Fact: All Mongols evolved from the sponge. (disclaimer: this is not a fact.)

[Maya S.]

Sponges, the biological exception as in the case of the Mongols. I love crash course.

[French Dork]

At first I mistook taxonomy for taxidermy and got really confused.

[cookiemonkey777]

yup. In terms of biology hair and fur are the same.

[mrwhite1323]

Question: Humans are also classified in the class Mamalia, so does our arm / leg hair count as "fur"? Or is fur not a requirement for the Mamalia class?

[Krieg Jaeger]

Linnaeus was born before Charles Darwin and Darwin's discovery of evolution. That means Linnaeus used evolutionary traits to classify things before evolution was known.
