Question

Improvements in tools during the Mesolithic Era include the use of bones.

Answer 1

The Stone Age, the Bronze Age, and the Iron Age are three period of history identified by the way people made tools and weapons. Different ancient civilizations developed at different speeds. So you might have one group of early people using bronze tools, while another group was still using stone tools.  Those with better tools had a much easier time conquering other groups of people. The material used to make tool and weapons most definitely had an influence on daily life in ancient times.
