The funny thing is that he gets so incensed when we call out the fact that the term “evolution” is being conflated to mean both “change over time” (which is correct), and
goo-to-you, particles-to-people, molecules-to-man “evolution”.
The conflation is on purpose. It hides the illogic of
“Given: species change in response to enviromental pressure.
Conclusion: goo-to-you is true”
Also, wrt your “next step in the evolution of mankind” - that assumption MUST be addressed, because it totally devalues what we are NOW as “inferior” to some future superman, and invariably leads to programs of “guided evolution” or eugenics.
Erosion is a process. Mountains and valleys are a result of that process. Erosion and Mountains cannot be said to be the same thing - although they ARE related.
Moreover we are still discussing HOW adaptive change in response to environmental pressures is carried out - isn't it you whose described model needed all useful variations of DNA that ever existed and ever will exist within a population to be put into the primordial “kind”? Have you any idea how impossible that is using actual real and non-miraculous molecules?
Evolution changes. It adapts. Adaptation to new conditions doesn't make one “superior” and the previous adaptations to previous conditions “inferior”. Evolution doesn't unambiguously improve things. A race horse is not fast - and just as good as a normal horse at everything else - a race horse is fast at the EXPENSE of sturdy legs that don't break and thick skin that doesn't crack.
Once again, Eugenics is to Evolution as Socialism is to Free-Markets. Both see a highly productive system with millions of individual actors pursuing their own self interest - and think that centralized authority had better crack down on that right away - because they know better than “the market” what is desired.
Eugenics could work in a totalitarian society to breed smarter humans, or stronger humans, or healthier longer lived humans - but always at the expense of something else.
Despite the empty promises of Socialism and Eugenics “There is no such thing as a free lunch.”.
Which gets us right back to the heart of this thread.
