Arizona. December 2025. It is such an article of faith among most university professors that it passes as settled science: the notion that the earth is currently experiencing a mass extinction. Some government-supported (and supporting) “scientists” even claim that the world is currently in a “fourth,” “fifth,” or “sixth” “mass extinction. Of course, these self-identified scientists invariably claim the cause of this alleged mass extinction is capitalism, overpopulation by humans, or the burning of fossil fuels.
Now a new study by Kristen Saban and John Wiens of the University of Arizona Department of Ecology and Evolutionary Biology shatters these notions. The study, published in Proceedings of the Royal Society, revealed that over the last 500 years extinctions in plants, arthropods and land vertebrates peaked about 100 years ago and have declined since then.
