Why Evolution? | Reproduction Isolation | Allopatric Speciation | Sympatric Speciation | Law of Competitive Exclusion | niche |
---|---|---|---|---|---|
-Genetic Engineering of food (conventional and new molecular techniques) -Human Health (environmental health and toxicology) -Biodiversity | Isolation prevents gene flow between members of a species | Speciation due to geographic separation | Speciation that does not require geographic separation mechanical: structural differences temporal: different timing for breeding behavioral: courtship displays ecological: different ecological roles resource partitioning | Law that states no two species will occupy the same niche and compete for the exact same resources for an extended period of time -one will migrate/become extinct/sub-divide resource utlization (Darwin's finches) | a description of the role a species plays in a biological community, or total set of environmental factors that determines species distribution |
