Species is a group in organism that interbreed in nature and produce fertile offspring. Gaps though, bacteria don't sexually reproduce, and there are separate species that are able to mate and create fertile children.
|
|
|
|
Three types of species.
|
|
* Morphological Species:
|
|
* Studies shape, size, physics, structural features.
|
|
* Simple, quick.
|
|
* Most populations have variation.
|
|
* Biological Species:
|
|
* Ability to reproduce in nature and produce fertile offspring.
|
|
* Most commonly accepted definition, objective.
|
|
* Can't test on asexually reproducing, extinct, and/or physically separated organisms.
|
|
* Phylogenetic:
|
|
* Studies evolutionary history and relationships among organisms.
|
|
* Can be applied to extinct species.
|
|
* Not all evolutionary histories are known. |
