I find this headline misleading “Culture may trigger evolution of human features, study finds.” Why? Because it implies that culture as a whole- religious practices, laws, artwork, literature, plays a part in human evolution. And that’s not what their study has shown at all.

They are talking about one very specific part of “culture”, the part that deals with marriage and procreation. It seems rather obvious to me that if one mans’ sons (not all his children, just his sons) comprise one quarter of the population, then that man’s genetic traits are going to be passed down to future generations.
