|---|---|

| how can chitin modified to serve an additional function? | Chitin is a long-chain polysaccharides that serves as an armor or cell wall |
| how were flippers of penguins modified for anew function? | the similar body structures but different ancestry of sharks and dolphins indicates that these groups have undergone |

| Fossil | animals that have later on in years turned into stone. |
| what is the fossil record? | is accumulation traces of animal pants. |
| basilosaurus fossils suggest that... | you can still find fossils but you cant tell really how old they are but you can estimate by the deepness of the fossil. |
| geographic distribution | This measures the range of separate geographic locations where infections have been reported |
| homologous structures. | Structures derived from a common ancestor or same evolutionary or developmental origin |
| vestigial structures | which is greatly reduced from the original ancestral form and is no longer functional or is of reduced or altered function |
| similarities in developments | evidence of relation between organisms through similarity in embryonic development |
| DNA sequence and molecular evidence | based on immunological distances |
| How do fossils form? | plant and animal remains that have been naturally preserved |
| relative dating of fossils | The calculated age of the tribe Sileas is indicated |
| continental drift. | Drift of the major continental blocks |
| george buffon ideas | ideas about the origins of the earth and other solar bodies, the processes |
| adaptation | a current functional role in the life history of an organism that is maintained and evolved by means of natural selection |
| jean baptiste lamarck ideas | that life might not have been fixed since creation |
| darwins observations aboard the hms beagle | observations leading to his theory of evolution |
| chareks lyell ideas | development of theories of geological and evolutionary change |
| thomas malthus ideas | if population was left unchecked, it could contribute to starvation |
| descent with modification | the passing on of traits from parent organisms to their offspring. |
| natural selection | the basic mechanisms of evolution, along with mutation |
| artificial selesction | the process by which humans breed other animals and plants for particular traits |
