| 2447702674 | Evolution | A change in the genes over time |  | 0 |
| 2447704593 | Adaptation | Inherited characteristic of a species that develops over time in response to an environmental factor, enabling the species to survive. |  | 1 |
| 2447704594 | Punctuated Equilibrium | Populations stay stable for long periods of time, interrupted by brief periods of rapid change. Caused by environmental change or increased mutation rate. Supported by fossil record. |  | 2 |
| 2447705496 | Primate | A group of mammals that include all monkeys, apes, and humans. Characteristics include: opposable thumbs, arms move freely in shoulder joint, binocular vision, relatively large brains, some species make and use simple tools, complex social behaviors and family relationships. |  | 3 |
| 2447705497 | Charles Darwin | Father of evolution. Developed the theory of natural selection. |  | 4 |
| 2447706779 | Survival of the Fittest | The mechanism of natural selection. Individuals that are better equipped for their environment are more likely to survive and pass on their traits to offspring. |  | 5 |
| 2447706780 | Plate Tectonics | The theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. |  | 6 |
| 2447707888 | Hominoids | A group that includes all non monkey anthropoids- living and extinct gibbons, orangutans, chimpanzees, gorillas and humans. |  | 7 |
| 2447707889 | Hominin | Humanlike primate that appears to be more closely related to present day humans than to present day chimpanzees. Part of the larger hominoid group. |  | 8 |
| 2447708661 | The Beagle | The ship that Charles Darwin traveled to the Galapagos Islands on. |  | 9 |
| 2447709632 | Artificial Selection | The process by which humans breed other animals and plants for particular traits. |  | 10 |
| 2447709633 | Gradualism | Small genetic changes occur slowly within a population. Darwin's original description of evolution. |  | 11 |
| 2447711235 | Fossil Record | Fossils and the order in which they appear in layers of sedimentary rock. |  | 12 |
| 2447711236 | Bipedal | Using only two legs for walking. |  | 13 |
| 2447712705 | Natural Selection | The process whereby organisms better adapted to their environment tend to survive and produce more offspring. |  | 14 |
| 2447714527 | Population | A group of organisms living in the same habitat that belong to the same species. |  | 15 |
| 2447714528 | Species | A group of living organisms consisting of similar individuals capable of breeding. |  | 16 |
| 2447714529 | Mutation | A permanent change of the nucleotide sequence of DNA |  | 17 |
| 2447715553 | Divergent Evolution | Accumulation of differences between different populations which can lead to the formation of new species. |  | 18 |
| 2447716517 | Vestigial Structure | genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species, but have been retained through evolution. |  | 19 |
| 2447716518 | Analogous Structure | Structures with similar function but not common structure or common ancestor. |  | 20 |
| 2447717847 | Variation | Different or distinct form or versions within a species. |  | 21 |
| 2447717848 | Homo sapian | "Wise man" Modern day humans. |  | 22 |
| 2447718684 | Homo habilis | "Handy Man" Discovered in 1964 Used and made tools Direct ancestor to Homo sapiens |  | 23 |
| 2447719526 | Neanderthal | Closest extinct human relative. Fossils found in Neander Valley Germany. Lived in Europe, Asia, Middle East. Cold-weather adapted. Social structure, tools, buried dead, hunted. |  | 24 |
| 2447720877 | Australopithecus afarensis | Lucy, dubbed by some as the "Missing Link". The longest living hominin species. Shorter and more similar to chimpanzees. |  | 25 |
| 2447724827 | Homo erectus | "Upright Man". Migrated out of Africa into Asia and Europe. Taller with a larger brain. Built fires, wore animal skin clothing, lived in caves, made stone tools. |  | 26 |
| 2447724828 | Coevolution | The evolution of two species that are totally dependent on each other. |  | 27 |
| 2447725951 | Competition | a contest between organisms for territory, a niche, or a location of resources, for resources and goods, mates, for prestige, recognition, awards, or group or social status, for leadership needed for survival. |  | 28 |
| 2447727926 | Gene Pool | The total collection of genes in a population at any one time. |  | 29 |
| 2447737477 | Main Points of Natural Selection | 1. There is variation within a population 2. Some variations are favorable 3. Not all young produced in each generation can survive 4. Individuals that survive and reproduce are those with favorable variations |  | 30 |
| 2447786155 | Habitat | The place where a population lives. |  | 31 |
| 2448094812 | Homologous structures | Structures that are similar because of common ancestry but not necessarily common function. |  | 32 |
