3. Along the history the humans create or perfectionate
tools.
Nowdays we have some examples of more complex tools such
as the hammer. In this presentation I will talk to you about this
evolution during the Prehistory.
4. One of the main innovations of the Palaeolithic period was the
“stonecutting” which consists on striking two stones for sharpening
one of the stones. One of materials they used was the silex.
Between about 400,000 and 200,000 years ago, the rhythm of
innovation in stone technology began to accelerate very slightly.
5. In the Upper Paleolithic. Tools are very diverse and
reflect stronger cultural diversity than in earlier times. Groups
of Homo Sapiens experimented with diverse raw materials
(bone and stone), the level of craftsman increased, and
different groups sought their own distinct cultural identity and
adopted their own ways of making tools.
6. In the Neolithic or new
Stone Age, people began to
live in settlements.
They had time to make tools
such as scythes and polished
axes.

7. Between the Stone Age and the Iron Age, the
discovery of how to make bronze from copper and
tin revolutionized tool and weapon-making.
Metal permitted longer, more resilient blades, so
the bronze sword evolved from the stone dagger.
They were also very effective when applied in the
head of an enemy
Bronze's composition of 90 percent copper and 10
percent tin was really strong and could be
polished into a golden sheen.

other Bronze Age tools.
