If the Darwinian package were correct, then we would expect to see the simultaneous appearance in the archeological and fossil records of evidence for bipedality, technology and increased brain size. We don't.

We are justified in calling all species of bipedal ape "human." ...the adaptation of bipedalism was so loaded with evolutionary potential—freeing the upper limbs to be free to become manipulative implements one day—that its importance should be recognized in our nomenclature. These humans were not like us, but without the bipedal adaptation they couldn't have become us.

The French archeologists Iégor Reznikoff and Michael Dauvois conducted detailed surveys of three decorated caves in the Ariège region of southwest France. ...they moved slowly through the caves, stopping repeatedly to test the resonance of each section... spanning three octaves... those areas with highest resonance were also those most likely to harbor a painting or engraving. ...a fascinating discovery that...
