No one would take that bet because no one would be silly enough to think anyone thought that's what evolution is. While that may be YOUR definition, it is not the one in practical use. And I have been specific in what was was contending against - that evolution caused speciation. Also, that evolution is NOT variation in species - if that's the case then every reproduction is evolution because I would imagine rarely (if ever) do the offspring have the exact characteristics of both of the parents. So your definition becomes a meaningless if it means what you say it does.

It is not me who has done so - it is the scientific community that has made it so, whether by mis-use (as you imply) or because that was the meaning all along. Either way, this is it's common meaning and is what is being discussed here. Usually people who have no argument change the argument to one they can win. In this case, you didn't even do that.
