A Test of Common Descent vs. Common Function

This is one test of the superiority of phylogenetic hypotheses to separate creation/function hypotheses. It’s far from the only one, but it’s novel, and consilience is always nice.

It does not appear to suffer from the same pitfalls as the tests that are actually billed as common descent tests. This one, for example, seems to fail (Beyond Reasonable Doubt? A Test for Common Ancestry).
