The article discusses human genome research that shows that humans continue to evolve, and more quickly in the last 10,000 years than at any other time. These findings contradict pronouncements made by evolutionary biologists and psychologists that changes in human biology and brains had slowed or ...
于是乎,任何基因都可以继续存在,任何突变的结果都可能被继承(不考虑不孕不育嫁不出去等案例)。也就是说:人类仍在“演化”。那么“进化”呢?在技术还未触及的地方,仍然存在,比如尼泊尔夏尔巴人。至少我们现在还不能往所有雪域高原去注射氧气。肆意砍伐森林、燃烧化石能源,地球的肺受损,接着我们几代人的肺部受损,说...
After my pubic lectures on evolution, someone in the audience asks, "Are we still evolving?" People want to know if humans are getting taller, smarter, better looking or more athletic. My answer is truthful but disappointing: We're almost certainly evolving, but we don' t know in what di...
Are we still evolving? If so, have our culture and our technology changed our evolutionary trajectory? Using new genetic inventories of world populations, researchers are now tracing our recent evolutionary path in remarkable detail. They are discovering that our culture and our general restlessness ...
But not only are we still evolving, we’re doing so even faster than before. In the last 10,000 years, the pace of our evolution has sped up, creating more mutations in our genes, and further natural selection from those mutations. Here are some clues that show humans are continuing to...
Like other species, we are the products of millions of years of adaptation. Now we're taking matters into our own hands.
The researchers found brain structures such as white matter, gray matter and hippocampus (a brain region involved in learning and memory) also increased in size when comparing participants born in the 1930s to those born in the 1970s.
But not only are we still evolving, we're doing so even faster than before. In the last 10,000 years, the pace of our evolution has sped up 100 times, creating more mutations in our genes, and more natural selections from those mutations. Here are some clues that show humans are conti...
Are we still Evolving?: Directed by Oliver Bootle. With Alice Roberts, Cynthia Beall, Mark Hodson, Steve Jones. Dr Alice Roberts asks one of the great questions about our species: are we still evolving? There's no doubt that we're a product of millions o
. Not only, they claim, are we evolving faster than ever, but we're doing it to ourselves. Juan Enriquez and Steve Gullans argue that humans have 2 evolution—not just in our own species but virtually in all species: "For better or worse, we are increasingly in charge. We are the...
