selfish genes

The concept of selfish genes suggests that genes are inherently designed to survive and replicate, acting in their own interest. Rather than focusing on the health or survival of the whole organism, genes influence behaviors and traits that maximize their chances of being copied into future generations. This explains how animals, including humans, may act in ways that benefit their genes, sometimes at a personal or collective cost. In essence, genes are "selfish" in the sense that their main goal is to ensure their own continuation across generations, shaping evolution through their influence on organisms.
