So, with that little bit of technology, humans went from a small band of 10,000 or so -- the same number as Neanderthals everywhere -- and we suddenly exploded. With the invention of language around 50,000 years ago, the number of humans exploded, and very quickly became the dominant species on the planet.
所以，应用很少的技术， 人类就从大约1万少数人发展起来， 同等于那时遍布各地的尼安特人的数量， 我们发明了语言，突然人口爆炸了， 大约5万年前， 人口数量呈爆炸式发展， 非常快地就变成了这地球上的主宰者。
