Have you heard of the phrase nature vs nurture? Simply, it asks what influences our behavior? This has been a debated topic since early man. Nature is usually defined as what is given to us before we are born, specifically, as discussed in this text, genetics. Nurture means learning that we acquire from our environment-parents, friends, and other influences.

In this book, we will look at the newest scientific work, how both genetics and environment effect how we behave. Science, specifically genetics, is now finding its way into all areas of everyday life, criminal law, politics, and how our brain is involved in our actions.
