In mid-June, the world was saddened by the news that Koko the gorilla had passed away. She was born in 1971 in the San Francisco zoo, and became known worldwide for her extremely high intelligence and gentle disposition. Since the age of 1, Koko began learning how to communicate through sign language, and passed countless tests which measured both IQ and self-awareness. Koko became somewhat of a celebrity and known figures including Robin Williams, Fred Rogers, Betty White, among others were known to visit and interact with her. Koko was a gentle soul who behaved so much like a human that she even requested to have a pet kitten for companionship, and mourned its death. Koko was a wonder of nature and taught us that the unity between us and other species is so precious. Rest in peace Koko.
