There is no universal morality. Morals are likely partial genetic and partially cultural. Natural selection selects for cultural values ("morals") that allow a culture to survive to destroy other cultures. Random morals are constantly being created - mutations. They sometimes are negative for cultural survival, sometimes neutral, and sometimes positive. Based on a changing environment morals needed for a culture to survive will also change. Over a long enough time, some moralistic behavior has become embedded in our DNA. (e.g. protecting children). Moralistic behavior that is embedded in DNA is probably the closest thing we have to "universal morality". Controversial examples might be procreating at 13. When people died at a much younger age, it was not immoral to procreate as soon as we were able. Now it is morally abhorrent. Some cultures still allow it. It is absolutely not universally immoral.
