| Charles Darwin | Created the Theory of Natural Selection |
| Natural Selection | The process through which populations of living organisms adapt and change |
| The 5 rules | 1. All species have inherited genetic variation 2. Organisms produce more offspring than can survive 3. There is competition for finite environmental resources 4. Survival of the fittest 5. Descent with modification |
| rule #1 | All species have inherited genetic information. Every organism that is sexually produced is genetically different from the other |
| rule #2 | Organisms produce more offspring than can survive. This means that there are more organisms than the environment can support. Those that are better physically equipped survive, grow to maturity and reproduce |
| rule #3 | There is competition for limited resources. Since there aren’t enough resources to support every organism, competition for resources is present. |
| rule #4 | Survival of the fittest. Organisms best adjusted to their environment are the most successful in surviving and reproducing. |
| rule #5 | Descent with Modification of Populations. The organisms which survive eventually pass along the characteristics which helped them survive. Therefore over generations, those characteristics will become more relevant in the species. |
| Fossil records | The remains/imprints of organisms from earlier geological periods preserved in sedimentary rock |
| Lower layer | Older fossil |
| Index fossil | Used for relativity in relation to the other fossils to determine age |
| Almost all fossils are preserved in this | Sedimentary rock |
| Gradualism | Slow, gradual change of a species over time |
| Punctuated equilibrium | There are long periods of time with little to no change and then rapid spurts of evolutionary change occur |
| Homology | The state of having the same or similar relation, relative position, or structure Can be used to show |
