Skeletal remains of early humans indicate clearly that our ancestors had fewer dental problems than we have. So, most likely, the diet of early humans was very different from ours.

Summarize Argument: Phenomenon-Hypothesis
The author concludes early humans had different diets than us. Her evidence is that skeletal remains of early humans show fewer dental problems than we have.

Notable Assumptions
The author assumes that virtually the only thing that could’ve caused fewer dental problems in early humans is different diets.

A
A healthy diet leads to healthy teeth.
We have no idea if early humans or modern humans have “healthy diets.”
B
Skeletal remains indicate that some early humans had a significant number of cavities.
Regardless, early humans had less dental problems than we do now.
C
The diet of early humans was at least as varied as is our diet.
We don’t care how varied their diet was. We need to strengthen the connection between early humans eating a different diet than ours, and early humans having less dental problems than us.
D
Early humans had a shorter average life span than we do, and the most serious dental problems now tend to develop late in life.
This weakens the author’s argument. Early humans had fewer dental problems because they didn’t live long enough to develop such problems, rather than because of their diets.
E
Diet is by far the most significant factor contributing to dental health.
In all likelihood, early humans had better dental health because of their diets. This affirms the author’s assumption that fewer health problems are a sign of better diets.
