Your example would be a lot more relevant if evolutionary theory actually was problematic. As it is, we have a constant influx of research that verifies Evolution.
It seems (although I am not a YEC) you do have a flaw in your assertion in that statement. What does exist is an influx of new research, which you are correct on that, but the new information causes a modification to any number of the smaller theories that are compiled into the conglomerate of the Theory of Evolution. If a theory must be modified in order to remain valid, that would mean that the underlying hypothesis which produced the originating theory would have been falsified. A falsification in any number of the theories within the conglomerate theory does not however falsify the conglomerate as a whole.
Some observations that I have made are likely to make both camps mad, but they are an interesting amalgamation of pure observances.
1) Just because there are 7 days listed for creation in Genesis does not mean they occur in the same week, year, millenia or any other measure of time.
2) Evolution does occur but is most likely unrepeatable as determinate factors may be compound and unobserved.
3) Not all unfalsified hypotheses are true
4) The possibility of an occurrence and the probability of an occurrence does not indicate that an occurrence actually happened.
5) Even in collegiate texts the words or phrases "most likely" or "probably" or my favorite "possibly" are used unsparingly in biology texts.
6) Science admits there is still much to learn yet believes that what is knows now is enough to theorize with or about.. At one point the greatest civilization on Earth, the Egyptians, thought the brain just produced mucos so they removed it and destroyed it during mummification. 100 years ago they did not know we had a planed named Pluto, wait that is not a planet anymore, well anyway, they did not know it was there.
Now back to your regularly scheduled squabble!
