Yellow River sedimentary evidence dates the Great Flood of China, and the start of the Xia dynasty, at 1920 BCE

The earliest historical records of Yu start only about 1,000 years after his death. It was thought that Yu lived around 2,200 BCE. A new paper in Science reports on studies of Yellow River sediments and suggest that the cause of the flood was a landslide, caused by an earthquake, that planted a massive natural dam across the Yellow River where it travels through the Jishi Gorge after emerging from the Tibetan plateau.

When humans were prey for hyenas

Human ancestors had rudimentary control of fire some 1.5 – 2 million years ago, and that was the single event that led to the inevitable journey to becoming the dominant species.

A new paper shows that tooth marks on the bones of a 500,000 year old hominin were caused by a large carnivore and indicating that the hominin had been consumed. Continue reading

Our Neanderthal genes may have come mainly from their females

So I imagine the decline of the Neanderthals taking some 20-30,000 years as AMH expanded westwards and the decline of the Denisovans probably starting a little later but taking somewhat less time. The encounters and admixing probably only occurred with the tribes and bands at the frontiers. Continue reading

Scavenging came long before hunting

So the timeline I envisage for the development of human activity takes us from foraging to scavenging to hunting to herding to transient agriculture and finally to settled agriculture. Continue reading
