1. Discussion Questions Discussion Questions 9/29/14 Journal 1.Please compare and contrast microevolution and macroevolution. 2.What is Adaptive Radiation? Convergent Evolution? Vestigial Structure? Give an example of each 3. A paleontologist is comparing the fossilized remains of two primates. Both animals had a prehensile tail. What can be concluded from this evidence? A. They were not related. B. They lived on the ground. C. They evolved from a common ancestor. D. They had bipedal locomotion.

2. Discussion Questions Discussion Questions 9/29/14 Journal 1. There are several ways speciation can occur. Please discuss the three isolating mechanisms (notes). 2. The frequency of the recessive allele in a population is 30%. What is the frequency of the dominant allele? What mathematical equation do you use to determine this?

3. Quick Notes about Natural Selection Four ways natural selection can act on a population 1. Stabilizing Selection where the average phenotype is selected for

4. Quick Notes about Natural Selection Four ways natural selection can act on a population 2. Directional Selection where one of the extremes in phenotype is selected for

5. Quick Notes about Natural Selection Four ways natural selection can act on a population 3. Disruptive/Diversifying Selection where both of the extremes in phenotype is selected for

6. Quick Notes about Natural Selection Four ways natural selection can act on a population 4. Sexual Selection- Based on the ability to attract a mate. Usually males and females differ a lot. Ex: Peacocks.

7. I. Natural Selection causes populations to evolve There are other mechanisms that cause evolution: II. Mutation III. Gene Flow (immigration, emigration) IV. Recombination of chromosomes during gamete formation AND V. Genetic Drift – which are just chance events. Bad luck not bad genes! Examples: A. Founder effect – where a small segment of a population is displaced to a new area B. Bottleneck effect- a natural disaster leaves a few survivors (hurricane, fire, tornado, flood, etc)
