Essay

Refer to the figure.
Figure 3
Figure 3 shows long-term patterns of continental movement for five large land masses, illustrating the location of the land masses during an active period of land mass movement, at about 40 mya. The arrows indicate the direction of land mass movement and the numbers indicate the approximate timing (mya) of these events. Based on the movements of these land masses, answer the following questions about how the movements might have affected the evolutionary history of the resident species:
a) What evolutionary phenomenon likely occurred when land mass 2 split from land mass 4? Give the name of this concept and explain it as it applies to the splitting of land masses 2 and 4.
b) What additional information would you need to more confidently predict how the split of land mass 2 from land mass 4 would have affected the populations on each of these land masses?
