| 158925733 | Jean Baptiste Lamark | Inhertitance of Acquired Characteristics-interaction between organisms and their environment, changes in trait are inherited (giraffe scenario) | |
| 158925734 | Thomas Malthus | most living things produce more offspring than can be expected to survive; competition for food and resources | |
| 158925735 | Darwin's Postulates | 1) There is the a "struggle for existence" b/c a population grows faster than its food supply 2) There is differential success to survive and reproduce 3) Variation in a population is present and is heritable | |
| 158925736 | Natural Selection | AKA: Differential Survival and Reproduction; when the environment changes, organisms that have characteristics that enable them to survive will do so and reproduce offspring with the same characteristics | |
