That episode of Nature featuring Snowflake the white gorilla that we told you about finally reran this weekend. It was so good. Try to watch this clip and not crave a baby gorilla as a pet. Snowflake had such an interesting life, since he was born right around the time that serious studies on the intelligence of primates was kicking off. Snowflake's coloring—a genetic disorder akin to being albino—saved his life (he wasn't killed by hunters in Africa, because they recognized the rarity of a white gorilla). But it's also the same thing that killed him: Being so light made him vulnerable to the sun, and he died at the age of 40 from skin cancer. Clip above.
