| How does variation within species happen |
|
Definition
| As environment changes certain specimens of an organism begin to have adaptations that are useful and help it survive. These adaptations will be passed on to further generations, |
|
|
Term
| What is the benefit of variation within species |
|
Definition
| Variation within species allows the species to survive bad conditions like a weather change or a disease. Certain organisms with certain adaptations will survive becuase of the variation which helps the species not become extinct after certain hardships. |

| Are generalist or specialists more suseptable to extirpation vs extinction. |
|
Definition
| Generalists are more susceptible to extirpation because of the variation it won't kill the entire population but it could in one location. Specialists don't have the ability to adapt or have variation so if a specialists species is dying off it is likely the whole population will die. |
