What Darwin Never Knew. Why were humans shocked by the total number of human genes(based on the human genome project) ? What is a “genetic switch” in DNA? How is it important to evolution of new species? Give an example of how a genetic switch alters the physical appearance of an organism. What makes all the difference in the shape of the finch beaks?
