Where Did the Expression “I’ll Be a Monkey’s Uncle” Come From and What Does the Phrase Mean?

During the famous Scopes trial in 1925, a Tennessee schoolteacher, John T. Scopes, was accused of breaking that state’s law by teaching Darwin’s theory of evolution rather than the Biblical origins of mankind.

The trial was a sensation and astonished many who had never heard that humans might be related to the apes.

And it is from the trial that came the expression, “Well, I’ll be a monkeys uncle.”
