Finally, the behavior’s geographic distribution must be identified and its practice must be logically explained by culture.

Unformatted text preview: In this case, tool use among the Suaq orangutans seems to be a cultural behavior based upon the three very different techniques for food acquisition seen in practice by neighboring groups of primates. Although these separate groups inhabit similar areas with access to similar resources, only one developed the ability to use tools for extracting food from Neesia tree holes. The neighboring group utilized a less effective method of brute force for seed consumption, and the third group was not even aware of the nutrition available in the Neesia. Therefore, culture can be the only explanation for the geographic variance in behaviors seen among Suaq orangutans....
