The Dire Wolf Is Back

Science

Extinction is a part of nature. Of the five billion species that have existed on Earth, 99.9 per cent have vanished. The Late Devonian extinction, nearly four hundred million years ago, annihilated the jawless fish. The Triassic-Jurassic extinction, two hundred million years ago, finished off the crocodile-like phytosaur. Sixty-six million years ago, the end-Cretaceous extinction eliminated the Tyrannosaurus rex and the velociraptor; rapid climate change from an asteroid impact was the likely cause. The Neanderthals disappeared some forty thousand years ago. One day—whether from climate change, another asteroid, nuclear war, or something we can’t yet imagine—humans will probably be wiped out, too.
