Curious about ways in which homo sapiens may conceive of intelligence newly in orangutans and in comparison with humans, in English (and other languages)...
What are the greatest writings about this?
Orangutan wiki subject at World University and School ...
In what ways would http://worlduniversity.wikia.com/wiki/Environmental_Studies and even http://worlduniversity.wikia.com/wiki/Environmental_Engineering help increase Orangutan populations significantly?
Here are some examples from Wikipedia:
Orangutans are among the most intelligent primates; they use a variety of sophisticated tools and construct elaborate sleeping nests each night from branches and foliage. The apes have been extensively studied for their learning abilities. There may even be distinctive cultures within populations. Field studies of the apes were pioneered by primatologist Birutė Galdikas.
And see in the "Orangutan" Wikipedia article too:
Dr Birutė Galdikas looks a bit like she's "gone native" here (in an anthropological sense, too) in presenting a book ...
