Not all of it. Only the basic instinctual behavior. I personally think that too much is loaded on genetical aspects and less considered what the actual changes in your brain happens when you are brought up and interact with society. Genes affect, I agree that, but not nearly all is there. The mere moral differences in cultures supports that. Also, fear of punishment is very big factor. It shackles us to act in a way that society considers morally right.
That might be true, but I'd say that it is more about our own survival than survival of the human race. Take stealing. Taking items that belonged to others has probably always been true. Even earliest hunter gatherers protected their bow and arrows and other tools with great care. But after society began to evolve, people started to form cities, tribes and nations. That could be the turning point when thievery began an actual profession. The punishment was usually brutal, death or torture. Still thieves have basically organized everywhere around the world and it has been shaped into a form of art.
If I understood this right, then I agree quite bit of it. Humans are so complicated with our social frame that you cannot see as from purely biological ( genetical ) perspective. Survival for us is not that much evading poisonous snakes, finding food and water etc. anymore. It is more about surviving the interaction with other people and society and this is why general morality/laws were invented that people could even live together. Especially, when our cities are so big now.
But I haven't seen any explanation that could sway me from my view that morals are pretty much only sideproduct of society. If you isolate a child from society and raise him up ( feral children as example, too bad we cannot.. rather it is not morally acceptable.. to conduct a experiment to see what happens in controlled observation) he will most likely not see why he couldn't smash your tv, eat your food, bite someone who touches him et cetera. He only calculates the risk and reward of an action according to what he knows and has learned, which in his case, is pretty much none.
Sorry, I was a bit rush so lots of stuff probably is missing or written down in confusing way.
