How long have humans used contraception and abortion? Is it fair to say
since humans have had sex other than for procreation? Presumably, said
practices have been around before writing was invented but records can
only go as far back as the written word. The earliest references are in
the Book of Genesis and in Ancient Egyptian records (papyrus paper.)
Contraception and abortion must go back before that...but how far? Other
mammals rely on "natural" forms of birth control but do any use
contraception or abortion?

What is some good reading material?

Also, is the U.S. Bureau of Justice the best place for stats on violent
crime? 

This stuff is for,you guessed it, an article on biological explanations
of violence (i.e. violence as a male reproductive strategy.)
