| Yes Packratt is right, groups or families with genes that give them better instincts of group preservation and co-operation will florish over groups with no such instincts.
Therefore it only makes sense that the groups and families on earth today that have survived all this time will be the ones with very tuned instincts for social co-operation and group preservation, which is what we see
These instincts aren't designed to protect the whole species, only your group. By promoting the lives of those more closely related to you, you are protecting your families gene pool. In effect your own genes are using you to keep them going by feeding you instincts to want to do so |
