We learn about natural selection.

Storyboard Text

  • Students today we will be learning about Natural Selection. The four parts of natural selection are overproduction, inherited variation, the struggle to survive, and successful reproduction.
  • We will be using dragons for our example. First we will look at overproduction. The gray dragons tend to have more children than the blue dragons, so more gray dragons survive.
  • Next up is inherited variation. The offspring are similar, but they aren't clones of their parents.
  • The dragons have to struggle to survive. Only the strongest, fastest, and smartest survive to pass on their genes to the gene pool. Since the gray dragons were the best adapted they had a successful reproduction.
  • Gray Dragons have been extinct for a while, but we know that the gray dragons were the most successful. This is thanks to Paleontology. We have found many fossils that belong to gray dragons, but none for the colored dragons.
