| 1079241022 | Species | organisms belonging to a group of organisms that having common characteristics and are capable of mating with each other | 1 | |
| 1079241023 | Aquired Characteristics | Characteristics that an offspring inherits from its parents. | 2 | |
| 1079241024 | Natural Selection | a driving force in the evolution of a species that favors changes according to environmental conditions | 3 | |
| 1079241025 | Offspring | New organisms produced by a living thing, the product of the reproductive processes of an animal or plant | 4 | |
| 1079241026 | Theory | Rigorous and systematic formulation of the principles of science, philosophy, or any other form of knowledge | 5 | |
| 1079241027 | Adaptation | Is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats | 6 | |
| 1079241028 | Inherit | to receive (a characteristic) from one's parents by genetic transmission | 7 | |
| 1079241029 | Evidence | Is the proof used to reveal a theory. | 8 | |
| 1079241030 | Biodiversity | the variety or variability of living organisms in an environment | 9 | |
| 1079241031 | Habitat | the area or natural environment where an organism or community live | 10 | |
| 1079241032 | Speciation | The process through which a new species is born. | 11 | |
| 1079241033 | Evolution | A gradual process in which something changes into a different and usually more complex or better form. | 12 | |
| 1079241034 | Diversity | The genetic characteristics that distinguishes us from others. | 13 | |
| 1079241035 | Competition | The simultaneous demand by two or more organisms for limited environmental resources, such as nutrients, living space, or light. | 14 | |
| 1079241036 | Selection | A natural or artificial process that favors or induces survival and perpetuation of one kind of organism over others that die or fail to produce offspring. | 15 | |
| 1079241037 | Genetic Drift | reduction of alleles in a population (resulting from a disaster that drastically reduces population size). | 16 | |
| 1079241038 | Mutation | A change of the DNA sequence within a gene or chromosome of an organism resulting in the creation of a new character or trait not found in the parental type. | 17 | |
| 1079241039 | Gene flow | the gain or loss of alleles from a population by the movement of individuals (immigration or emigration). | 18 | |
| 1079241040 | Gene pool | The collective genetic information contained within a population of sexually reproducing organisms. | 19 | |
| 1079241041 | Microevolution | changes in the gene pool of a population over time which result in relatively small changes to the organisms in the population — changes which would not result in the newer organisms being considered as different species. | 20 | |
| 1079241042 | Macroevolution | changes in organisms which are significant enough that, over time, the newer organisms would be considered an entirely new species. | 21 |
