| Evolution | A change in the genetic make up of a population or species over time |
| Population | The number of the same species in a given area |
| Species | Organisms that can produce fertile offspring |
| Fertile | One who can reproduce is known to be |
| Microevolution | A change within a species is |
| Macroevolution | A change among a species is |
| Lamarck | This person came up with the "The Theory of use and disuse" |
| Malthus | This Economist wrote an "Essay on the principle of population |
| Lyell | A Geologist who wrote the book "Principles of Geology" is |
| Darwin | "Descent with modification" is his theory |
| NaturalSelection | The process by which populations change in response to their environment |
| Isolation | The condition in which two populations of the same species are seperated from each other |
| Extinct | When a species disappears permanently it is known to be |
| Adaptation | The changing of a species that results in its being better suited to its environment is called |
| Fossils | Preserved or mineralized remains of an organism or traces of organisms that lived long ago |
| Paleontologists | Scientists who study fossils are called |
| Familytree | A diagram that is used to show evolutionary ancestry |
| CommonAncestor | A species from which two or more species diverged |
| HomologousStructures | Structures that share common ancestry are called |
| VestigialStructures | These structures have limited or no use |
| AnalogousStructures | These are structures with the same functions but different anatomy |
| Gradualism | Small changes over a long period of time is called |
| PunctuatedEquilibrium | Long periods of stability divided by sudden changes is known as |
| IndustrialMelanism | This is the darkening of populations of organisms over time in response to Industrial Pollution |
| BalancingSelection | Is a selection that acts in opposite directions |
| DirectionalSelection | Is a selection that acts in one direction |
| Divergence | The accumulation of differences between groups |
| Speciation | The process by which new species are formed |
| EcologicalRaces | Over time, populations of the same species differ genetically because of adaptations to different living conditions become what biologists call |
| ReproductiveIsolation | The prevention of mating between formerly interbreeding groups or the inability of these groups to produce fertile offspring |
