Unfortunately once again: this is an an intellectual fallacy, an attempt to use nature and evolution as a way to justify the way one things to be. The idea breaks down as soon as you take the most cursory look at actual evolution. The woman and the alpha – in this view – gets the best of both worlds; the alpha gets to spread his genes while the woman gets not just superior genetic stock for her offspring but also physical and material support as well. Meanwhile the poor cuckolded beta is stuck having his genetic line cut off while expending resources raising another man’s child. Even amongst modern stone-age tribes, such as the ones in the Amazon and South-East Asia, parential lineage isn’t a strict binary; most believe in the concept of multiple fathers contributing to the creation of a child.
