Some scientists believe that small humanoid skeletons found on an Indonesian island are the remains of human beings with a growth disorder. It is more likely that they represent a distinct human species that became smaller over time due to environmental pressure. These skeletons do not fit the pattern of known growth disorders. And evidence suggests that certain fox and mouse species on the island have evolved into smaller versions of their common counterparts.

Summarize Argument: Counter-Position
The author concludes that the humanoid skeletons are a distinct species of human that developed from environmental pressures, rather than humans with growth disorders. As evidence, she cites a generalization about growth disorders and other species on the island that also evolved into smaller versions.

Identify Conclusion
The conclusion offers an alternate explanation about the skeletons found on an Indonesian island: “It is more likely that they represent a distinct human species that became smaller over time due to environmental pressure.”

A
Some scientists believe that the humanoid skeletons are the remains of human beings with a growth disorder.
This is the position that the author is arguing against rather than their own conclusion.
B
It is more likely that the humanoid skeletons represent a distinct human species than that they are the remains of human beings with a growth disorder.
The author argues for this view using two pieces of evidence. Rather than humans with growth disorders, she posits that the humanoid skeletons represent a distinct species.
C
The humanoid skeletons do not fit the pattern of known growth disorders.
This is evidence for our conclusion. How do we know they’re not just humans with growth disorders, as some scientists believe? For one thing, they don’t align with what we know about growth disorders.
D
Certain fox and mouse species on an Indonesian island have evolved into smaller versions of their common counterparts.
This is evidence for our conclusion. If other species on the island evolved to become smaller, it seems possible humans did, as well.
E
Environmental pressure can cause species living on islands to become smaller over time.
This is a generalization drawn from the evidence about fox and mouse species.
