Two million years of climate change made us what we are

Two million years of climate change has made us human — in a ying meets yang contradiction, while climate change destroyed cultures and groups,  without it, we would not be who we are. The brutal forces of Nature tested our ancestors with droughts, storms, floods and tidal surges, but if the climate had stayed the same, would we have had Bach, Leonardo, and Newton?

At the end of the day, we have a civilization that allows millions of people to pursue happiness without fear that they will die of dysentery, be murdered by marauding barbarians, or lose their children to slave traders.

We are the lucky bastards at the end of a long line of poor sods who struggled and suffered to stay one step ahead of the reaper.

Here are two stories of studies that suggest dramatic effects of climate change on long lost peoples. The second, below, may finally explain the disappearance of the mysterious well developed aboriginal artform known as the “Bradshaw” style.

On misanthropology

misanthropology (from Urban Dictionary): the scientific study of the origin, the behavior, and the physical, social, and cultural development of hatred in humans misanthropology-the opposite of optimistology.

Lost word, sighted on the Neologism thread at (Diggingintheclay) that inspired The Doomsians are Panixilated post.

For what it’s worth, I  think misanthropology is often just a veneer, it’s not a real hatred at all, but just the semblance of it. It’s much more small minded. It’s not about “hating humans” so much as it is about impressing the chick (or boy) next door. A kind of competition to get to snob-land first:  ‘I look down on humans more than you do.” (Which translates loosely as: I, the exalted one, speaks from a greater height, fellow misanthropist….)

It’s about status, eh. Like everything.

Rewriting the dawn of civilization

If National Geographic had more stories like this one, I’d be inclined to subscribe. This is fascinating stuff.

Seven thousand years before Stonehenge was Göbekli Tepe in southern Turkey, where you’ll find ring upon ring of T-shaped stone towers arranged  in a circle. Around 11,600 B.C. hundreds of people gathered on this mound, year after year, possibly for centuries.

There are plenty of mysteries on this hill.  Some of the rocks weigh 16 tons, but archaeologists can find no homes, no hearths, no water source, and no sign of a town or village to support the hundreds of workers who built the rings of towers. The people apparently, unthinkably really, were nomadic, as far as we know, they had no wheels, and no beasts of burden. True hunter gatherers, whose first heavy building project was not a home to fend off the elements, but a religious sacred site.

Perhaps we should not be so surprised, after all, we know the pyramids, the largest and oldest surviving buildings didn’t house people or grain either –  the only humans they keep warm were dead ones. In a sense, the theme repeats. It takes extraordinary expertise and effort to move tons of rock, especially [...]
