How does mass extinction differ from species extinction?
1 Answer
A mass extinction is when 50-90% of species go extinct whereas a species extinction is the demise of one species.
Explanation:
A mass extinction is when many species go extinct, and they are incredibly rare. Species extinctions are much more common and happen quite regularly. In the past decade, several species have gone extinct: the Yantze River dolphin, Pyrenean ibex, and the alaotra grebe are a few examples. Click here for more.
