Assignment:
Possible topics for discussion:
1. Is it possible to have the effects of linkage disequilibrium between two loci without physical linkage (with two loci far away or even on different chromosomes)?
2. Imagine a scenario in which measured heterozygosity in a wild population of mice is significantly lower than expected. What processes could explain the observed low heterozygosity? Give at least one example.
3. Some evolutionary biologists have suggested that the peripheral isolate model should lead to speciation faster than the dumbbell model. Why might this be the case?
4. "Exaptations are common, thus natural selection is not as important as evolutionary biologists think". Why is this statement not true?
