| Natural Selection | The process by which individuals that are better adapted to their environment are more likely to survive and reproduce than other members of the same species; a theory to explain the mechanism of evolution (survival, mate-finding, reproduction) |
| Genetic Variation | describes the different types of a gene that produce specific traits in a population of organisms |
| Fossil | Preserved remains or traces of an organism that lived in the past |
| Artificial Selection | Intentional reproduction of individuals in a population that have desirable traits A.K.A. selective breeding |
| Branching Tree | A diagram that shows how scientists think different groups of organisms are related |
| Evolution | a heritable (from parent to offspring) change in the characteristics within a population from one generation to the next; the development of new types of organisms from preexisting types of organisms over time |

| photosynthesis | Process by which specific organisms (including all plants) use the sun's energy to make their own food from carbon dioxide and water; process that converts the energy of the sun, or solar energy, into carbohydrates, a type of chemical energy. |
| Classification | The process of arranging organisms into groups based on similarities. |
| Taxonomy | The science of how living things are grouped together. |
| Scientific Names | The genus and species names create the scientific name (binomial nomenclature) |
| Dichotomous Keys | A chart used to identify the scientific name based on physical characteristics. |
| Prokaryote | single-celled with no membrane-bound organelles. Does not have a nucleus |
| Eukaryote | has membrane-bound organelles and does have a nucleus. |
| Autotroph | makes their own food |
| Heterotroph | has to find their food |
