Something I think about a lot, especially when thinking of the great diversity of human experiences, is how incredible human adaptability is. Humans have found ways to survive across the globe. Humans appear to have first evolved in Africa, with several different waves of human species spreading from Africa across Europe and Asia, and eventually across the oceans to the Americas and to Australia. From savannas and plains, to tropical jungle islands, to frozen tundras, humans have found ways to adapt and live. At this point, we have found ways to survive for long stretches submerged in metal tubes or floating outside the atmosphere in tubes. We have settled in the driest deserts, the wettest rain forests, and even have ways of surviving in the coldest, frozen polar ice-scapes.
This adaptability of humans is truly astonishing, especially when you look back at human history and put us in context with other animals and species. Yuval Noah Harari does this in his book Sapiens and he marvels at how quickly the human species was able to conquer the globe. He writes, “The human blitzkrieg across America testifies to the incomparable ingenuity and the unsurpassed adaptability of Homo sapiens. No other animal had ever moved into such a huge variety of radically different habitats so quickly, everywhere using virtually the same genes.” Adaptability has been a human super power since the early days of the cognitive revolution, when humans began to find ways to live in places that our genes had not evolved to fit.
I’m in awe of our adaptability and think about it whenever I am in a situation I didn’t expect and when I meet people who live dramatically different lives than my own. I am inspired by what some people can push their minds, bodies, and existence to become. I am also dismayed at how terrible life can be for others, and how they nonetheless manage to survive. From the Holocaust, to modern civil wars, to the squalor of tribes in the poorest parts of the globe, it is simultaneously inspiring that humans have survived such awful conditions and depressing. Our adaptability means we can survive and put up with terrible things, languishing in a state of mere existence for years or even generations. Just as our adaptability can allow us to be astronauts, athletes, and chess grand masters, our adaptability can allow us to be prisoners of war, sex trafficking victims, and impoverished peoples. Our unsurpassed adaptability is what allowed our species to conquer the planet, but it is also what has allowed us to pump green house gasses into the atmosphere and allowed us to devastate wildlife and ecosystems.
Our adaptability is amazing and has been since the early days of Homo sapiens, but it does have a cost. While it can allow us to be our best, it can perpetuate our survival at our worst. It has allowed us to flourish as a species across the globe, but has also allowed us to do great harm to the planet. Moving forward we need to continue to adapt, but should strive to do so in a way that makes life better for all, that finds a new Pareto efficiency between all of us and our planet.
