LOL 民科扯淡哪！要是遗传到双方的糟糕基因就要更恐怖了。有白人容易过敏发胖皮肤
癌多毛的基因，有的黄种人的弱点基因什么得肝炎什么的都到那后代身上就搞笑了。
人家培养生物杂交品种是要淘汰毁灭一大批不成功的杂种，留下个别碰巧集合了优秀基
因的下来，然后再和同样优胜劣汰的个体混合，再淘汰再培育很多代才能得到稳定的成
功品种。
人类生孩子能生10个8个然后掐死绝大部分不成功的失败杂种，留下一个成功的优秀杂
种再去找另一个优秀杂种去混合吗？生孩子是赌场roll dice赌博吗？
而本族的血统通过千万年的大区域的地理范围内部混血后自然淘汰已经比较稳定了，所
以本族内部生出来的孩子自然稳定性要好很多，失败的孩子几率要小不少
现在几大人种都是经过了几万年的进化混合出来的稳定品种，但是这几大人种再混合
就有如你拿斑点狗和藏獒去混合，你希望随便生一个出来的就能比斑点狗或者藏獒更
完美？99%的结果就是一条没价值的土狗。
这句话是网上的，"加拿大著名人种智能方面的权威P.RUSHTON教授经过对不同人种间混
血儿多年的智商研究发现，混血儿的智力通常会比智商占优势的纯正人种低下很多，东
亚人种平均智商高达105，而混血儿（白混黑，黄混白，黄混黑，黄混白）平均智商也
就也在90左右，那么按照RUSHTON教授的说法，东亚人的“混血儿”岂不是越混越“笨
”？"

Race and intelligence

Rushton was a proponent of that idea that racial differences in IQ are
partially related to genetic inheritance. Research areas includes brain size
, effects of inbreeding depression on IQ, and effects of admixture.[28][29]
Application of r/K selection theory to race
Rushton's book Race, Evolution, and Behavior (1995) uses r/K selection
theory to explain how East Asians consistently average high, blacks low, and
whites in the middle on an evolutionary scale of characteristics indicative
of nurturing behavior. He first published this theory in 1984. Rushton
argues that East Asians and their descendants average a larger brain size,
greater intelligence, more sexual restraint, slower rates of maturation, and
greater law abidingness and social organization than do Europeans and their
descendants, who average higher scores on these dimensions than Africans
and their descendants. He theorizes that r/K selection theory explains these
differences. Rushton's application of r/K selection theory to explain
differences among racial groups has been widely criticised. One of his many
critics is the evolutionary biologist Joseph L. Graves, who has done
extensive testing of the r/K selection theory with species of drosophila
flies. Graves argues that not only is r/K selection theory considered to be
virtually useless when applied to human life history evolution, but Rushton
does not apply the theory correctly, and displays a lack of understanding of
evolutionary theory in general.[30] Graves also says that Rushton
misrepresented the sources for the biological data he gathered in support of
his hypothesis, and that much of his social science data was collected by
dubious means. Other scholars have argued against Rushton's hypothesis on
the basis that the concept of race is not supported by genetic evidence
about the diversity of human populations, and that his research was based on
folk taxonomies.[31] A number of later studies by Rushton and other
researchers have argued that there are empirical support for the theory.[32]
