proves so much, including how shit humanity can be
I feel sick inside and deeply ashamed ….
Koko is female…I swear these things always get something wrong.
I’m pretty sure that it’s talking about Michael the gorilla signing about his own mother, he was from Cameroon and his mother, and I think most of his famly, were killed for bush meat when he was a baby. Koko taught him sign language and when they asked about his mother he signed that :(
Washoe was a chimp who was taught sign language.
One of Washoe’s caretakers was pregnant and missed work for many weeks after she miscarried. Roger Fouts recounts the following situation:
"People who should be there for her and aren’t are often given the cold shoulder—her way of informing them that she’s miffed at them. Washoe greeted Kat [the caretaker] in just this way when she finally returned to work with the chimps. Kat made her apologies to Washoe, then decided to tell her the truth, signing "MY BABY DIED." Washoe stared at her, then looked down. She finally peered into Kat’s eyes again and carefully signed "CRY", touching her cheek and drawing her finger down the path a tear would make on a human (Chimpanzees don’t shed tears). Kat later remarked that one sign told her more about Washoe and her mental capabilities than all her longer, grammatically perfect sentences." 
Washoe herself lost two children; one baby died shortly after birth of a heart defect, the other baby, Sequoyah, died of a staph infection at two months of age.
