In the many years that Jane Goodall observed and studied chimpanzees, she revolutionised our understanding of our closest primate cousins.

It took Leakey two years to find funding, which gave Goodall time to study primate behavior and anatomy in London.

Her work was published in leading journals, and in 1965 she made the front cover of National Geographic, introducing the world to the emotional and social lives of the primates.

In the meantime, the zoo shared photos of the new cute fuzzy primates.

They say this is evidence humans may have got our taste for alcohol from common primate ancestors who relied on fermented fruit - a source of sugar and alcohol - for food.
