A "mad" scientist believed that he could create a "slave species" by forming a hybrid between humans and chimpanzees. He collected eggs from female chimps and sperm from human males and then allowed the two kinds of gametes to come together in a test tube. Fortunately, the human sperm were incapable of fertilizing the chimpanzee eggs due to the lack of a proper receptor on the surface of the egg. Which isolating mechanism was working to keep these two species separate?
