Given its broad phylogenetic perspective across species with widely different features, the MH hypothesis is admittedly difficult to test with comparative data. … Unfortunately, the procurement of direct estimates of Ne remains dauntingly difficult , and until this problem is solved, it will remain difficult to obtain unbiased estimates of the key parameter Neu. However, there is no justification for rejecting a theory based on its accessibility to formal hypothesis testing.
Evolutionists insist on strictly naturalistic explanations. That makes evolution—broadly construed as the origin of species via natural laws and processes—the right answer. Evolution can be modified by rejecting old sub hypotheses and erecting new ones, but the core idea cannot be wrong. Now even evolution’s sub hypotheses can also be untestable.
