Dr. Jane teaches you some of the incredible secrets she’s uncovered about the intelligence of the animal and plant kingdoms, from chimps to trees.
If you look at what's been done with captive chimps in the field of intelligence, we have a whole other window into the chimpanzee mind. So they can be taught the signs of American Sign Language that's used by deaf people-- ASL. And they can learn 400 or more of those signs. And they can communicate, to some extent, with each other-- although usually it's with their teacher. Some chimpanzees-- not all-- love to paint. And this is in captivity, of course. And those chimps who've learned sign language will tell you what they painted. There's a very famous chimpanzee in Japan called Ai. And Ai learned so many things that she accomplished on a computer. And one of them-- imagine that you have a split screen on this side. You have numbers which appear randomly from 0 to 9. And, on the other side, there are 0-9 blank squares. And so Ai's task was to memorize the position of the randomly appearing numbers and then replicate that on this side. At the moment she pressed the first one-- 0-- that screen disappeared. And I've watched Ai several times. It's completely amazing how she remembers. And she enjoyed doing this so much, as soon as Matsuzawa called to her, she wanted to come and do this task. And she'd press these buttons. And if she made a mistake, the computer would make a kind of eh noise. If she did it right, she would get a little reward. If she made too many mistakes, at the end, she would sit there and beg to do the test again, even without getting any rewards-- simply so as not to make mistakes. And then she had a son, Ayumu. So the plan was, Ayumu wasn't going to be taught by humans. And so is Ayumu is just with his mother in the experiment room. Now Ayumu has become the equivalent of an enfant savant. And people have come from all over the world to try and beat him. He's got a photographic memory. So when you see the screen with numbers randomly from 0 to 9, by the time I found where 2 is, he's already started on the other side. And he never gets it wrong. He's just got this unbelievable photographic memory. So, you know, all the time, we're learning more and more different things about chimpanzee intellect. [MUSIC PLAYING] When parrot owners began talking about their birds, very often knowing exactly what the words they were using meant, and using them in the right context, science pooh-poohed it. Because the parrot brain is structured differently and, therefore, the birds are not capable of the kind of intellectual performances that mammals are. Well, this myth was broken by scientists studying crows in Oxford University in England. And they were studying two Caledonian crows, who were given a very simple task-- a glass tube with, I think it was a peanut at the bottom-- maybe a raisin, I'm not sure-- and a piece of wire with a sort of hook on the end. And they very quickly learned to push this down an...
There is still a window of time. Nature can win if we give her a chance. In her first ever online class, Dr. Jane Goodall teaches how you can conserve the environment. She also shares her research on the behavioral patterns of chimpanzees and what they taught her about conservation. You'll learn how to act locally and protect the planet.
I'm increadibly gratefull for this masterclass, this wisdom and courage I got with learning from it. Ready to make this world a better place!! Thank you so much.
Incredible class. If new ones in this area are included, I am in, along with with people I have talked to about this. Thank you!
Jane is very inspirational! She let me see things in a new way.
I took this class as I have always loved animals. Jane is an inspiring individual that made me want to be a better person.
