Eternal Youth from Young Blood?

Demographics shifts wealth and power to the old. Youth gets student debt, unpaid internships, crazy property prices and now the prospect of getting the life squeezed out of them – drop by drop – to keep a population of ageing vampires young.

I can’t see this ending well.

Stone Tools Before Homo

The production of the earliest stone tools has now been bushed back to 2.6 million years ago, before the homo genus even evolved, and half way back to our split from chimpanzees! (although this split is a very vague date). Chimps have also recently been shown to use spears to hunt other mammals.

The vast amount of time between then, and 50K BCE when we started doing all the other interesting human things we are so proud of, is staggering – what were we doing for two and a half million years?! Probably chilling.
