چکیده
Of all the differences that distinguish people, the most obvious and most intriguing one is their sex. The relationship between males and females has had a profound influence on human civilization, causing wars and societal up heavals, and inspiring countless works of art, music and literature. For as long as humans have both struggled with and enjoyed the existence of the two sexes, they have tried to understand how this crucial difference comes about. Philosophers, naturalists and, more recently, scientists have debated this question for more than 3,000 years. Yet, despite the progress made, the debate remains open.
