Please explain what moral code is if it is not a direct descendant of religion?
All laws and morals are because of religion.

From an evolutionary prospective:
Man has no interest in preserving other men unless they can be used to insure his existence.
This is why 95% of all male mammals live outside their packs.

A moral code may be descended from religious moral codes, but that does not mean an atheist subscribes to that religion.

There are many aspects of the Christian moral code, for example, that are universal. No murder, no stealing etc. Some aspects of the Christian moral code are not universal and are purely religious in nature (no golden idols etc.)

Man has no interest in preserving other men unless they can be used to insure his existence.

Of course, but a smart man, whether religious or atheist, realizes that it is in his best interests to exist as part of a greater group.
