Evolution Flashcards
Person: thought of natural selection
Charles Darwin
Galapagos island showed…
Biodiversity
Fulfilling a specific purpose
Niche
Natural selection is…
Nature selects what lives in an area, nature environment
Evolution is…
Descent with modification through genetic inheritance
Theory of Evolution 4 Parts
- Overpopulation
- Variation
- Selection
- Adaptation
Gene pool is…
The genes in a population
How often B and b show up is…
Allele frequency
Hardy Weinberg Law (5 Parts)
- No mutations
- Large population
- Random mating
- No immigration
- No selection pressure/natural selection
Gene drift is when…
allele frequencies change over time
Bottleneck vs. Founder Effect
Explain…
Species is…
- a group that evolves independently
- has offspring
The two speciations are…
- Allopatric (barrier)
- Sympatric (no barrier)
Pre-mating isolation vs. Post-mating isolation is…
…
When you _____, you _____
survive, reproduce
The 3 types of adaptations are…
- Morphological
- Physiological
- Behavioral
The 2 types of coevolution are…
- Mutualism
- Predator/prey
When the curve goes to the MIDDLE it is…
Stabilization
When the curve goes to the EXTREMES it is…
Directional
When the curve avoids the middle and favors BOTH EXTREMES it is…
Disruptive
When the heterozygous gene is best it is called…
Heterozygote advantage or Balanced Polymorphism
