When reviewing Science texts, some good non-evolutionists distinguish "micro-evolution" below the species level (which they accept) from "macro-evolution" above the species level (which they reject). Evolutionists seldom stress this "micro-/macro-" distinction.
Instead, evolutionists say all "change over time" or "descent with modification" is evolution. This lets evolution mean two different things: shifts in gene frequency (e.g., peppered moths), and increases in net genetic complexity — one term for two separate concepts.
Why do evolutionists so define evolution? For the free-rider effect. Development of molecules to man gains plausibility by association if it falls under the same evolutionary rubric as simple genetic drift. But consenting to such forensic sleight-of-hand is folly.
It is folly tactically and scientifically. It puts you on the defensive playing your foes' game, which you should avoid. It spares evolutionists' weakness, which you should exploit. Evolution involves increased net genetic complexity. Subspeciation does not.
Subspeciation is not "micro-evolution." Pretending that it is, rewards evolutionists for definitional bait-and-switch. They will claim "macro-evolution" is just "micro-evolution" extended. If they define the terms of debate, your neck is in their noose.
Evolution requires increased net genetic complexity: between the first cell and Einstein there must be new genes. This definition stresses the failure to identify a mechanism for increasing net genetic complexity, which lets you control the discussion.
Newtonianism without the mechanism of gravity
would have been nothing.
Evolution
lacks a mechanism to increase net genetic complexity.
Therefore evolution is nothing.
