Why is there such a controversy as to how science education policy should require students to learn about evolution? For one, biological evolution, the theory that all living things are modified.
Darwin’s Theory of Evolution is the widely held notion that all life is related and has descended from a common ancestor: the birds and the bananas, the fishes and the flowers — all related. Darwin’s general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) "descent with modification".
