CHIMPS
SHAKE HANDS AND SOME CHIMP GROUPS ARE VEGETARIAN
In direct
parallel with human societies chimpanzees are showing cultural behaviours
that vary throughout the world.
Like humans
they greet each other with actions ranging from various handshakes
to arm raising. Like comparing the American handshake to the Japanese
bow, these amazing new studies show that chimps have multi-cultures,
which geographically display social differences. In the Congo, groups
of chimps, separated by the huge expanse of the Congo river display
very diferent social behaviours. On one side of the river groups
of chimps are carnivores and show aggressive behavior, whilst on
the opposite bank, the chimps are passive, thoughtful vegetarians
Apes
have the brains to talk.
Speech related
areas of the brain previously thought unique to humans have been
found in 3 members of the ape family.
Two researchers
in Atlanta, Georgia, US, carried out harmless MRI scans on chimpanzees,
bonobos and gorillas and discovered the same speech areas as in
human brains. Ape communicative behaviour stems from this same brain
area as human speech. It's thought that humans continued to develop
language whilst apes seemed happy to communicate with each other
by the occasional grunt and arm gesture. Oddly enough, an action
commonly used in many human households worldwide!
