Diversity is not a bad thing, because even though we think of humans as very diverse, we came so close to extinction that all of us descend from a single African mother and the consequence of that is there's more genetic diversity in 55 African chimpanzees than there are in seven billion humans.
多样性是好的， 尽管我们认为 人类多样性已经很丰富了， 但是因为我们来自 同一位非洲母亲的基因， 我们也有灭绝的危险。 而且它的后果是， 55只非洲黑猩猩的基因的多样性 都比70亿人类丰富得多。
