I just played with the generator. It accumulates mutations, yes.
What I don't see is mutated versions competing in any fashion against other mutated versions and/or the original.
Now, we do have models that do this kind of thing routinely. We use them to do a sort of hands-off Intelligent Design which often surpasses direct, hands-on human design. We call these ... (Wait for it!) ... Evolutionary Algorithms.
The author of this idiotic strawman simply took the evo algoritm concept, broke it so it doesn't work, and announced the downfall of Darwin.
Typical Cretin Science.
Natural selection is addressed at Randommutation.com about a fifth of the way down the page under the heading ...Now we add Natural Selection
"Typical Cretin Science."
Go to the link and look at the very bottom to have your point plainly debunked.
For instant example, you take great glee in putting down another freeper: "No, we do have models that do this kind of thing routinely. We use them to do a sort of hands-off Intelligent Design which often surpasses direct, hands-on human design. We call these ... (Wait for it!) ... Evolutionary Algorithms."
Just as that famous modern English Atheist did in his chapter on evolutionary stick-figures, your hubris causes you to miss where the "intelligent design" -- or "intelligent selection" rather than "natural selection", if you will -- is an intrinsic part of that methodology.
Who and what are the intelligent spirits -- the "selectors" -- in evolutionary algorithms? Why, you and I! The system designers who set out the playpen, or sand box, or whatever the program work area is called and decide on what the criteria are for winning!
It is that creation of the ground rules of operation and of the selection rules from generation to generation that our "spirits" impress themselves upon the random-appearing process.
