Favours the reproductive success of an organism’s relatives, even at a cost to the organism’s own survival and reproduction.
In the 3rd world chid seem to be their parents slaves and retirment plans. Wonder why Asians do better in school? Their parents push them to because they need their child to take care of them. The child both from inbreding / familly brain washing / cultural infulence. They also see their action and success contributing not just to them but to their entire family or tribe.
Would you die for?
Twenty tribe members
It’s a “fair deal” in evolutionary terms, as siblings are on average 50% identical by descent, nephews 25%, and cousins 12.5%.
The answer to this question determins how inbred you are. I’m fairly sure most people will die for their children but then again I’m an outbred. It’s not even about the child really it’s about saving your genes.
The other sign of how inbred you are is if you are always in a group that is not your direct family. Children do this for safety adults because something is wrong.
Large family gatherings are also typical of the inbred. Outbred people move away from family maybe only visit on holidays when there is nothing else to do. In the 3rd world it’s very typical for that family to live in the same house which of course creates more inbreeding.
A perfect example of Kin selection / Kin Altruism is insects. That’s right bugs the only thing that functions only for the group.
kin discrimination – Less relation more dislike.
“coefficient of relatedness” and “proportion of shared genes,” mean that “animals tend to be altruistic toward those with whom they share a lot of genes.” This is where you end up with mix / cross inbreeding.
Insofar that human kinship patterns are not necessarily built upon blood-ties.
Genetically related individuals will inevitably recognise and engage in positive social behaviours with genetic relatives: rather, indirect context-based mechanisms may have evolved, which in historical environments have met the inclusive fitness criterion
Consideration of the demographics of the typical evolutionary environment of any species is crucial to understanding the evolution of social behaviours.
Altruistic or selfish acts are only possible when a suitable social object is available. In this sense behaviours are conditional from the start.
Under this perspective, and noting the necessity of a reliable context of interaction being available, the data on how altruism is mediated in social mammals is readily made sense of. In social mammals, primates and humans, altruistic acts that meet the kin selection criterion are typically mediated by circumstantial cues such as shared developmental environment, familiarity and social bonding.
