"No species but man, so far as is known, unaided by circumstance or climate change, has ever extinguished another, and certainly no species has ever devoured itself, an accomplishment of which man appears quite capable."
-Peter Matthiessen
Advertisment
The contagious cancer that is decimating Tasmanian devils probably isn't being counted as a species, but the devils may soon go extinct anyway.
It is arrogant to assume no other species has eradicated another species, simply on the basis that nobody kept records of such developments.
Most species that ever existed are long gone. What wiped them out, mass suicide?
Is today National Troll Day or something? Why didn't someone tell me?
