BIO 440: Population Genetics and Evolution

Study Questions - Patterns of Evolution II

1) Why is duplication such an important first step in evolutionary innovation?

2) Distinguish paedomorphosis from peramorphosis.

3) What is allometric growth, and how can it produce new evolutionary innovations and trends?

4) What biogeographical pattern did Wallace describe?

5) How did Darwin explain these patterns in terms of geographical isolation and speciation? In short, how would these processes produce the biogeographical patterns in taxonomy?

6) What is vicariance?

7) How can you test whether vicariance is responsible for the phylogentic pattern in a taxon?

8) What are unbalanced communities and how do they arise as a function of unequal dispersal abilities of species?

9) Be able to draw a nucleotide.

10) Link the nucleotide, above to a second and third one to form a nucleic acid.

11) Position a second strand next to your drawing from 10 to create a double helix.

12) Be able to describe how transcription and translation take place, and how their products are modified.

13) What is the difference between convergent evolution and parallel evolution? Give an example of each.
