Science has long held that humans did not set foot in this alien place until 15,000 years ago, as suggested by archaeological evidence of the earliest known settlement on the northeastern fringe of the plateau 3,000 meters above sea level.
But now new genetic data indicate this may have occurred much earlier—possibly as far back as the last ice age, 62,000 years ago.“Tibetan-specific DNA sequences can be traced back to ancestors 62,000-38,000 years ago…This represents the earliest colonization of the Tibetan Plateau,” says Shuhua Xu, a population geneticist at the Chinese Institute of Sciences’ Shanghai Institutes for Biological Sciences.
