Natural selection does not disappear with age, according to a new evolutionary demographic model. This conclusion is at odds with the widespread belief that ending reproduction relaxes purifying selection on alleles that increase our ageing body’s vulnerability to diseases such as cancer, Alzheimer’s or diabetes.

自然选择如何塑造我们的晚年

根据一种新的进化人口模型，自然选择不会随着年龄的增长而消失。这一结论与普遍认为结束生殖放松了对等位基因的纯化选择不符，这些等位基因增加了我们衰老的身体对癌症、阿尔茨海默氏症或糖尿病等疾病的脆弱性。
