| 24298592 | Evolution | all of the changes that have transformed life over an immense time | |
| 24298593 | Adaptation | an inherited characteristic that improves and organism's ability to survive and reproduce in a particular evronment | |
| 24298594 | Natural Section | the process by which individuals with inherited characteristics well-suited to the environment leave more offspring on average than do other individuals | |
| 24298595 | Fossils | preserved remains or markings left by organisms that lived in the past | |
| 24298596 | Fossil record | the collection of fossils recorded in rock layers over time | |
| 24298597 | Extinct | species that no longer exist | |
| 24298598 | homologous Structures | similar structures found in different organisms with a common ancestor | |
| 24298599 | Vestigial Structures | homologous structures that have a major function in one species but not in a related species | |
| 24298600 | Descent with Modification | populations change over time | |
| 24298601 | Population | group of individuals of the same species | |
| 24298602 | Variation | differences among members of the same species | |
| 24298603 | Artificial Selection | selective breeding has resulted in many different types of domestic plants and animals, in a relatively short time | |
| 24298604 | Population Genetics | changes in the frequency of various genes in the gene pool | |
| 24298605 | Gene Pool | all of the genes of all of the individuals in a population | |
| 24298606 | Microevolution | changes in the gene pool. Small changes over relatively short periods of time | |
| 24298607 | Hardy-Weinberg Equilibrium | populations that do not undergo change to their gene pools are not presently evolving | |
| 24298608 | Antibiotics | drugs that kill or slow the growth of bacteria | |
| 24298609 | Genetic Drift | changes in the frequencies of genes in a small population caused by chance | |
| 24298610 | Bottleneck Effect | changes in the gene pool caused by a rapid reduction in population size. Reduces genetic variability | |
| 24298611 | Founder Effect | changes that occur in a small population that populates a new environment | |
| 24298612 | Gene Flow | addition of new genes to the gene pool by migration | |
| 24298613 | Mutation | creation of new genes by changing DNA. Increases genetic variation |
