Term
| What are the main points of Darwins theory of Selection? |
|
Definition
| Individuals in a population have variable levels of agility, size, ability to obtain food, and different successes in reproducing. Left unchecked, populations tend to expand exponentially, leading to a scarcity of resources. In the struggle for existence, some individuals are more successful than others, allowing them to survive and reproduce. Those organisms best able to survive and reproduce will leave more offspring than those unsuccessful individuals. nOver time there will be heritable changes in phenotype (and genotype) of a species, resulting in a transformation of the original species into a new species similar to, but distinct from, its parent species |

| What are the 6 Mechanisms for reproductive isolation? |
|
Definition
| Geographical: ex. Grand Canyon (North and South Kaibab Squirrel) 2.Ecological: organisms live in different environments 3.Temporal: Organisms reproduce at different times 4.Behavioral: different courtships of species 5.Mechanical: structural differences prevent mating 6.Reproductive failure: offspring is sterile. Ex. Horse + Donkey = Mule |
