Who wrote “On the Origin of Species”?

B.F. Skinner
Sigmund Freud
Jean Piaget
Charles Darwin

The correct answer is: Charles Darwin

"On the Origin of Species" is a highly influential book that was written by Charles Darwin in 1859. While B.F. Skinner, Sigmund Freud, and Jean Piaget are all well-known figures in psychology and philosophy, they are not the author of this particular work. B.F. Skinner is known for his behaviorist theories, Sigmund Freud for his psychoanalytic theories, and Jean Piaget for his theory of cognitive development. Charles Darwin is best known for his theory of evolution and natural selection, which he presented in "On the Origin of Species." Therefore, the correct answer is D, Charles Darwin.
