Strange that nobody out of nearly 1000 anthropologists responds to the suggestion to discuss nest building behaviour of the Great Apes (Anthropology of Habitat an Architecture). It really seems to be a white surface on the "study-map" of anthropology. Unbelievable!
One individual (Chimpanzee, Bonobo, Gorilla or Orangutan) during about 45 years of practice builds a virtual tower of about 11 times the Eiffeltower in Japan. NO INTEREST!
There are also interesting type differences: a) tree nests in arboreal space! And b) ground nests in the terrestric space. Highly important difference! BUT NO INTEREST!
In addition: mothers teach their children for about four years until they are capable to build their own nest within 2 to 3 minutes. Learning is involved! NO INTEREST!
In addition the nest building behavior represents an important spatial and social principle of order: The chief has the key for the "apartment". The female with her baby sits in a tree nest in the centre, protected by the others in the outer line: my home is my castle. NO INTEREST IN ALL THAT! Signed "Anthropologists"!
Maybe there is something wrong in primatology and anthropology!
