Definition
| First came up with a comprehensive and mechanistic theory of evolution: inheritance of acquired characteristics. use and disuse (later proved incorrect). |

Term
|
Definition
| attempted to classify lifes diversity fo"for the greater glory of God". Developed the system of naming organisms according to genus and species. by grouping similar species into increasingly general categories. |

Definition
| introduced unifortarianism-mechanisms of charge are constant over time. Same geologic procceses happening today as in the past and at the same rate. |

1) descent with modification
2) artificial and natural selection and adaptation (selective breeding=artificial selection) |

Term
| Darwin's four observations |
|
Definition
1) members of a population var greatly in their traits
2) traits are inherited from parents to offspring
3) all species are capable of producing more offspring than their environment can support.
4) owing to lack of food or resources many of these offspring do not survey.
infereces: individuals with traits better suited for surviving leave behind more offspring. this unequal ability of individuals to survive leads to favorable traits in the population over time. |

Term
| natural selection is a reaction between: |
|
Definition
| a population and the environment (not an individual) |
|
|
Term
|
Definition
| Related species that have characteristics with an underlying similarity even though they may have very different functions (resulting from a common ancestry) |
|
|
Term
|
Definition
variations on a structural theme that was present in a common ancestor
ie: human arm, cat leg, whale fin-forelimbs of all mammals (all bones have same general structure) |
|
|
Term
|
Definition
| remnants of features that served important functions in the organisms acceptors (snakes have leftover bones from the pelvis and leg bones of walking ancestors) |
