Charles Darwin fathered not just a scientific theory, but a toxic social ideology that fueled racist colonial policies in Africa. In this sobering book, African scholar Olufemi Oluniyi traces the insidious impact of Darwinian ideas on British imperial policies in Northern Nigeria. Drawing on official documents, public statements, and well-attested historical events, Oluniyi documents how concepts such as evolutionary racism and survival of the fittest were systematically used to demean black Africans, consigning some people to a status of permanent inferiority. Rejecting Social Darwinism, Oluniyi makes a compelling argument for the equality of all human beings, and for recognizing Africa's many seminal contributions to the history of human civilization.
