Brains

Scene: Family driving home in the car Saturday evening; 8-year old Li, in the back seat.

Li, apropos of nothing: “Dad, bottlenose dolphins have larger brains than humans.”

Me: “I’m not surprised; they’re bigger than humans.”

Li: “That doesn’t mean anything. Stegasauruses had brains the size of a walnut.”

Me: “What about elephants? Their brains have to be bigger than ours.”

Li: “Why do you think that?”

Me: “Look at how big their heads are; why else would they need┬áheads that big?”

Li: “To support their ears.”
