If you don't understand this, you don't understand evolution
The smell of poop is bad for humans because it contains harmful bacteria, and our ancestors who avoided it were more likely to survive and pass on their genes. This idea links to the concept of natural selection, which is not just about individual survival or species survival, but about the survival of genes. Genes are units of DNA that can replicate, mutate, and influence traits, making them the fundamental drivers of evolution. Even altruistic behaviors, like an animal warning others of danger, can be explained by genes helping copies of themselves in relatives. Although this 'selfish gene' theory has criticisms, like not accounting for genetic drift or the complexity of gene interactions, it offers a powerful way to understand why living things behave the way they do.
