Hmmm, sounds to me like evolutionists do not want to cover every possibility. Isn't that the point of science? Cover EVERYTHING. When looking at the facts, not half-truths and lies (from both creationists and evolutionists) evolution is undeniably wrong. Scientists will surely find Ardipithecus, and the other early humans on other continents, they just don't want to because it will, as done many times already, prove evolution obviously false. Evolution is wrong, as many theories of the past. Science and scientists needs to swallow its pride (or whatever is causing them to believe so foolishly in it) and move on and look for other answers.
