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.
