""Rape was legislated as a crime in ancient societies too. Both rape and sanctions against rape are human universals"".

I question whether rape was broadly legislated in "ancient times", or a "human universal" (verses a social norm). This may need a bit more context and definition for consideration of "rape" and "legislation" (a crime), or "social taboos".

Many "more recent" human soceties legislated against rape. However, I suspect the definition of rape and when and where it was (is) not a crime differs. For example, it seemed acceptable in some societies as long it does not involve members of that society. Additionally, laws against rape within a union (marriage) seems silent in some societies.

I recall reading that in many ancient societies, the taking slaves from the opposing side and rape during or following conflict seemed quite common.
