Recent molecular evidence suggests that the ancestors of the Aboriginal Australians may have arrived on that continent much earlier than originally thought, suggesting that there may have been two waves of human migration out of Africa instead of only one. What is the best next step for scientists considering this alternative explanation? (2 points)
Group of answer choices:
Look for fossil evidence that might support this explanation.
Determine the amount of popular support for the theory.
Convince the scientific community the new explanation is true.
Assume the molecular evidence is wrong since it does not fit with what is known.
