Charles Darwin | published evidence that species evolved, and explained how evolution occurs |
Galapagos Islands | islands off the South American coast where Darwin first observed evolution |
Theory of evolution | 1. Inherited variation exists within the genes of a population 2. Natural selection 3. Those traits tend to spread in that population 4. There is evidence from fossils that living species evolved from organisms that are extinct |
