Very good point.
Concerning language, we have a good record on the evolution of English.
However, it didn't become a new sort of language ~ just another transformation of a synthetic to an analytic language type.
Sometimes analytic languages become synthetic, or part of a synthetic language.
In biological terms this would be like cats turning into dogs, and dogs turning into cats.
Biological evolution doesn't work that way and is conceptually unable to be applied to linguistic change.
Yeah, I also questioned the darwinist's claim that no new lanquages had been observed. What about Pig Latin? Or Jive? Or Technical Jargon? Clearly language is evolving and rapidly. English today is dramatically different than English 600 years ago. That claim can't be made for animals or plants.
Don't tell me birds cannot evolve!
The Ford Falcon evolved into the Mustang!
"Oh, yes, the market value of evolution is........?"
Giving people an excuse to discount the existance of God?
