I can't today, it's freezing out and my mom says I have to go home or else I'll freeze
Hey Nemo, do you wanna play tag? Its so warm outside!
Variation
Well Nemo and his mom are the last fish to remain in their family so they need to stay away from the cold so they dont freeze
-Not random-Not all individuals survive
Mom guess what? I asked Nemo to play tag and he said that it was cold and he couldn't play? Its warm outside
How come we don't freeze? And why is most of his family dead? How come he has different colored gills then me? And why isn't his blood white?
-Trait is heritable
That's because over time out ancestors developed a protein that acts as a anti-freeze and it was passed down through our DNA. Without it we would freezein the cold Arctic water
