There is evidence to suggest that our cave-dwelling ancestors polished many of their flints to a degree far surpassing what was necessary for hunting purposes. It seems, therefore, that early humans possessed an aesthetic sense.

Summarize Argument: Phenomenon-Hypothesis
The author hypothesizes that early humans could appreciate aesthetics. This is shown by the phenomenon that early humans often polished stones more than was needed for hunting purposes.

Notable Assumptions
The author assumes that the only reason early humans would polish flints beyond what was necessary for hunting is to appreciate the aesthetics of the highly polished stones. The author further assumes that there are no other explanations for this degree of polishing.

A
Most flints used by our cave-dwelling ancestors were not highly polished.
This does not affect the argument. The premise states that “many” of the early humans’ flints were highly polished; most of them not being highly polished is compatible with the argument.
B
The caves in which the highly polished flints were found are unadorned by cave paintings.
This does not affect the argument. A lack of cave paintings does not undermine the idea that early humans possessed an aesthetic sense—perhaps they appreciated the aesthetics of highly polished flints but did not care for the aesthetics of cave paintings.
C
There is evidence that these highly polished flints were used for display in religious ceremonies.
This strengthens the argument. If the purpose of the highly polished flints was for display in religious ceremonies, early humans must have had an aesthetic sense that motivated them to polish the flints for this purpose.
D
Flints were often used by early humans for everyday chores other than hunting.
This weakens the argument by offering an alternative explanation for the described phenomenon. The highly polished flints—while not necessary for hunting—could have been used in everyday chores. This explanation gives no reason to suggest that early humans had an aesthetic sense.
E
Any benefits that an aesthetic sense would have given to cave-dwelling humans are poorly understood.
This does not affect the argument. Our poor understanding of the benefits early humans could have derived from an aesthetic sense does not undermine the assertion that they may nevertheless have possessed an aesthetic sense.
