BBC地平线系列: 我们还进化吗的剧情介绍,
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 of years of evolution. But thanks to modern technology and medicine, did we escape Darwin's law of the survival of the fittest? Alice follows a trail of clues from ancient human bones, to studies of remarkable people living in the most inhospitable parts of the planet, to the frontiers of genetic research to discover if we are still evolving - and where we might be heading.
我们还在进化。一部能引起我深入思考的科普纪录片。高智力必然是进化的方向之一。进化还是变化……。Are we still evolving?。

我们还在进化。虽然科技进步使得发达社会的人们基本都能活到生育年龄,因而抵消了绝大多数的自然选择压力,但是细菌和病毒始终在变异,因此人类大面积死亡的流行疾病爆发的可能性不能排除。目前基因工程也发展到人类可以自主选择后代的遗传性状,恐怕这才是将来人类进化的最大动力。
环境的变化会促使基因变异,催生新物种。进化也许不仅仅和自然选择有关,还可能是被引导的。也不仅仅和生理有关,还可能和智力有关。但没有回答问题,我们会进化到哪一步?人工智能+基因工程+脑机接口都有可能进化成一个新物种。
一篇小作文
最需要普及的科普内容之一
对标题的回答无疑是肯定的,问题在于:人类从古至今改善生存环境、延长寿命的技术(如医学)是否大大减缓了基于自然选择的自身的进化?基因技术的发展能否让未来的人类操纵自身的进化?不管答案如何,结尾的一句话也许值得思考探索这类问题的人们放在心里——“人类是特别的,但也没有那么特别”。
