an international team of scientists found evidence that orangutan groups differ in everything from bedtime rituals to eating habits to sexual practices - patterns of behavior, passed from generation to generation, that scientists call culture.
they live just like we do. say if you are Chinese, you eat using chopsticks and if you are Malay, you eat using your hands. while some people kiss as they greet each other, other people only shake hands, and the same concept is applied in Orang-Utans' culture. blimey, never thought they even have one!
*** in some particular place, Orang-Utans cheer before they go to sleep, but in other parts of the jungle, they dont.
*** And while in two forests, orangutans enjoyed masturbation using sticks, elsewhere such behavior was unheard of.
the researchers say it is probably because of the differences in their forest habitat and there is no evidence of genetic variation what-so-ever, so all of us can stop hoping that we might see the famous evolution takes place in our century.
In addition, at sites where orangutans spent more time together there were more of these widespread behaviors, as would be expected with behaviors that can be spread through association. so, the closer sites were to one another, the more behaviors those sites shared, again as would be expected. just like what you can see in some human tendency depending on the neighborhood they live in. examples, the difference between Lembah Keramat and Taman Melawati eh?
maybe these Orang-Utans even have a community chief or something?
