Key changes observed during the Upper Paleolithic (from about 40,000 to 10,000 years ago) include all of the following except

A) increased sophistication of tools.
B) expansion of the human geographic range.
C) domestication of most plant and animal foods.
D) the invention of new equipment, such as bows and arrows.
All of the above occurred between 40,000 and 10,000 years ago.

Answer 1

A) increased sophistication of tools.

Step-by-step explanation:

Technological advances have included significant developments in the production of flint tools, including fine-blade based industries instead of simpler and shorter shards. A sheath made of different materials and a stone tool for scraping and polishing made it possible to work on bones, antlers and skin. Advanced hunting spears and harpoons also appear during this period.
