What Killed the Woolly Mammoths?

"Mammoths & Mastodons" Exhibit at Field Museum

I always learn something new at a great museum like Chicago's Field Museum, and today's visit was no different.

Going through the new "Mammoths and Mastodon" exhibit, I learned that there are five primary theories about what killed the mammoths and mastodons, the last of which disappeared in Siberia about 3,000 years ago:

1. Climate Change
2. Disease
3. Over hunting
4. A meteorite
5. Goldman Sachs

Apparently, scientific evidence is leaning towards theory #5.
