A. Describe the relationship between and island's size and the probability of extinction over time. 
B. How does natural selection and genetic drift lead to evolutionary change on island and mainland environments.

I think: the bigger the island, the more resources available needed for survival.
For the second one:
- natural selection: only the most adapted species will remain
- genetic drift is the change in frequency of an allele.
