Jane Goodall

Really until quite recently, there hasn't been that obvious a difference in the way they treat or they treated male and female researchers.

But we now have one chimpanzee who's a rogue and he's actually very dangerous to female researchers and most particularly to me.

And it's very sad, after 32 years in the field, that one chimpanzee has, in a way, made Gombe feel a little unsafe to me today.

What does he do that's a threat to you?

He's probably ten times stronger than I am.

I mean, a big male chimp is said to be four to five times stronger than an adult human male.

And Frodo is the largest, heaviest chimp we've ever known at Gombe.

He's 115 pounds.

He's about 20 years old.

He's absolutely magnificent.

He's one of Fifi's offspring.

And what he'll do is display that's charging with his hair bristling, dragging branches and things straight towards me, pull me over, stamp on me, perhaps display away, come back and do the same thing again.

He's actually done it three times.

I can only think that it's because of all the people working at Gombe.

He has the least fear of me.

I've always been able to get very close to even nervous individuals, and that's because I'm calm and quiet and I don't try to get too close and I don't push.

And so he has absolutely no fear, no respect, no...

nothing that will block his aggressive behavior towards humans, particularly me.

I doubt they think very much now.

I think we're just part of the environment.
