Where did the gray wolf live?

The gray wolf (Canis lupus) has a wide historical range across the Northern Hemisphere. They were once found in a vast area covering much of North America, Europe, and Asia.

Here's a breakdown of their historical and current ranges:

Historical Range:

* North America: From Alaska and Canada to Mexico, including most of the continental United States.

* Europe: Across most of the continent, from Scandinavia and Russia to the Iberian Peninsula and the Balkans.

* Asia: From eastern Russia and Mongolia to the Arabian Peninsula and Southeast Asia.

Current Range:

Due to habitat loss, hunting, and persecution, the gray wolf's range has significantly shrunk. They are now found in:

* North America: Primarily in Alaska, Canada, and the northern and western United States.

* Europe: Scattered populations in Russia, Scandinavia, Eastern Europe, and the Iberian Peninsula.

* Asia: Across Russia, Mongolia, China, and parts of Central Asia.

Reintroduction efforts have been successful in restoring gray wolf populations in some areas, such as the Yellowstone National Park in the United States. However, the gray wolf still faces challenges, including conflicts with humans and livestock.
