1. Speciation, Macroevolution, and Microevolution

2. Microevolution
Process that cause changes in the inherited traits observed in a population over time
Natural Selection
Migration
Mutation
Mate Choice
Genetic Drift: Random effects of everyday life that cause differences in survival and reproduction rates

3. Macroevolution Process by which entire populations become new species.
This is the history of all organisms and their evolutionary relationship to one another.
Evidence shows that all species evolved over time from a common ancestor

4. Speciation
The selection of various adaptations can help lead to speciation
The formation of a new species
Species – Group of organisms that are closely related and can mate to produce fertile offspring

5. How does speciation occur?
Reproductive Isolation: When two species can no longer interbreed to produce offspring
Allopatric Speciation - Geographic Isolation
Sympatric Speciation – Same Place but Varying Mating Behavior and Timing

6. Macroevolution
Convergent Evolution: Species in similar environments have similar adaptations

7. Macroevolution
Coevolution: Species that alive in close contact often evolve adaptions to each other

8. Gradualism
Evolutionary change comes about gradually over time

9. Punctuated Equilibrium
Rapid change that results in a new species quickly

10. Extinction
All members of a lineage die off
