Asked by daniel
A primate species with a brain size of 1200 cc is discovered.
A graph entitled Change in hominid cranial capacity over time has time in million years ago on the horizontal axis, and brain size in cubic centimeters on the vertical axis. Brain size steadily increased, and then rapidly increased recently.
From the information in the graph, what can be predicted about this species?
The species is closely related to modern humans.
The species was smarter than modern humans.
The species lived between 1.5 and 1 million years ago.
The species lived between 1 and 0.5 million years ago.

The species lived between 1 and 0.5 million years ago.
Reason: On the graph the curve reaches about 1200 cc during the interval from 1.0 to 0.5 million years ago. You cannot conclude it was smarter than modern humans (brain size alone isn’t a direct measure of intelligence) or definitively that it was closely related to modern humans from cranial capacity alone.
