Definitions
Types of NATURAL SELECTION
- Stabilizing
- Disruptive(diversifying)
- Directional
Homologus structures
- Dif functions(maybe)
- Same structure
- Evidence of common ancestor
Analogous structures
- Same function
- Dif structure
- NOT evidence of common ancestor
Darvin’s theory of Natural selection
- Populations tend to grow exponentially to overpopulate and exceed their resources
- Overpopulation results in competition and struggle for exitence
- Variation and unequal ability of individ to survive and reproduce.
- Survival of the fittest
Divergent evolution
Population become isolated, new species appear
Convergent evolution
Two different species become similar regard the same conditions
Parallel evolution
Two related species made the same evolutionary adaptations after their divergence from a common ancestor
Coevolution
Mutual evolutionary set of two interacting species.
Pollinator-plant
Adaptive radiation
Emergence of numerous species from a single common ancestor.
Conditions for Hardy-Weinberg Equilibrium
- No mutations
- Random mating
- No natural selection
- Large population size
- No gene flow
Vestigal structures
Useless however had an ancestral function
