*"Dian Fossey was trained by Jane Goodall and spent years working with her with chimpanzees before she was allowed to go an work with gorillas."
Absolute nonsense.
Back in the 60s/70s, the people working with gorillas/chimpanzees/orangutans didn't have the first idea what they were doing. It was all very much amateur trial and error. And indeed that was Louis Leakey's idea, when he sent his young female protegés off to Africa and Indonesia. Dian Fossey certainly did not spend 'years' with Jane Goodall.
"I had the wonderful opportunity to meet with Jane Goodall and talk to her about her experiences and she showed me her half missing finger and a few other scars that were caused by her being around an agitated chimp at the wrong time. "
We are talking about gorillas here.*
You're right, sorry I had a bit of Fossey's biography wrong. I was always more interested in her research then her life story. But she did visit Jane prior to going to her own camp and talked with her throughout.
It actually took Fossey years to be able to approach the troops, and multiple times she was "displayed" at by males who didn't want her near. She also witnessed infanticide and fights between males.
That isn't to say gorillas aren't gentle. In general they are. But Harambe was a 17 year old 400 lb male who had never sired children and was just entering what's considered his prime.
Jambo was 25 and had had several babies with mates by that point, which may have colored his perception of human children.
I'm not a primatologist (although I really wanted to be one growing up and read everything by Jane Goodall and Dian Fossey I could get my hands on), but what I saw was a big gorilla with a new toy that he didn't want to give back.
It's like the difference between a teenage boy and a middle aged man.
"Jane Goodall and Fossey also speak of the way chimps and gorillas wage war against other tribes and murder their young as displays of dominance. They are not as gentle as you would like to believe."
Fossey is dead. And she certainly did not promulgate the idea that gorillas (which are not chimps) were violent. In fact, she preferred them to the humans in the area. Certainly if you look at the facts there are no incidents of humans on gorilla treks being killed by gorillas, whereas there are many incidents of humans on gorilla treks being killed by humans.
