The Frontal Bone as a Proxy for Sex Estimation in Humans: A

Fornication is generally consensual sexual intercourse between two people not married to each other. For many people, the term carries an overtone of moral or religious disapproval, but the significance of sexual acts to which the term is applied varies between religions, societies and cultures. The definition is often disputed. In modern usage, the term is often replaced with a more judgment-neutral term like extramarital sex.
