New Darwinian Story: Our Jaw Differs From a Chimpanzee’s Jaw Because Our Ancestors Ceased Biting Their Enemies

Darwinian just-so stories are seldom if ever dull. 'Inventive' might be the word that best characterises them.
This week’s issue of New Scientist magazine features a series on lucky accidents that supposedly made us human. In its most orthodox variety, Darwinism has to rely on accidents, as it does not tolerate the existence of a Designer. Thus, mutations and natural selection ran the show.
Some of the explanations of how we became human are somewhat more absurd than the others. For instance: our jaw differs from that of a chimpanzee because our ancestors ceased using it as a weapon. In other words, they stopped biting their enemies.
Compared to such fact-free storytelling, the Genesis model sounds very rational, with no need for outlandish explanations.
