Joke: Chimps

Chimps can match up the faces of group members with photos of their behinds. The
ability, researchers say, shows that chimps carry around mental representations with
"whole body" detail of chimps they have encountered.
Primatologists Frans de Waal and Jennifer Pokorny of the Yerkes National Primate
Research Centre at Emory University in Atlanta, Georgia, tested how well six adult
chimpanzees could link pictures of various chimpanzee behinds, either male or female,
with photos of individual chimp faces.
They showed a chimp, first, a photo of a chimp's behind, including genitals, then the faces
of two chimps, both of the same sex as that behind. Each of three male and three female
chimps were able to make the correct face-with-behind pairing with a probability
significantly higher than chance.
perhaps we might all upload photos of our butts onto E cards and send them out so that
we can recognize each other when we meet?
