According to the non-Christian, Jewish, Muslim people. Morals just appeared out of no place like life did.
Two people standing in a grove of trees one day just decided that being naked was wrong. Why?
Also how did the decision of two people change the way a bunch of chimps or apes would dress or not dress?
Two people or chimps or apes, made a decision that made everyone else on the planet at the time decide to start wearing cloths all the time instead of when it was cold.
You guys like to have everything just happen no ryme nor reason to it.
I think it would help if you defined, moral. I think you may need to define varying degrees of social norms.

Animals don't have souls or morals.They act purely on instinct and programming,like a computer.Humans have something else,something that let's us distinguish between right and wrong.Animals can't do that.
Thats not true at all. Social animals can be said to have social norms, values, taboos and even morals. Individuals within the society are free to choose to break or follow the rules, just as in human society. I would suggest watching meerkat manor on animal planet to see just how serious and complex animal societies can be.
As to the original question, I would add that early hominids started off in small, yet complex social groups. As we evolved, both physically and in agriculture use, we lived in larger and larger societies. The surplus of food allowed different individuals to spend more time pursing non-sustenance related tasks. This eventually allowed for class differentiation in our societies. Because societal behaviors are learned and not inherited, it required a great deal of cultural teachings for our children.
Complex social life certainly has an evolutionary basis. The "2 heads are better than one" mentality if you will. Living in complex societies provides organisms with a great many benefits, shared parental care, shared food etc. Problems arise in complex groups however, if all individuals are not mutually altruistic (cheaters arise in the group) then the group will eventually fail. To counter cheaters, or selfish individuals, groups develop first simple, then more complex rules. Breaking these rules results in exile from the group. The incentive to follow the rules comes from the benefits provided of group life.
We can look at this with an example of a simple game.
Lets say you and a friend are both picked up by the police for possibly committing a crime, actual guilt is irrelevant in this example. The police separate you two in different cells and you are told the same thing.
If you both confess to the crime you get 5 years in prison.
If neither of confess the police will pin a part of the crime on each person, resulting a 2 year sentence for both of you.
If one of you confess, you can strike a deal with the police and the other will get 10 years in jail, while you go free.
This game is called the Prisoner's Dilemma, it is an example of a zero-sum game in game theory (ever see a beautiful mind?) and is used extensively in economics as well as biology.
Upon first inspection the choice seems clear. You rat, get to walk and your friend goes to jail. For the same reason you rat though, your friend is likely to rat. Now you both get 5 years in prison. The best outcome for the group then becomes for you two to cooperate, by not confessing. You both serve your 2 years then get to go home.
Thus, the group has an unspoken rule, a moral if you will. The altruistic behavior (not confessing) far outweighs the selfish behavior.
In this same way, "morals"/Norms/Taboos arise in complex animal social groups. The benefit of cooperating outweighs the risks associated with selfish behavior.
