But your anecdote is exactly what is explained in the article: the new environment (such as contraceptives) which lead to your ancestors having less kids, will cause increased selection on fertility traits in the future. This will reverse the trend of decreased fertility.
Traits that will be selected: a desire to have more kids, physiological changes that cause resistance against contraceptives, tendency to have twins, etc.
- novalis78 7y agoThat makes sense from an evolutionary/ biological perspective- it’s like contraceptives appear to nature like a filter - a global pandemic, an extinction event of sorts. So those who nevertheless have more children - ipso facto- pass down their trait of having larger families despite the availability of a baby pill. Fascinating hypothesis. My next question would be if there is a biological link to religion and fertility.
- tropo 7y agoYes, religiosity is inheritable. It's been proven with twin studies. Therefore, if religious people have more kids, having more kids is inheritable.
