Having your photograph appear on the cove of a magazine makes you famous aroun the world. But imagine if that photo showed you hugging and playing with wild chimpanzees!
That's exactly what happened to Jane Goodall who shot to fame in 1955 when she appeared on the cover of National Geographic magazine. Jane inroduced the world to the social and emotional lives of the wild chimpanzees of Gombe, in eastern Tanzania.
Jane spent years living among families of wild chimpanzees. Her observations changed the way we view our closest animal relatives- and made us think about what it means to be human.
In this programme, we'll be hearing from the iconic environmentalist Jane Goodall. She reflects on how attitudes have changed as science has uncovered the deep connections between humans and the great apes- large primates including chimpanzees, gorillas and orang-utans, who are closely related to humans.
And of course we'll be learning some related vocabulary along the way.
As well as Dr. Goodall, the National Geographic photographs also made the chimpanzees of Gombe famous. People around the world became interested in the lives of a family of chimps living in a remote corner of Africa.
When Gombe's alpha female died in 1972, she was so well-loved that she had an obituary in The Times newspaper. But what was her name?
That's our quiz question:  which chimpanzee's obituary appeared in The Times? Was it:
a) Frodo?, b) Flo?, or c) Freud?
Well, 1972 is a bit before my time, Rob- I wasn't even born then, but I think it's  b) Flo.
Ok, Sam, we'll find out later if you were right. Now, when Jane first visited Tanzania in the 1960s most scientists belived the only animals capable of making and using tools were humans. But what Jane witnessed about the behaviour of one chimpanzee, who she named Greybeard, turned this idea on its head. Here she recalls that famous day to Jim Al khalili, for the podcast of BBC Radio 4's Discovery programme, The Life Scientific:
I could see this black hand picking grass sterms and pushing them down into the termite mound and pulling them out with termites clinging on with their jaws. And the following day, I saw him pick a leafy twig and strip the leaves, so not only was he using objects as tools but modifying those objects to make tools.
Jane observed the chimpanzee, Greybeard, finding small wooden branches called twigs and modifying them- changing them slightly in order to improve them.
By stripping away the leaves from twigs and using them to collect ants and termites to eat. Greybeard had made a tool - an instruments or simple piece of equipment, for example a knife or hammer, that you hold in your hands and us for a particular job.
Previously, it was believed that animals were incapable of making tools on their own. What Jane saw was proof of the intelligence of wild animals. Jane Goodall's studies convinced her that chimps experience the same range of emotions as humans, as she explains here to BBC Radio 4's The Life Scientific:
I wasn't surprised that chimps had these emotions. It was fascinationg to realise how many of their gestures are like ours...so you can watch them without knowing anything about them and when they greet with a kiss and embrace, they pat one another in reassurace, they hold hands, they seek physical contact to alleviate nervousness or stress- you know, it's so like us.
Holding hands, embracing and kissing were some of the chimpanzee's gestures- movements made with hands, arms or head, to express ideas and feelings.
In the same way as humans, the chimpanzees would pat each other- touch someone gently and repeatedly with their hand held flat.
Much of their behaviour was human-like. Just as I would hug a friend to reassure them, the chimps used physical contact to alleviate stress- make pain or problems less intense or severe. In fact, chmps are so alike jus that sometimes they even get their name in the newpaper!
