Race has always had a huge impact on history, society, and culture. But according to many scientists, the concept of race has no biological basis; it is merely a social construct. The American Anthropological Association has stated that race simply cannot be tested or proven scientifically. Because humans have been around for a relatively short time by evolutionary standards, scientists say that there is not enough genetic diversity in humans to allow us to be divided into neat, racial cubbyholes or subspecies. It is generally believed that humans originated in Africa about two hundred thousand years ago and migrated to other continents one hundred thousand years later. Although environmental variations have produced the physical differences in hair and skin we see today, underneath the surface there has been little change.
種族問(wèn)題一直對(duì)歷史、社會(huì)和文化有巨大影響。但是根據(jù)許多科學(xué)家的觀點(diǎn)，種族概念沒(méi)有生物學(xué)上的立論根據(jù)，純粹僅是社會(huì)建構(gòu)出來(lái)的產(chǎn)物。美國(guó)人類學(xué)協(xié)會(huì)指出，種族基本上無(wú)法用科學(xué)方法加以測(cè)試及驗(yàn)證。因?yàn)榫瓦M(jìn)化的標(biāo)準(zhǔn)來(lái)說(shuō)，人類的存在相對(duì)較短，因此科學(xué)家認(rèn)為，人類的基因不夠的多樣化，還不足以劃為純粹的種族分支或亞種。一般認(rèn)為，人類在二十萬(wàn)年前源于非洲，十萬(wàn)年后陸續(xù)遷徙到其它大陸。雖然各地的環(huán)境差異使人們?cè)谕庥^如膚色、發(fā)色上大相逕庭，但是骨子里不同之處極少。
