1. Throughout this course you have read about how racial and ethnic stereotypes have informed immigration laws and policies. How did ideas about scientific racism that developed in the late nineteenth and early twentieth centuries—for example, Social Darwinism, Eugenics, Phrenology, and publication of Madison Grant's Passing of the Great Race—amplify nativism and lead to the passage of new immigration laws and policies? Describe at least three different immigration laws or policies where scientific racism had an effect on their construction and implementation.
