Most certainly. Its an example I have often used here in the forum of a benefical mutation.Is this an example of environmental pressure that causes microevolution?

Mostly, yes.Do you agree with this paragraph from your link?
Don't know about fast-forward. There is a strong selection pressure applied, so the results of evolutionary mechanisms are easier to see.Do you agree with this paragraph from your link?
This has been very well tested. Of course back when they tested it they called it Agent Orange.Is this an example of environmental pressure that causes microevolution?

To just drive the point home of how different they are.Agent Orange and Round up use two completely different chemicals.
Has there been any studies looking at the mechanism behind glyphosate resistance? Is it just a change in the enzyme it's suppose to inhibit?

Agent Orange was also contaminated with TCDD. Note that these are all chlorinated hydrocarbons.
