which of the following is an example of scientific racism used during the nineteenth and twentieth centuries?

Answer 1

One example of scientific racism used during the nineteenth and twentieth centuries is the concept of social Darwinism. This theory used Charles Darwin's theory of natural selection to argue that certain races or ethnic groups were inherently superior or inferior to others based on their perceived level of advancement or "fitness." This theory was used to justify colonization, imperialism, and racial segregation, among other practices.
