Neanderthals seem to have become permanently separated from their kin when the ice sheets grew about 300 kya, and between 250 kya and 200 kya two glacial events happened, which roughly coincided with the final exit of and the appearance of either or that . The previous interglacial period began 130 kya and ended 114 kya, and it appears that left Africa for the first time about then; evidence is , and they may have traveled much farther. When ice sheets advanced, Neanderthals retreated southward, and one controversial area is the overlap of Neanderthals and in Israel during that interglacial period. Did Neanderthals wipe out those first migrants from Africa? Did they interbreed?
This essay presents a , and nearly half of the events happened during the timeframe covered by this essay's first half, which includes almost the entirety of Earth's history. Humanity's tenure amounts to a tiny sliver of Earth's history, and surveying pre-human events was partly intended to help readers develop a sense of perspective. We are merely Earth's latest tenants. We have unprecedented dominance, but we are quickly destroying Earth's ability to host complex life. As my astronaut colleague openly wondered, is ? Is our path of destruction inevitable, as we plunder one energy resource after another to exhaustion? Will depleting Earth's hydrocarbons be the latest, greatest, and perhaps final instance?

Until fossils were recognized for what they were, the (c. 541 to 485 mya) was considered to have produced the earliest known fossils, and that situation vexed scientists from Darwin onward. If animals just came into existence from nothing, the Creationist arguments of Darwin’s time may have had some validity. Darwin attributed the lack of Precambrian fossils to the geological record’s imperfection. As this essay’s previous sections have shown, scientists have filled many gaps and Darwin’s theory has held up well.

The closer the timeline of life on Earth gets to the appearance of humanity, the less our ancestry is doubted among scientists, and there is virtual certainty that is humanity’s direct ancestor. Their brains were nearly the size of modern humans and they inherited from their ancestors and used them for hundreds of thousands of years. There is plenty of evidence that migrated to Western Eurasia about 800 kya. But there is evidence that somewhere around 500 kya that began to change; there is evidence of in today’s South Africa. in today’s Germany, along with butchered horses, dated to about 400 kya. Scientists today are confident that was also the direct ancestor of , and the split began around 500 kya. The range of was Africa, West Asia, and Europe, but the advancing and retreating ice sheets of Eurasia, Europe in particular, kept driving southward, and during one of the retreats, it seems that the ancestors of Neanderthals stayed. Neanderthals became a cold-adapted species that specialized in hunting big game. As the evidence demonstrates today, life was a brutal proposition in humanity’s early days, and was particularly harsh for Neanderthals. They probably could not throw very well and relied on ambush predation. Scientists have studied Neanderthal bones and , but a , partly in light of recent evidence that Neanderthals may have also developed wooden throwing spears. But whether Neanderthals had to stab their prey in close quarters or eventually learned to throw weapons at them, the studies of early human bones describe a grim existence. Breaking bones were regular events, particularly skull fractures, and that was for trauma survivors.
