PCB evolution

Chapter 5

1)Irreducibly complexity only happens in intracellular molecular machineries.

1. This argument is based on creationist beliefs.
2. True.
3. False, it also happens in macromolecular complexes outside the cell.
4. Only true in prokaryotes.

2. Why is the understanding of the Theory of Evolution challenging?

1. Because it is a random process.
2. Because it constitutes a statistical process.
3. This theory is not challenging to understand.
4. Because it lacks testable predictions.

3. When is natural selection going to reach perfection?

1. Never.
2. During new speciation events.
3. After 1 generation of random mating.
4. After 2 generations of random mating.

4. Evolution by natural selection                    build molecular machines from                   .

1. does not/scratch.
2. does not/preexisting components.
3. cannot/preexisting components.
4. none of the answers is correct.

5. What is the argument for design?

1. The presence of complex systems in nature suggest the prevalence of natural selection during evolution.
2. The presence of complex systems in nature suggest alternative evolutionary mechanisms.
3. The presence of complex systems in nature suggest the presence of a designer.
4. The presence of complex systems in nature suggest complex evolutionary patterns.

6. Why does the US Supreme Court strike down the teaching of creation science and intelligent design in schools?

1. all answers are correct.
2. because they are not testable.
3. because they are against the first amendment of US Constitution.
4. because they are false.

7. Exaptation is…

1. none of the answers is correct
2. a shift in the function of a trait resulting in a fortuituous increase in fitness without selection
3. a shift in the function of a trait resulting in a fortuituous increase in fitness with selection
4. a rapid process of adaptation to external environmental conditions

8. The most controversial idea within the Theory of Evolution and the Modern Synthesis is…

1. natural selection
2. evolution
3. microevolution
4. speciation

9. The Modern Synthesis suggests that evolution is a                   process in which the origin of species is explained by                                   .

1. rapid/microevolution
2. gradual/macroevolution
3. gradual/microevolution
