We all know Homo sapiens evolved in Africa and then spread across the rest of the world. But scientists have demonstrated that, starting around 5000 B.C.E., an astoundingly large group came back. This “backflow” brought so many people from Eurasia that today’s East Africans get as much as 25% of their genome from Middle Eastern ancestors. In other words, about a quarter of their ancestors were Middle Eastern migrants. And even in southern Africa, thousands of miles away, the people get about 5% of their genes from backflow migrants. In fact, the Khoe-San of southern Africa get some of their pale skin genes — an advantage in sun-poor lands far from the equator — from these Eurasians. Continue reading “The Backflow into Africa”
This week marks the traditional reckoning date for the fall of Troy, in 1183 B.C. The ancient Greeks calculated the date centuries later, but they probably weren’t far off. Whatever the timing, Troy offers a frightening warning for our world in 2020. Continue reading “The Fall of Troy and Its Warning for 2020”
A virus circles the world, killing 1% of the population or more, particularly the elderly … and people just go about their business. Even in countries that understand contagion, no one healthy stops working, and neither do most of the sick. In fact, if you suggest staying home, most people think you’re crazy. Why manufacture an economic disaster? That’s how our ancestors would react to coronavirus, from the ancient world through early modern times. Their lives already involved a steady risk of death from acute, fast-acting disease, so this comparatively mild new illness would hardly set them back.

Many Americans doubt man-made global warming because they don’t think humans could so fundamentally change the world. Some believe only God could alter the climate. But small groups of Homo sapiens have been re-engineering the environment on a massive scale for thousands of years, using only primitive tools. Many scientist think that includes ancient man-made global warming.
Most of us know that humans have been cutting down forests and wiping out animal species for millennia. But we rarely recognize the scale of past people’s impact Continue reading “Ancient Man-Made Global Warming and Environmental Engineering”
The legend of Atlantis comes from Plato. In Timaeus and particularly Critias, written around 360 B.C., the Greek philosopher describes an island society ruling a great empire. But the Atlanteans’ pride angers the gods, who destroy the island with floods and earthquakes, sending it beneath the sea. Continue reading “The Real Destruction of Atlantis”
