I want to know the answer to the following question:
Why can one find thousands of anthropological references to the topics?
All the background I'm provided with is that "Topics like racism, slavery, and human sacrifice attract anthropological attention and theories ranging from nutritional deficiencies to genes to acculturation have been proposed, not to mention theories of colonialism and many others as root causes of Man's inhumanity to man.". Is that enough to answer the question?
