 However Hiscock (2004) provides an ethnographic observation from Australia and points out that the processes of making lithic flake are actually more social dynamic and with lots of negotiation between lithic knappers, the common measure attributes, such as retouched scar, form of flake and optimal economic presumption, are all less related to the function of the end-product.Although there are several other ethnographic studies lead to similar conclusion, Hiscock reminds that these observations are not to overthrow the classification system now but to provide an alternative possibility to consider lithic study.Shott proposed that the settlement mobility and lithic technology are related based on ethnographic and archaeological studies.
