I'm guessing just one in a hundred is that person. But maybe not impossible, after all, that'd it'd be someone like her. Did you see what she saw? From the article:

> Her most disturbing studies came in the mid-1970s, when she and her team of field workers began to record a series of savage attacks.

> The incidents grew into what Goodall called the four-year war, a period of brutality carried out by a band of male chimpanzees from a region known as the Kasakela Valley. The marauders beat and slashed to death all the males in a neighboring colony and subjugated the breeding females, essentially annihilating an entire community.
