91.  This derivation is based on the bare fact that archaeologists have discovered numerous sites in the Kaliko Islands where the bones of fish were discarded, supporting the suggestion made by previous archaeologist that early humans generally relied on both fishing and hunting for food Plausible as the argument appears to be at first glance, close scrutiny of the fact, however, reveals that it lends little credible support for the arguer's assertion.

92.  Bones of fish were found at many different sites in the Kaliko Islands.

93.  In accordance with previous archaeological findings that there were numerous sites in Kaliko Islands where the bones of fish were discovered, suggestion about early humans generally relied on both fishing and hunting for food was put forward by archaeologists.

94.  It is where that worth to be questioned in that there are also many other factors contributing to various sites buried fish bones.

95.  For another, those sites can be originally rivers.

96.  With the discovery of numerous sites where the bones of fish were discarded, we can only draw the conclusion that those previous humans in the Kaliko Island relied on fishing, but not mammals.

97.  What we can find today are numerous sites where fish bones were discarded and stone knives which could be used for hunting.

98.  Since no finding of special sites where large mammals' bones were buried and no trace of slaughtering mammals, the conclusion of excessive hunting is not supportive.

99.  In addition, to prove that humans' extensive hunting is the main cause, the writer provides the evidence that fish bones have been discovered in numerous sites which shows a high possibility of mammal hunting.

100.  First, although archaeologists have discovered numerous sites in the Kaliko Islans where the bones of fish were discarded, we can not conclude that humans also hunted the mammals because we cannot find the bones of mammals which were discarded.
