Thus, something that looks like altruism does arise out of what is essentially selfishness. This is what explains the "biological morality" and innate sense of right and wrong. As you would understand, killing your own child makes no sense because it's DNA is so close to your own - it has 50% of your genes. But killing someone elses child might not be a good idea either because it's the child of someone whom you are in a community with and who your fitness is partially dependent on. If it is a child from a community competing for the same resources as yours, then the act may make sense from a biological point of view.

So you have some good points, but don't overlook these essentials.
