Natural Selection- BEARS

Natural Selection- BEARS

Storyboard Text

  • There is a special mutation in our DNA that makes our claws sharp and strong enough so that we can climb to get more resources
  • Look there is some delicious honey for us to eat, but I don't have the special variation in my DNA that gives me sharp claws to climb 
  • I guess I'll just eat these ants
  • Since the mutation is chosen for in our DNA we are more likely to find food that gives us more nutrients and energy
  • I better save some ants until I find a different food source
  • Where's the nearest lake that has salmon
  • Over several generations of reproducing the trait of claws was passed down and chosen for and now almost all the offspring have sharp claws
  • My mother's parents had to either move away and find another resource for food or they would die.
  • This is what humans call natural selection. Its where variations in DNA that is chosen for, get passed down for many generations
