After 46 years of learning, making new friends, and challenging ideas about language, Koko the gorilla died in her sleep at her home at the Gorilla Foundation in Woodside, California on June 21, 2018. Koko first gained recognition in the late 1970s for her ability to use sign language, but it was her friendly personality that made her a beloved icon. Here are five facts you should know about the history-making ape.

1. SHE KNEW OVER 1000 SIGNS.

Francine "Penny" Patterson, then a graduate student at Stanford University, was looking for an animal subject for her inter-species animal communication experiment in the early 1970s when she found a baby gorilla at the San Francisco Zoo. Originally named Hanabiko (Japanese for "fireworks child," a reference to her Fourth of July birthdate), Koko took to signing quickly. Some of the first words Koko learned in "Gorilla Sign Language," Patterson's modified version of American Sign Language, were "food," "drink," and "more." She followed a similar trajectory as a human toddler, learning the bulk of her words between ages 2.5 and 4.5. Eventually Koko would come to know over 1000 signs and understand about 2000 words spoken to her in English. Though she never got a grasp on grammar or syntax, she was able to express complex ideas, like sadness when watching a sad movie and her desire to have a baby.

2. SHE CHANGED WHAT WE KNEW ABOUT LANGUAGE.

Not only did Koko use language to communicate—she also used it in a way that was once only thought possible in humans. Her caretakers have reported her signing about objects that weren't in the room, recalling memories, and even commenting on language itself. Her vocabulary was on par with that of a 3-year-old child.

3. SHE WASN'T THE ONLY APE WHO SIGNED.

Koko was the most famous great ape who knew sign language, but she wasn't alone. Michael, a male gorilla who lived with Koko at the Gorilla Foundation from 1976 until his death in 2000, learned over 500 signs with help from Koko and Patterson. He was even able to express the memory of his mother being killed by poachers when he was a baby. Other non-human primates have also shown they're capable of learning sign language, like Washoe the chimpanzee and Chantek the orangutan.

4. SHE HAD FAMOUS FRIENDS.

Koko received many visitors during her lifetime, including some celebrities. When Robin Williams came to her home in Woodside, California in 2001, the two bonded right away, with Williams tickling the gorilla and Koko trying on his glasses. But perhaps her most famous celebrity encounter came when Mr. Rogers paid her a visit in 1999. She immediately recognized him as the star of one of her favorite shows, Mister Rogers' Neighborhood, and greeted him by helping him take off his shoes like he did at the start of every episode.

5. SHE WAS A LOVING CAT MOM.

Koko was never able to have offspring of her own, but she did adopt several cats. After asking for a kitten, she was allowed to pick one from a litter for her birthday in 1985. She named the gray-and-white cat "All Ball" and handled it gently as if it were her real baby, even trying to nurse it. She had recently received two new kittens for her 44th birthday named Ms. Gray and Ms. Black.

The Queen’s Guard May Have to Give Up Their Iconic Bearskin Hats

Can you tell that this is real bear fur?

The UK’s departure from the European Union (EU) has given its leaders the chance to negotiate new trade deals and maybe even ban the sale of certain products—like fur. It’s something animal rights activists have long been pushing for, and a recently publicized letter from UK environment secretary George Eustice suggests that the government will indeed investigate the possibility.

As The Independent reports, Eustice wrote to the chief executive of the British Fur Trade Association that “once the UK’s future trading relationship with the EU has been established, there will be an opportunity to consider further steps it could take in relation to fur sales.” It’s far from a definitive proclamation, but since Eustice has seemed open to banning fur in the past, the letter has been taken as a positive sign for the anti-fur movement.

If the UK does eventually prohibit the sale of fur, this could mean the end of the authentic bearskin hats worn by the Queen’s Guard, who are most often seen stationed outside Buckingham Palace. According to Londonist, the 18-inch hats are created with fur from black bears killed during Canada’s annual black bear cull—a large-scale hunt that helps keep the population under control—and the UK Ministry of Defence purchases up to 100 new hats for the famously unflappable infantrymen each year.

The tradition of donning such eccentric headgear dates back to the Battle of Waterloo in 1815, when Napoleon’s Imperial Guard wore similar hats to make them seem taller and more intimidating. After the French were defeated by the Duke of Wellington and his British army, Britain adopted the hats as a symbol of victory.

But even if the UK does prohibit fur in the future, the Queen’s Guard could still keep the custom going. After all, there are plenty of convincing kinds of fake fur on the market these days. And as for what Queen Elizabeth II might think about the shift, we’re guessing she’d condone it; she herself gave up wearing fur products in 2019.
