生的孩子不会有问题吗
对达尔文的婚姻很感兴趣。用中国古人的说法就是“不殖,不蕃”。。。

Charles Darwin's studies of heredity, adaptation and evolution included many experiments into the effects of crossbreeding and inbreeding in both plants and animals. Such consanguineous pairing often resulted in weaker, more sickly descendants.
Ironically, his own lineage and marriage could have been experiments as well. At the age of 29, he proposed to his first cousin, Emma Wedgwood, the daughter of his mother's brother. Darwin realized the dangers of inbreeding and wondered if his close genetic relation to his wife had had an ill impact on his children's health, three (of 10) of whom died before the age of 11. In a letter to friend, Darwin noted his concern for his children, writing that "they are not very robust."
Darwin's marriage to his cousin was not the only mixing of blood in the two lines. The Darwin-Wedgwood family in fact had several instances of close family matches, and a new analysis, published online May 3 in the journal BioScience, shows that some of Darwin's concerns about his offspring's health might have been valid.
The analysis, led by Tim Berra, professor emeritus in the Department of Evolution, Ecology and Organismal Biology at the Ohio State University in Mansfield, found that Darwin's kids did have "a moderate level of inbreeding" and in the family's children, there was "a significant positive association between child mortality and inbreeding." |
