TRANSCRIPT
Darwin and Freud walk into a bar. Two alcoholic mice—a mother and her son—sit on two bar stools, lapping gin from two thimbles.
The mother mouse looks up and says, “Hey, geniuses, tell me how my son got into this sorry state.”
“Bad inheritance,” says Darwin.
“Bad mothering,” says Freud.

• Gene = a section of DNA that determines or influences the phenotype

MUTATIONS“The capacity to blunder slightly is the real marvel of DNA. Without this special attribute, we would still be anaerobic bacteria and there would be no music.”
Lewis Thomas
