Question. Why are we (humans) more likely to help people genetically related to us than people who are not?

My understanding of this question as follows:

Because the reproduction of people genetically related to us can help us spread our genes. People genetically related to us are also more likely to help ourselves to reproduce.

Is this correct? What am I missing?

I was wondering if anybody had anything, especially intuition or some finer nuances, to add to what I have to say.

    $\begingroup$ Why was this question closed? The idea that humans tend to be altruistic toward genetically related individuals is not outlandish. $\endgroup$ – canadianer Mar 27 '17 at 7:45
  • $\begingroup$ This question seems to fall under the field of sociobiology, and more specifically I think kin selection. It's a controversial topic. If sociobiology is a subfield of biology then it shouldn't have been closed. On the other hand if sociobiology is more of a social science, then I guess it should be asked somewhere else. Still, it's a very interesting question. $\endgroup$ – Zebrafish Feb 25 '18 at 12:44
  • $\begingroup$ I heard something like this before. E.g. it's important that children look like their parents because if they don't the mother probably cheated on the father. Promiscuous partners increase the chance of catching a disease, and so evolution made monogamous couples more prone to procreating which also helps to root the behaviour. Furthermore humans are social beings and like other primates, we strive together, so our relationships are very important. So much so that we even developed language. $\endgroup$ – Yuri Borges Jan 31 '19 at 17:07
