Somehow random mutations creating an incredibly complicated set of bones, muscles, teeth, and behaviors, with “extremely precise” functions, all of which “likely” arose independently rather than through common descent, just doesn’t sound right. So as usual evolutionists view the problem teleologically. According to the latest study of the mammalian jaw, it seems that “mammal teeth, jaw bones and muscles evolved to produce side-to-side motions of the jaw, or yaw, that allowed our earliest ancestors to grind food with their molars and eat a more diversified diet.”

To produce?

As we have seen numerous times, the infinitive form tells all. Aristotelianism was not rejected, it was incorporated.

But how could such interdependent complexity evolve in the first place? The jaw, dental, and ear characters comprise so many highly complex, moving parts that need each other to work. And furthermore, they appear in different lineages. The answer is simple: simultaneous, concurrent, convergent evolution.

Based on results of the morphometrics and functional analyses, I develop a novel hypothesis for the simultaneous origin of unique jaw, dental, and ear characters in cladotherians. […] Here, I examine concurrent evolutionary changes to functional anatomies of jaws, molars, and ears in early cladotherian mammals […] The jaws, molars and ears of australosphenidans (which include monotremes) are morphologically similar to those of therians, suggesting convergent evolution of similar functional traits in this group.

All of this, the study concludes, “may have been an especially significant event in mammalian evolution.” Indeed. But for a paper titled “The evolutionary origin of jaw yaw in mammals,” there is remarkably little explanation of just how this design evolved.

The bottom line is the evidence does not fit the theory. If the answer is simultaneous, concurrent, convergent evolution, then let’s just admit the obvious.
