Well, no, I think you are the one confused.
The term "Natural Selection" was the original theory backing up Evolution as described by Darwin. It is a process where nature favors a particular species trait for reproduction so that eventually the species changes in favor that trait. Enough accumulated generations of "natural selection" and a new species will result.
This is argued against by creationists who claim that so called "macro-evolution" could not happen. They give no mechanisim for WHY accumulated traits will stop at some limit, they merely claim that because only a limited amount of Evolution has been observed in the last 200 years, then that must be all there is.
Scientists believe that such an artificial wall limiting the effects of natural selection does not exist. Creationists have been unable to describe a mechanism for this supposed wall and have produced no evidence for it.
Which goes back to my original point that NEITHER of these theories is falsifiable
Creationists didn't start talking about falsifiability, until it was pointed out that faith in an omnipotent god could explain everything, and was thus non-falsifiable. Any observation could be explained by the magic words, "God did it".
Evolution, on the other hand, has several methods of falsifiability. One could find evidence of recent species in old fossil layers. Or, one could find old and new fossil types mixed in the same layer. Or, once DNA was isolated, it could have disagreed with Evolution theory. But amazingly, it verified Evolution, a hundred years after Darwin.
All it would take is ONE such find that would falsify Evolution as described above, and Evolution would have a serious problem. The fact that despite concerted efforts of creationists with money to spend and time to burn, they have not found even one magic fossil that would cause serious questioning of evolution.
That Evolution has withstood such intense examination for so many decades by such determined people is the reason I am so certian of it.
The fact that despite concerted efforts of creationists with money to spend and time to burn, they have not found even one magic fossil that would cause serious questioning of evolution.
I would posit that the professional creationists don't really want to falsify Evolution. Like the Egyptologists that don't really want to discover how the pyramids were built, once the creationists falsify Evolution completly, what will they do for a job?
They are not employed as regular scientists. Their money comes from donations from congregations and sales of media products. If everyone accepted their theories, then those money sources would dry up.
Creationists depend on a never ending argument. Kind of like lawyers.
Thank you, thank you. Thank you for saving me the time of having to type my own explanation. That was excellent, very well rounded.
