Generations for mice are measured in months, not decades. Your problem is that you are thinking in anthropomorphic terms.
Noone is saying that evolution happens at a fixed pace for all species. There's micro evolution and there's macro evolution. Certain species reproduce faster, so of course the rates of their micro and macro evolutions increase. These changes still happen in considerable time. Thousands of years, tens of thousands of years, hundreds of thousands of years, millions of years.
Evolution happens in every birth, but that is microevolution, and concerning the changes in the alleles of the species.
The notion that you made earlier, was a total joke and you know it. You just don't sound very educated when it comes to evolution.
The single point I'm poking at in the original post of yours I quoted, is that you said "this happens in a
few years. Microevolution DOES NOT produce changes significant enough in a few years(except in protozoa) to be considered to have EVOLVED into the voided niche.
On the contrary it's a matter of that species having already been evolved to fill that niche, except they could not compete or were not already present in the environment.
You can't ******* kill off any known predators of a particular invasive species, introduce that invasive species, and when it thrives say that it recently evolved to adapt to that environment. No... it was ALREADY evolved to thrive in that environment, it just no longer has the threats or competition to stop it.
