How can we distinguish what is biologically determined from what people merely try to justify through biological myths? A good rule of thumb is ‘Biology enables, Culture forbids.’ Biology is willing to tolerate a very wide spectrum of possibilities. It’s culture that obliges people to realise some possibilities while forbidding others. Biology enables women to have children — some cultures oblige women to realise this possibility. Biology enables men to enjoy sex with one another — some cultures forbid them to realise this possibility.
