essay on tool use

A.    Primate tool use


 It is apparent that common chimps and some other non-human primates (NHP) use tools to a certain extent as evidenced in your readings and videos. Write a 1 to 2 page essay that discusses each of the following points, using examples.


a)   Describe 3 distinctly different situations –different functions – where chimps have been observed using tools in  nature.


b)   the means of acquisition of tool use in chimps – that is, how does it appear chimps become tool users ? This is not asking where do they get tools but how do they acquire the use of the tool – that is, become tool users.


c)    What are two specific adaptations that facilitate chimps tool use  (e.g why chimps but not dogs.....)


d)     Describe at least one important difference between chimp tool use and human tool use.


e)    significance of tool use

 Conclude this with a one or two concluding sentence statement on the significance -- as you see it -- of tool-use in understanding primate behavior in their natural habitats and in captivity or other human contexts.
