What would happen if wolves were removed from Yellowstone?
Removing wolves from the park affected much of Yellowstone because wolves are top predators and arguably keystone species. ... Wolves feed on elk, and without the wolves, the elk population exploded. The elk fed on young aspen trees, so the park had very few young aspen trees.
What happened to Yellowstone when the wolves left?
In the 70 years of the wolves' absence, the entire Yellowstone ecosystem had fallen out of balance. Coyotes ran rampant, and the elk population exploded, overgrazing willows and aspens. Without those trees, songbirds began to decline, beavers could no longer build their dams and riverbanks started to erode.

When did wolves almost go extinct?
The gray wolf was almost extinct in the lower 48 states of the United States by the mid 1900s. Thanks to the Endangered Species Act, the gray wolf may be well on its way to recovery.

Evolution of foxes, wolves, and dogs
Scientists believe that the closest ancestor of all modern dogs is the modern-day gray wolf. As cousins to wolves and dogs, foxes are a great model for dog domestication. They diverged from the wolf lineage about 12 million years ago (a brief time period, evolutionarily).
