I'm talking with an Intelligent Design advocate who linked me to an article claiming that the nested hierarchy (morphological, I guess) has fatal problems in it -- for instance, the "flat face" of Sahelanthropus tchadensis and Diania, an early arthropod or ancestor thereof.
I can imagine several responses, I wonder which apply:
1. A few organisms that don't fit into the hierarchy doesn't cause the entire edifice to crumble. But wouldn't it merely take one or a few outliers to falsify the nested hierarchy as a predictive model in evolution? Or not?
2. These organisms don't cause a problem for the hierarchy because their place in the hierarchy is still being debated.
3. These organisms fit into the nested hierarchy without any problems.
Comments?
