Amy Morgan, age 13, of Orlando, Fla., for her question:

WHEN DID THE NEANDERTHAL MAN LIVE?

Neanderthal man was a prehistoric man who lived in parts of Europe, Asia and Africa. Scientists say he lived from about 35,000 to 100,000 years ago.

Moat scientists classify Neanderthal man as an early sub species of Homo sapiens, or wise man. The word Neanderthal comes from the Neander Gorge near Dusseldorf, Germany. The first Neanderthal fossil, the top of a skull, was found there in 1856. Since then, similar fossils shave been found in more than 40 other locations.

Scientists used to say the Neanderthal man was rather stooped.

But fossils show that he stood about five feet two inches tall and walked fully erect. He had heavy bones, slightly curved limbs, big brow ridges and powerful teeth. His brain was as large as that of modern man.

Neanderthal man was a successful hunter in the subarctic environments of Europe. He lived in simple, temporary shelters and sometimes also in caves.

The fossil remains show that at least some Neanderthal people buried their dead with great care.
