“Apologetics Press” is satisfied that Ardipithecus is nothing that will cause them to change their preconceptions:

While Ardipithecus ramidus kadabba undoubtedly will stir controversy among evolutionists as to exactly where it fits into the “evolutionary family tree,” it does little to answer the questions of “how apes became human,” or when and why these creatures became bipedal. Given the small measurements of the fossilized bones collected, kadabba is very likely to find itself relegated to the same branch as the infamous Lucy (Australopithecus afarensis)—simply a fossilized ape.http://www.apologeticspress.org/articles/2060
