Yawn. North America during the last glacial maximum killed off most of the tropical fauna and vegetation.

Between exotics and uninterrupted vegetative succession, our property was down to 60 plant species. With careful management and control of exotics, that number is now 400.

Exotic species are the single most powerful force causing mass extirpations, more than development. Yawn all you like, but the rate of differentiation will never match the rate of displacement.

Green bean idiots are always trying to freeze the current conditions on earth in place. If you lived 12,000 years ago you would have been trying to save the Laurentide ice sheet that covered all of Canada. You are in good company with the climate change alarmists.

And how many species of predatory flatworm is it home to?

We'll wait while you count.

“but the rate of differentiation will never match the rate of displacement.”

It eventually does, and has throughout earths history. It’s commonly referred to as “Adaptive Radiation”
