Some scientists have argued that civilisation’s rise ended natural selection. It’s true that selective pressures that dominated in the past – predators, famine, plague, warfare– have mostly disappeared. Starvation and famine were largely ended by high-yield crops, fertilisers and family planning. Violence and war are less common than ever, despite ...
Humans will almost certainly evolve to live longer – much longer. Life cycles evolve in response to mortality rates, how likely predators and other threats are to kill you. When mortality rates are high, animals must reproduce young, or might not reproduce at all. There’s also no advantage to evolving mutations that prevent ageing or cancer - you w...
Animals often evolve larger size over time; it’s a trend seen in tyrannosaurs, whales, horsesand primates - including hominins. Early hominins like Australopithecus afarensis and Homo habilis were small, four to five feet (120cm-150cm) tall. Later hominins - Homo erectus, Neanderthals, Homo sapiens - grew taller. We’ve continued to gain height in h...
After people left Africa 100,000 years ago, humanity’s far-flung tribes became isolated by deserts, oceans, mountains, glaciers and sheer distance. In various parts of the world, different selective pressures – different climates, lifestyles and beauty standards – caused our appearance to evolve in different ways. Tribes evolved distinctive skin co...
Last, our brains and minds, our most distinctively human feature, will evolve, perhaps dramatically. Over the past 6 million years, hominin brain size roughly tripled, suggesting selection for big brains driven by tool use, complex societies and language. It might seem inevitable that this trend will continue, but it probably won’t. Instead, our br...
There were once nine human species, now it’s just us. But could new human species evolve? For that to happen, we’d need isolated populations subject to distinct selective pressures. Distance no longer isolates us, but reproductive isolation could theoretically be achieved by selective mating. If people were culturally segregated – marrying based on...
So far, I’ve mostly taken a historical perspective, looking back. But in some ways, the future might be radically unlike the past. Evolution itself has evolved. One of the more extreme possibilities is directed evolution, where we actively control our species’ evolution. We already breed ourselves when we choose partners with appearances and person...
How will natural and cultural selection shape our appearance, personality and intelligence in the next millennium? This article explores the past and present trends and predicts the possible futures of human evolution.
To understand our future evolution we need to look to our past. Will our descendants be cyborgs with hi-tech machine implants, regrowable limbs and cameras for eyes like something out of a science fiction novel?
Hear his plan for putting the planet back on the path of sustainability over the next 10 years -- and protecting the future of our children.
