Special Topics in Evolution True or False

1. Which of the following best describes this phylogenetic tree? -> Cladogram
2. What is feature A indicating? -> Inferred Ancestor
3. What is feature B indicating? -> Character change
4. Which two species have the most recent common ancestor? -> Dog and cow
5. Which of the following species is in the outgroup? -> Human
6. Say there are two genes for humor in humans, a ShmP and ShmO gene. Which of the following terms best describes the process of the ShmP gene mutating to pick up a portion of ShmO gene? -> Disruptive selection
7. Which of the following terms best describes the process of selection driving individuals to carry only the ShmP1 or ShmP3 allele of the ShmP gene, but not the intermediate allele ShmP2? -> Disruptive selection
8. Which of the following terms best describes the similarity between the ShmP1 gene that is only found in humans and fruit flies (and no other species)? -> Convergent evolution
9. You notice a two species on either side of a mountain range. They both look very similar to each other, and when you do a phylogenetic tree, you find that they are genetically similar to each other, but clearly two different species. How did they arise? -> Allopatric speciation
10. What process best describes the individual mutations that a virus might pick up to gain drug-resistance? -> Genetic Drift
