| Question | Answer |
| A characteristic that helps an organism survive and reproduce in its environment. | Adaption |
| A group of organisms that can mate with one another to produce fertile offspring. | Species |
| The process by which populations accumulate inherited changes over time. | Evolution |
| The solidified remains or imprints of once loving thing organisms | Fossils |
| A historical sequence of life indicated by fossils found in layers if the Earth's crust. | Fossil Record |
| The remnant of a once useful anatomical structure. | Vestigial Structure |
| The breeding of organisms that have a certain desired trait | Selective Breeding |
| A distinguished quality that can be passed from one generation to another. | Trait |
| The process by which organisms with favorable traits survive and reproduce at a higher rate than organisms without favorable trait. | Natural Selection |
| Natural Selection 4 Steps | Overproduction, Genetic Variation, Struggle to Survive, Successful Reproduction. |
| Each species produce more offspring than will survive to maturity. | Overproduction |
| Individuals in a population are slightly different from one another, each individual has trait that either increase or decrease their chances of survival. | Genetic Variation |
| A natural environment does not have enough resources to support all of the individuals born, in addition some are killed by other organisms. | Struggle To Survive |
| The key to natural selection, the individuals with better traits are more likely to survive and reproduce. | Successful Reproduction |
| A change in a gene. | Mutation |
| The process by which two population of the same species become so different that they can no longer interbreed. | Speciation |
| What are the three steps of speciation. | Separation, Adaptation, Division |
| When portion of the population becomes isolated (ex.newly formed canyons, mountain ranges and lakes) | Seperation |
| Once separated the environment can change, the species begins to adapt to their environment. | Adaption |
| Over hundreds of years the species can become so different they can no longer interbreed, even if the barrier is removed | Division |
