[Serious] Literal and Not Literal

[Mister Agenda]

The genes you and your sister have in common (and most of the ones you don't ) are copies of your parent's genes. There are no extant 'original genes' to survive. It's all copying and copy errors. Genes don't care about anything, but it's a brute fact that if your sister survives to have children, some copies of your genes will be passed on, even if you die before reproducing. If instinctive family bonding influenced by a complex of genes increases the odds of more copies of those genes being passed on, the predisposition to bond with close family members will be passed on. The same is true if bonding in bands or larger groups conveys similar benefits. It's information, and it's math, but it has a concrete expression in phenotypes.
