Arizona's 10 Coolest Contributions to Science
1.) The Grand Canyon
The Grand Canyon is a natural scientist's dream come true. There are more than 373 bird species, 89 mammal species, 47 reptile species, 9 amphibian species, and 17 fish species. There are more than 1,700 known species of plants, along several different ecosystems.
It's "one of the most studied geologic landscapes in the world," according to the National Park Service.
"Its great biological diversity can be attributed to the presence of five of the seven life zones and three of the four desert types in North America," according to the Park Service. "The five life zones represented are the Lower Sonoran, Upper Sonoran, Transition, Canadian, and Hudsonian. This is equivalent to traveling from Mexico to Canada."
