Final Jeopardy

1 - $100

Scientist that believed Earth’s geologic features formed as a result of gradual processes and Floods, earthquakes, and glaciers of the present do not cause great destruction of Earth’s surfaces.

Charles Lyell

1 - $200

Said that humans tend to produce more offspring than nature can support. Food production increases at a slower rate than population.

Thomas Malthus

1 - $300

Believed that Nature selects those individuals w/ favorable traits to leave more offspring that are better suited or FIT for their environmentDescent with modification occurs over time.

Each living species has descended, with changes, from other species over time

Charles Darwin

1 - $400

The oldest fossils are found in ______ rock

The oldest, more simple rocks are found in the lowest or highest layer?

Sedimentary and Lowest

1 - $500

The two ways to determine the age of fossils?

Relative Dating and Radioactive Dating

2 - $100

Animals that live in similar ecological conditions are exposed to similar pressures of natural selection. These animals evolve different characteristics. True or False?

False

2 - $200

Similar structures but different functionsStructures develop from same clump of embryonic

cells.

Homologous

2 - $300

Structures / organs that are reduced in size; do not seem to serve a useful function.

Vestigial

2 - $400

Because embryos of vertebrates are very similar in early development, the same groups of embryonic cells develop in the same order and in similar patterns to produce tissues and organs. This implies they share a common ancestor. True or False?

True

3 - $100

Adaptations being selected for increase an individual’s fitness in the environment

Natural Selection

3 - $200

5 requirements of Natural Selection

Variation, Over-population, Struggle for Existence, Fitness, and Adaptation over time

3 - $300

Helpful mutations lead to adaptation by increasing fitness and decreasing the death rate. What will happen to the frequency of the helpful mutation?

It will increase

3 - $400

How does natural selection apply to survival of the fittest?

The individuals that survive to reproduce more often have variations that are best suited to the environment (survival of the fittest). As the environment changes, favored traits and allele frequencies will change, causing the population to evolve

4 - $100

Consists of all genes, including all the different alleles that are present in a population.

Gene Pool

4 - $200

Random change in allele frequencies that occurs in small populations and doesn’t work to produce adaptations

Genetic Drift

4 - $300

The transfer of alleles or genes from one population to another; also known as gene migration.

Gene Flow

4 - $400

Members of an original species can no longer breed together to produce fertile offspring. They are considered 2 separate species.

Speciation

4 - $5001)___Two populations are capable of interbreeding but

have differences in courtship rituals or other reproductive strategies that involve behavior 2)____a barrier that physically separates members of a species into two or more groups. 3)____Form of reproductive isolation in which two populations reproduce at different times

1) Behavioral

2) Geographic

3) Temporal

5 - $100

1. Members at one end of distribution curve have a higher fitness than those in the middle or at the other end of the curve.

2. This type of selection favors average individuals and reduces variations in populations

3. When members at BOTH ends of the distribution curve have a higher fitness than those in the middle

1. Directional

2. Stabilizing

3. Disruptive

5 - $200

1. This can lead to the evolution of two new species.

2. Can lead to one population evolving into a new species

3. Reduces variation in a population; evolution is not likely to happen.

1. Disruptive

2. Directional

3. Stabilizing

5 - $300

What is the difference between gradualism and punctuated Equilibrium?

Gradualism- Long time with gradual change

Punctuated Equilibrium- Long, stable periods interrupted by brief periods or more rapid change

5 - $400

What is the difference between divergent evolution (adaptive radiation) and convergent evolution?

Divergent- type of evolution in which one species evolves into two separate species because it is adapting to different environmental situations

Convergent- type of evolution in which two unrelated species evolve similar characteristics because they are both adapting to the same environmental situations

5 - $500 What are the conditions to maintain genetic

equilibrium?

1. There must be random mating.2. The population must be very large. Genetic drift has less effect on large populations than on small ones.3. There can be no movement into or out of the population. Individuals may bring new alleles into a population.4. There can be no mutations.5. There can be no natural selection. No phenotype can have a selective advantage over another.

Final JeopardyImagine you’re given graphs that show the number of flies with different phenotypes or wing lengths. They live on an isolated island, where flies compete with one another for food. As a result, those flies with long wings fly 20 meters or higher off of the ground. Those with short wings fly less than 5 meters above the ground. Those with intermediate wing length fly at an average of 12 meters off of the ground. Which natural selection graph would show that the intermediate (average) length is more successful and is the most common length?

Stabilizing Selection
