Mom Genes Inside the New Science of Our Ancient Maternal Instinct

"Everyone knows how babies are made, but scientists are only just beginning to understand the making of a mother. Mom Genes reveals the hard science behind our tenderest maternal impulses, tackling questions such as whether a new mom's brain ever really bounces back, why mothers are destined to mimic their own moms (or not), and how maternal aggression makes females the world's most formidable creatures."--Publisher's description.
