The gene ASPM (abnormal spindle-like microcephaly associated) is a speci
fic regulator of brain size, and its evolution in the lineage leading to
Homo sapiens was driven by strong positive selection. Here, we show tha
t one genetic variant of ASPM in humans arose merely about 5800 years ag

发帖数: 2165 | 2 大约6000年前出现的ASPM基因，伴随着文字和农业的诞生
欧洲人和中东人此基因频率较高，东亚人较低，非洲人最低
A new allele (version) of ASPM appeared sometime between 14,100 and 500
years ago with a mean estimate of 5,800 years ago. The new allele has a
frequency of about 50% in populations of the Middle East and Europe, it is
less frequent in East Asia, and has low frequencies among Sub-Saharan
African populations.[6] It is also found with an unusually high percentage
among the people of Papua New Guinea, with a 59.4% occurrence.[7]

difference in average IQ, providing no evidence to support the notion that
the gene increases intelligence.
"the gene"，不是"all genes"
原文的意思是这个new ASPM allele基因对智商没影响，不是所有基因都没影响。智商
不是基因决定的难道是吃出来的？ |

发帖数: 558 | 4 I guess you were referring to this:
The mean estimated age of the ASPM allele of 5,800 years ago, roughly
correlates with the development of written language, spread of agriculture
and development of cities.
Subject: "The mean estimated age"
Distilled sentence: The mean estimated age correlates with development of
written language...
It's not saying that the gene itself have anything to do with these events.
It's just that the mutation happened around that time.
That means almost nothing. |

这里当然说的是这个ASPM的新的基因型
它本身跟智商测试分数没有相关性，但是跟其他的事件（农业和文字有相关性） |

这个是你要的DAB1基因答案
Gene variants & associated phenotypes in humans
In a study by Dr. Scott Williamson of Cornell University, A newer version of
the DAB1 gene had been shown to be universal among those of Chinese
ancestry, but not found among other global populations.[7][8] Being related
to organizing the cells of the areas in the brain associated with cognitive
function, it is speculated that the DAB1 mutation in the Chinese may be a
parallel genetic evolutionary route to possibly accomplish an equ... 阅读全帖 |

你的有我无我 一 看完了， 二在那里？
至于背后的东西， 是很多的， 还有人从基因角度来说， ASPM gene 是制造闹神经的
蛋白
重要基础，SOD1 gene 是战斗清洁作用的， 这都还是gene表层的， 说到 epigenetics
那又是更多了。
所以， 没人能通读和了解所有这背后的深层次的东西
