Question

part a
a scientist studying these walking sticks claims that the two populations are likely to evolve into two separate species over time.
would you accept or refute this claim?
a accept
b refute
part b
identify which piece of evidence would best support your answer to part a.
a the two populations both feed on plants.
b the two populations live in the same ecosystem
c the two populations live in different regions of the ecosystem
d the two populations are less likely to reproduce with each other

Explanation:

For Part A: If two populations are in different regions (as in Part B's option C), over time, they may experience different selective pressures. This can lead to genetic divergence. For example, in different habitats, different traits may be favored. If this continues, they may become reproductively isolated (as in Part B's option D) and evolve into separate species. So we accept the claim in Part A.
For Part B: Reproductive isolation (option D) is a key factor in speciation. If two populations are less likely to reproduce with each other, over time, genetic differences can accumulate, leading to the formation of separate species. Options A (same food source) and B (same ecosystem) do not promote speciation. Option C (different regions) can be a starting point, but reproductive isolation (D) is more directly related to speciation.

Answer:

Part A: A. Accept
Part B: D. The two populations are less likely to reproduce with each other
