Professor David Coltman labels bighorn sheep as either aggressive or docile based on how they act when they are trapped in a pen. Do the bighorn sheep act mad? Stomp? Try to attack? Then they’d be labeled aggressive. Are they calm and wait to be let out? Let the researcher pet them? Then they’d be labeled as docile.
How would you act trapped in a pen?
Turns out that some bighorn sheep are very calm when they are cornered!
The cool thing that the scientists discovered, is that the bighorn sheep who are more aggressive actually live longer! Pretty crazy, right?
So, are you aggressive or docile?
