Our species, Homo sapiens, evolved in Africa, and humanity's highest levels of genetic diversity are maintained there today. Underlying genetic diversity combined with the great range of solar regimes and climatic conditions found in Africa has contributed to a wide range of human integumentary phenotypes within the continent. Millions of Africans have moved, voluntarily and involuntarily, to other continents in the past 2000 years, and the range of integumentary phenotypes among admixed African diaspora populations is enormous. In this contribution, we do not catalog this variation, but provide basic evolutionary background as to how it developed in the first place.
我们的物种智人在非洲进化，人类的最高遗传多样性至今仍在那里维持着。遗传多样性的基础，加上非洲发现的广泛的太阳辐射和气候条件，促成了非洲大陆内部广泛的人类皮肤表型。在过去的 2000 年里，数以百万计的非洲人自愿或非自愿地迁移到其他大陆，混合后的非洲散居人群的皮肤表型范围非常广泛。在这篇文章中，我们没有列出这种变化，而是提供了关于它最初是如何发展的基本进化背景。
