Today, a treat for mental_floss readers: The world premiere of a short film featuring Jane Goodall, chimpanzee expert and conservationist. Produced by Quoted Studios, this is an animated version of an interview from the public radio show Science Friday with Ira Flatow, conducted on September 27, 2002.

In the interview, Goodall discusses her book The Ten Trusts, her field work in Gombe, how she went for her Ph.D. without a B.A., and her opinion on Bigfoot—among other things.

I had the pleasure of seeing Goodall speak more than 20 years ago, and she's a fantastic communicator—intelligent, warm, witty, and honest. This is a lovely way to spend your next six minutes. Enjoy:

Ira Flatow: Now, I know you do wonderful chimp calls.

Jane Goodall: Well I'm going to do the greeting. It's the kind of sound you'd hear if you went to Gombe and you climbed up onto the ridge in the morning and if you're lucky you hear the chimpanzee who's calling out saying, "Here I am. It's a wonderful day. Where are you?" Woohwoohwoohwhoooahahahah.

Ira Flatow: Wow. That's great.

Jane Goodall: Each one has his or her own individual voice so you know exactly who's calling.

Caller: I wanted to know if you believed that there were any undiscovered, large ape species.

Jane Goodall: You're talking about a yeti or Bigfoot or Sasquatch.

Ira Flatow: Is that what's he's talking about?

Jane Goodall: Yes, yes he is.

Caller: Pretty much.

Ira Flatow: I'm out of the loop. Go ahead.

Jane Goodall: Now you'll be amazed when I tell you that I'm sure that they exist. I've talked to so many Native Americans who have all described the same sounds, two who have seen them. There was a little tiny snippet in the newspaper just last week which says that British scientists have found what they believe to be a yeti hair and that the scientist in the Natural History Museum in London couldn't identify it as any known animal.

Ira Flatow: Did you always have this belief that they existed?

Jane Goodall: Well, I'm a romantic, so I always wanted them to exist.

Jane Goodall: Animals were my passion from even before I could speak apparently. Then when I was about 10, 11, I found the books about Tarzan of the Apes. Fell in love with Tarzan. He's got that wife Jane, so I was terribly jealous of her. That was when my dream started. When I grew up, I would go to Africa, live with animals and write books about them. That's how it all began.

Jane Goodall: I got the opportunity when a school friend invited me to go and stay on their farm in Kenya. I was 23 and I sort of said bye-bye to family, friends and country and off I went. That's when I heard about the late Louis Leakey and somebody said, "Jane if you're interested in animals, you must meet Louis." Louis realized that I was the sort of person he said he had been looking for for about ten years who didn't care about hairdressing and clothes and parties and boyfriends. I really wanted to be in the wild.

Jane Goodall: It took him a year. He searched for money and eventually found a wealthy American businessman that said, "Okay Louis here you are. Here's enough money for six months. We'll see how she does." The chimpanzees ran away as soon as they saw me. They had not seen a white ape before and I knew if that six months money ran out before I had seen something really exciting everyone would have ... I would have let Louis down.

Jane Goodall: Of course at that time we were defined as man the toolmaker. That was supposed to differentiate us more than anything else in the rest of the animal kingdom.

Ira Flatow: You discovered that chimps could make tools.

Jane Goodall: David Greybeard, bless his heart, I saw him crouched over a termite mound. The whole thing putting in the grass, picking the termites up, picking up a leafy twig and stripping off the leaves which is the beginning of tool making. I couldn't actually believe it. I had to see it about four times before I let Louis Leakey know and then I sent a telegram and he sent back his famous, “Ha ha now we must redefine man, redefine tool or accept chimpanzees as humans."

Jane Goodall: After a bit Louis said, "Jane you have to get a degree because otherwise you can't get your own money and I won't always be around to get money for you." But he said, "we don't have time to mess about with a BA so you'll have to go straight for a Ph.D." He managed to persuade Cambridge in England to accept me as a Ph.D. student. When I got there, it was actually a very unpleasant and hostile reception that I had. I shouldn't have named the chimps. It wasn't scientific. I didn't know. I knew nothing. And worst sin of all was that I was ascribing to them emotions like happiness, sadness and so forth.

Ira Flatow: They were just aghast at you?

Jane Goodall: Yeah they were.

Ira Flatow: Whippersnapper.

Jane Goodall: I was even accused of teaching the chimps how to fish for termites, which, I mean, that would have been such a brilliant coup. [laughter]

(Bonus audio, rolling under credits.)

Caller: Do you think a primatologist's gender influences how they conduct their work?

Jane Goodall: Well I think in many cases it actually does. Louis Leakey always thought women were better as observers. He felt that they were more patient. Certainly it's very often true that women tend to be a bit quieter and more prepared to sit there and let the animal tell you things.

Ira Flatow: Would you rather be remembered for discovering the tool making abilities of the chimps or for your work in the environment today?

Jane Goodall: I think I'd like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom not separated from it. When I do go back to Gombe it’s to be in that timeless world where it's soft and where life is entwined and you actually see the pattern of nature. I always feel this great spiritual power which I believe is around.

This is the second installment in a three-part series; for the first video, see Buckminster Fuller on The Geodesic Life. We'll have the final video next week, featuring Richard Feynman (!).

Watch a School of Humpback Whales 'Fish' Using Nets Made of Bubbles 

Just like humans, humpback whales catch many fish at once by using nets—but instead of being woven from fibers, their nets are made of bubbles.

Unique to humpbacks, the behavior known as bubble-net feeding was recently captured in a dramatic drone video that was created by GoPro and spotted by Smithsonian. The footage features a school of whales swimming off Maskelyne Island in British Columbia, Canada, in pursuit of food. The whales dive down, and a large circle of bubbles forms on the water's surface. Then, the marine mammals burst into the air, like circus animals jumping through a ring, and appear to swallow their meal.

The video offers a phenomenal aerial view of the feeding whales, but it only captures part of the underwater ritual. It begins with the group's leader, who locates schools of fish and krill and homes in on them. Then, it spirals to the water's surface while expelling air from its blowhole. This action creates the bubble ring, which works like a net to contain the prey.

Another whale emits a loud "trumpeting feeding call," which may stun and frighten the fish into forming tighter schools. Then, the rest of the whales herd the fish upwards and burst forth from the water, their mouths open wide to receive the fruits of their labor.

Big Questions
Why Do Dogs Love to Dig?
Original image

Dog owners with green thumbs beware: It's likely just a matter of time before Fido turns your azalea bed into a graveyard of forgotten chew toys. When dogs aren't digging up your prized garden, they can be found digging elsewhere in your yard, at the beach, and even between your couch cushions at home. But what exactly is behind your dog's drive to turn every soft surface he or she sees into an excavation site?

According to Dr. Emma Grigg, an animal behaviorist and co-author of The Science Behind a Happy Dog, this behavior is completely normal. "When people say 'why do dogs dig,' the first thing that always comes to mind is 'well, because they're dogs,'" she tells Mental Floss. The instinct first appeared in dogs' wolf ancestors, then it was amplified in certain breeds through artificial selection. That's why dogs that were bred to hunt rodents, like beagles and terriers, are especially compelled to dig in places where such animals might make their homes.

But this tendency isn't limited to just a few specific breeds. No matter their original roles, dogs of all breeds have been known to kick up some dirt on occasion. Beyond predatory urges, Dr. Grigg says there are two main reasons a dog may want to dig. The first is to cool off on a hot day. When stuck on an open lawn with little to no shade, unearthing a fresh layer of dirt untouched by the sun is a quick way to beat the heat.

The second reason is to stash away goodies. Imagine your dog gets bored with chewing his favorite bone but knows he wants to come back for it later. Instead of leaving it out in the open where anyone can snatch it up, he decides to bury it in a secret place where only he'll be able to find it. Whether or not he'll actually go back for it is a different story. "There's a disconnect with modern dogs: They know the burying part but they don't always know to dig it up," Dr. Grigg says.

Because digging is part of a dog's DNA, punishing your pet for doing so isn't super effective. But that doesn't mean you should stand idly by as your yard gets turned inside-out. When faced with this behavior in your own dog, one option is to redirect it. This can mean allowing him to dig in a designated corner of the yard while keeping other parts off-limits, or setting up a raised flowerbed or sandbox especially to satisfy that urge. "You can get him interested in the area by burying a couple bones or some interesting things in there for him to dig," Dr. Grigg says. "I like the idea of buried treasure."

If your dog's motive for digging is more destructive than practical, he may have an energy problem. Dogs require a certain amount of stimulation each day, and when their humans don't provide it for them they find their own ways to occupy themselves. Sometimes it's by chewing up shoes, toppling trash cans, or digging ditches the perfect size for twisting ankles. Fortunately, this is nothing more walks and playtime can't improve.
