Great mammoths, ground sloths, and sabertooth cats once thundered
across the plains of primordial North America. Then they mysteriously
disappered. Was this caused by climate change? By an asteroid impact?
By hunting by humans who arrived from Asia over the land bridge? No.
They were consumed and extirpated by the Pleistocene Drosera, capable of
snaring and strangling a woolly mammoth in its prehensile tentacles!
(The new human arrivals then killed these Drosera by overwatering and
pouring Superthrive on the traps).
