So why don’t the one species die out? When do they reproduce?
- reubenmorais 3y agoOne /member/ forgoes reproduction, not one /species/. It's akin to a sibling deciding that they won't have kids so they can help their sibling raise their own. The sacrificing family member passes their DNA on because they share DNA with kin.

- wiml 3y agoIt's not that different from a multicellular organism. The vast majority of cells in your body are dead-end lineages. They've specialized into sterile forms so that a few cells in your gonads actually do have a chance to reproduce. Evolutionarily it works because all the cells have the same (or very similar, in the case of kin selection) genes.
