Dr. Dick Frans Swaab is a Dutch neurobiologist and professor at the University of Amsterdam, well-known for his work in the field of brain anatomy and physiology.
His latest book, We Are Our Brains, argues that smoking or drinking during pregnancy can affect your child's sexual orientation.
A description of the book reads:
Moving beyond pure biological understanding, Swaab presents a controversial and multilayered ethical argument surrounding the brain. Far from possessing true free will, Swaab argues, we have very little control over our everyday decisions, or who we will become, because our brains predetermine everything about us, long before we are born, from our moral character to our religious leanings to whom we fall in love with.
