Answer:

Correct Answer: B

Solution:

Cro-Magnon man emerged about 34000 years ago.

Thus it is regarded as most recent ancestor of today’s man.

It has, therefore, been called as Homo sapiens fossilis.

The Cro-Magnon man was like us, about 1.8 meters, tall well-built body.

Its face was perfectly orthognathous with an narrow, elevated nose, broad and arched forehead, moderate brow-ridges, strong jaws with man-like dentition and a well developed chin.

Its cranial capacity was, however somewhat more than ours, being about 1650 cc(ours is 1400 cc).

The Cro-Magnon man the direct ancestor of the living man.
