  • Overproduction
  • Variation
  • Environment
  • A thick coat bear and a thin coat bear reproduce and have three cubs. Two of them have thin coats and one cub has a thick coat.
  • Struggle
  • There are two variations of bears, thin coat bears and thick coat bears.
  • Selection
  • The bears live in a cold and snowy forest.
  • Differential Reproduction
  • The bears with thin coats are dying from the cold.
  • The bears with thick coats survive the cold because they are warm.
  • The bears with thick coats survive long enough to reproduce with other bears with thick coated bears. Over time there are more bears with thick coats then thin coats.
