Wolves in Yellowstone

Evolution Unit Study

Lesson 11: We learned about the reintroduction of wolves to Yellowstone National Park.

The children's book Once A Wolf: How Wildlife Biologists Fought to Bring Back the Gray Wolf tells the story about how wolves became extinct in the American West and were later reintroduced. Shockingly it was laws that commonly encouraged practices which led to extinction. In 1995 scientists and biologists decided to reintroduce the wolves to Yellowstone. The population has since boomed and led to numerous ecological changes as discussed in the short video below.

Since one focus of evolution concentrates on the interactions between various species, this was a super end to our evolution study. It really brought home the idea that evolution is an on going process which is still happening today.
