Theory {Ans: well-tested explanation that unifies a broad range of observations; cannot be proven but can be disproven}Patterns of embryological development {Ans: similar patterns indicate a common ancestry. Ex: fish, birds, mammals, are reptiles all have gills during development.}Embryology {Ans: the study of the stages of development before the birth of an organism}Fossil (image) {Ans: What evidence for evolution is this?}Comparative Anatomy {Ans: study of anatomical structures to find similarities.}Evolution {Ans: the process by which modern organisms have descended from ancient organisms}What can fossils tell us? {Ans: 1. organisms have appeared, disappeared, and changed over time. 2. extinction of species 3. ancient clime and environmental conditions 4. indicates development of life from simple to complex 5. indicates life began in water}Analogous Structures {Ans: structures of organisms have the same function but different structures. These organisms most likely evolved independently.}What do similarities in genetic molecules tell us? {Ans: 1. the more closely related organisms are, the more similar is the biochemical makeup 2. indicates a common ancestor. 3. universality of genetic code supports evolution.}Vestigial Structures {Ans: reduced body parts that have little to no function.}Analogous Structures (image) {Ans: What evidence
