Archaeologists excavating a Neanderthal campsite found discarded gazelle teeth there whose coloration indicated that gazelles had been hunted throughout the year. The archaeologists concluded that the Neanderthals had inhabited the campsite year-round and thus were not nomadic. In contrast, the archaeologists cite a neighboring campsite of nomadic Cro-Magnons that contained teeth from gazelles all killed during the same season.
Which one of the following, if true, most seriously weakens the archaeologists’ reasoning?The archaeologists assume that the gazelle teeth found at the campsite were discarded there soon after the gazelles were hunted.
The key weakness is that the teeth may have been collected elsewhere or over time and then discarded at the campsite later. If so, year-round gazelle teeth do not prove
year-round habitation.
(A) Neanderthals hunted a wide variety of both migratory and nonmigratory animals.
Wrong. This does not explain why gazelle teeth from all seasons were found at the campsite.
(B) Cro-Magnons and Neanderthals sometimes exchanged tools.
Wrong. Tool exchange does not affect whether the gazelle teeth prove year-round habitation.
(C) Neanderthals saved gazelle teeth for use in religious rituals and later discarded them.
Correct. If Neanderthals saved the teeth and discarded them later, then the campsite could contain teeth from gazelles killed in different seasons even if the Neanderthals did not live there year-round.
(D) Cro-Magnons usually followed the migrations of the animals they hunted.
Wrong. This supports the idea that Cro-Magnons were nomadic, but it does not weaken the conclusion about Neanderthals.
(E) Gazelles inhabited the area around the campsites year-round.
Wrong. This may explain how gazelles could be hunted there year-round, but it does not weaken the claim that Neanderthals stayed there year-round.
Answer: (C)
