The evaluation of man has been the subject of intensive
investigation for centuries since Darwin has provided the
foundation with his theories.
Using tools has been interpreted as a sign of intelligence,
and it has been theorized that tool use may have stimulated
certain aspects of human evolution-most notably the
continued expansion of the human brain.
The use of stones is believed to be the first ever used tool as
the simple tool for hammering, which became a steppingstone
towards evolution of more and more tools of its kind.
This tool-making tradition lasted virtually unchanged for a
million years. Tools were made by breaking an angular rock
with a “hammer stone” to give simple, sharp-edged stone
flakes for chopping and slicing.
Making sparks while hammering stone is common. This tool
lead to fire making. Humans were no longer dependent on
nature sources of fire and that ignited the desire to evolve.
This tool also led to invent wheel, the most crucial invention
of mankind responsible for today’s modern technological
The way humans make and use tools is perhaps what sets
our species apart more than anything else. Now scientists
are more and more uncovering the forces that drove our
lineage to our heights of tool use — and how tool use, in
turn, might have influenced our evolution.
