Answer:
Correct Answer: B
Solution:
Cro-Magnon man emerged about 40000 years ago.
Thus it is regarded as the most recent ancestor of today’s man.
It has, therefore, been called Homo sapiens fossilis.
The Cro-Magnon man was like us, about 1.8 meters tall, with a 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 is the direct ancestor of the living man.
