In their clarification via exclusion of biological facts , they noted that “…speciation by chromosomal rearrangements is also known to occur in yeasts and mammals…” Therefore, if you don’t have a problem with eliminating Darwin’s ‘conditions of life’ and proceeding to discuss mutation-initiated natural selection and speciation that incorporates mutations that are supposedly somehow fixed in DNA and are also beneficial, feel free to continue discussing evolutionary theory as if you knew something about it that could be compared to the biological facts of ecological adaptation.
In any case, the biological facts haven’t changed since Darwin’s time. Perhaps that’s why Darwin stressed them rather than simply making claims based on mathematical models.

This was an early example, which Bill Moyers noted, of how medical practitioners ignored what they had learned about mutation-driven evolution and treated the patient based on animal models of biologically based cause and effect involving the neural, endocrine, and immune processes of ecological adaptations, which are not like mathematical processes responsible for the nonsense of the partisan divide on evolution.
