有次翻到wiki看到尼安德塔人(Neanderthals)
Genetic evidence published in 2014 suggests that Neanderthals contributed to
the DNA of anatomically modern humans, probably through interbreeding between
50,000 to 60,000[17] years ago with a population of anatomically modern
humans.
在2014年发表的基因证据显示，尼安德塔人贡献其DNA于现代解颇学的人类内，可能
是在五到六万年前，与现代解颇学中的人类的杂交所致。
...by the time that population began dispersing across Eurasia, Neanderthal
genes constituted as much as 1–4% of its genome.
当演化开始分歧， 尼安德塔人贡献了大约1~4% 的基因组于现代人。
There may be even more Neanderthal genes in non-African humans than
previously expected: approximately 20% of the Neanderthal gene pool
was present in a broad sampling of non-African individuals, though each
individual's genome was on average only 2% Neanderthal.
可能还有更多尼安德塔基因在非非洲人身上：大约20%的尼安德塔基因库
存在于广泛的非非洲人取样上。然而，平均每个人的基因组大约有2%的尼安德塔基因。
