Here are 7 extinct wolf species and though some survived fearsome contenders like the saber-tooth tiger, none of them could contend with humans.
Worldwide, there are four species of wolves roaming in the wild today: the gray wolf (Canis lupus), the red wolf (Canis rufus), the Ethiopian wolf (Canis simensis), and the more recently ‘added’ African Golden wolf (Canis anthus).
In addition, there are several other subspecies scattered across almost every continent on Earth.
But did you know that there used to be many more wolf species/subspecies on Earth?
In fact, if you think today’s wolves are fierce, you need to read about some of their ancestors that were larger, fiercer, and probably even faster than modern day wolves.
