Human Evolution: ‘Our Ultimate Fate Comes Down To… Three Possibilities’
Human Evolution: ‘Our Ultimate Fate Comes Down To… Three Possibilities’ Authored by Ross Pomeroy via RealClearScience, Everything around us seems to be changing at breakneck speed. Twenty years ago, smartphones were niche products. Twenty years before that, computers were clunky behemoths. Forty years before that, far more Americans traveled by train than by plane. Forty years before that, cars were just starting to supplant horses. Over the past couple millennia, a mere blip of Earth’s history, humans have manifestly reshaped the planet – from the physical to the biological. The ground, the oceans, the air, the flora, the fauna – nothing is as it was. And yet, despite this radical transformation, it can seem like we ourselves haven’t changed much at all… But that’s an illusion. “Humans are still evolving,” Dr. Scott Solomon, an Associate Teaching Professor at Rice University specializing in ecology, evolutionary biology, and scientific communication, wrote in his forthcoming book Becoming Martian: How Living in Space Will Change Our Bodies and Minds. Sure, over the last 10,000 or so years, our physical alterations have been relatively muted compared to the changes seen in society and on our planet. Essentially, we’ve shrunk a bit, and our jaws have weakened. But even a little change is still change, and it begs a question: “In the far-flung future, what will happen to us, evolutionarily speaking?” It’s a question that Solomon considered in his 2016 book, Future Humans: Inside the Science of Our Continuing Evolution. He surmised that our ultimate evolutionary fate could follow one of three basic trajectories. The first is a standstill – our species will remain roughly as it currently is. But Solomon thinks this is unlikely. “So far, in the 3.7-billion-year history of life on Earth this has not happened to a single species… All species change, some
