"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.
....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 faster than others, but there is no species alive today that has not undergone changes throughout its existence."
Our second possible fate is extinction. Though the chances of this may seem remote to our brains biased to optimism, the odds are far higher than any of us would like to admit.
"There are an uncomfortably high number of plausible ways this could happen," Solomon wrote.
The third possible fate for humanity, which Solomon explored in depth in Becoming Martian, is that at least part of humanity will evolve into a different species. A decade ago, Solomon deemed this path improbable. Humans today are so interconnected that no population could be siloed enough to speciate.
But now, he thinks the chances have risen considerably. Why?Because the world's richest men are plowing their hefty fortunes into making humans interplanetary. What once seemed science fiction is growing closer to reality with the launch of every large rocket. If a group of humans could colonize another world – Mars, for example – and cease to breed with Earthlings altogether, it may take only ten generations before they grow genetically distinct enough to no longer be considered humans, but rather Martians.
"If we do manage to spread out and survive on planets scattered across our solar system and others, we should expect to evolve, adapt, and speciate everywhere we go," Solomon wrote.
Like the cornucopia of different creatures inhabiting Charles Darwin's beloved Galapagos Islands, humans dwelling on different bodies within the solar system could similarly evolve "endless forms most beautiful and most wonderful." ZeroHedge
RESPONSE: The 4th, most obvious answer that Mr. Solomon misses: That what we see around us is the opposite of "evolution"....For we know that the whole creation groaneth and travaileth in pain... Romans 8:22
