Among the things I think about sometimes is how we got here as a species, and where we’re going.
We tend to think of ourselves as a young species, having only discovered writing (and with it, history itself) in the past 5,000 years, and civilisation (with its permanent monuments) 5,000 years before that. Earlier than this, our history as a race of humans goes quite dark. Archaeology tells us a few things, but the further back we go, all we have are fragments from our past. We can quite easily forget that we are a very old creature indeed. How long ago was it since we discovered language, since we started singing, since we started praying, since we discovered a sense of humour? It’s hard to say, yet it’s quite probable that such traits predate homo sapiens, going back through multiple ancestral species. Were we to travel back a couple of million years, maybe we would still see ourselves in our austrolopithical forebears.
I remember reading a book some time ago, that one group of our ancestors (or possibly close cousins) spent over a million years fashioning an early stone tool with practically no development in all that time. That’s tens of thousands of generations just hammering away with little sense of innovation. They were rooted in the animal world – lives full of fury, struggle and passion, but not one given to legacy or creative accomplishment. Maybe there were stirrings there. Maybe, every so often, one of them came up with an idea, but they were quickly hit over the head, or eaten by a lioness, before that idea (or their genes) had a chance to spread.
I ask myself if that’s where we’re ultimately going back to. If anything has been successful in the long term on this planet, it’s been that patient toiling away with little progress through the generations. Among all the animals, a sense of constructive wonder seems to be selected against. In the single case where it has succeeded, it’s lead to an exponential increase in technological development, resulting in a potentially untenable situation full of nuclear weapons, over-population, resource depletion, multi-species extinction and the prospect of disastrous climate change. Maybe our ultimate fate (if we survive this time at all) is a return back to the animal realm. Maybe, 90,000 generations hence, our distant children will be back in the trees, or scurrying around in holes, or hammering again on rocks with little thought for art and music.
I think about the last person in that line, looking around at her species and wondering about it all, before death finally takes her away and the universe once again becomes dim and distant to humanity.
