Are we undermining our own evolution?
tokenadult: A lot of people talk about dysgenic trends that they imagine must be happening because the weak are being protected from having their genes eliminated from the human gene pool. But few notice that the data show improvements in phenotype that are so large in effect size that they can't even be explained by ENORMOUS favorable changes in gene frequencies.http://books.apa.org/books.cfm?id=431712Ahttp://www.springer.com/statistics/social/book/978-0-387-949...The simple empirical fact is that human ingenuity and shared cultural knowledge is improving the human condition faster than any process of natural selection of genes could, and we can all join in on that, whatever genes we have. And it won't be too long before we can start manipulating the genes of our descendants, if we so choose.
