Human evolution: looking back, looking forward

I have said this before, but we really are a strange species.

On the one hand, the Aboriginal Australians have stories that go back ten to fifteen thousand years, describing how their formal lands were flooded when the sea level rose after the last ice age. This made me remember an article about disposal of nuclear waste and the super intelligent nuclear physicists thinking about how to label the area so that future generations will know it’s there. The local Native American tribe told these scientists not to worry – they’d tell the future generations. It made me laugh.

But then, on the other, Yuval Noah Harari writes a book:Sapiens: A Brief History of Humankind about how our species of humans becoming so powerful because we can believe stories (including complete bullshit), and thinks that the first really big impact of humans in the world was the arrival of humans in Australia, after which the megafauna of that continent disappeared from the record (a little further back than the sea-level rise in the story). The second big impact he says was when humans arrived in America and destroyed even more species of giant mammals.

In case it’s not clear, the book does not say the rise of humankind was in fact a great thing: for individual humans or for other species. He does speculate about the future, and reckons that humans will quickly evolve into some kind of new human-computer hybrid… But first, there will probably be a speciation event between the poor and the ultra -rich, the latter going on to becoming superhuman and somehow avoiding the coming problems.

One thing he seems to have missed (from the radio show I listened to), is that there are still people who live like our ancestors did, hunting and gathering, and they are, I hope, still as happy as Harari believes (and I agree) our ancestors were. I can only say that the this book is a huge reason to support NGOs like Survival International (to which 10% of the royalties of my second book in the Silver Nights Trilogy will be donated) so these people can be left alone in their happiness, and not made sad just because we are so blind to our own sadness that we think we are helping them. I can only hope that in the future, when the rest of us have evolved into whatever strange stuff will befall us, there will yet be uncontacted tribes living in the forests the way they have since they destroyed the megafauna.
