FRANCIS: This book about evolution is fascinating! 
CHAD: What is evolution?
FRANCIS: It's the way species change in response to their environment! All species are evolving all the time!
CHAD: Even us?
FRANCIS: Sure! Let's say that tomorrow there's another ice age! People would probably become hairier to protect themselves from the cold!
CHAD: Ha! That's funny!
NATE: So...we'd all just start growing more hair?
FRANCIS: No, no...It would happen gradually! It would take thousands of years!
NATE: Tough luck, Dad!

DAD: Thanks so much.
