Darwin's theories

  • Evolution:species gradually change over generations, better adapted
  • Natural Selection: better adapted species more likely to survive
  • Survival of the Fittest:survivors pass strong traits to offspring
  • Overproduction, Competition
  • Variations-differences in same species
