after mastering agriculture and
livestock man gradually abandoned his
nomadic lifestyle in societies became
sedentary with the first permanent
settlements this cut with the nomadic
path became known as the Neolithic
Revolution some settlements kept
developing themselves and their
population began to grow in numbers this
new form of society began to divide
labour creating classes of experts in
certain activities and thus the division
of society in social classes was getting
clear trading with other settlements was
also more common some of these
settlements became trading posts which
boosted their growth and development
with the first cities now appearing
scholars claimed that the first cities
were born on the banks of the Tigris and
Euphrates rivers in Mesopotamia today’s
Iraq the cities of baroque and everdew
are considered to be the first cities
founded by men with that the first great
civilization today known as the
Sumerians was born the vast number of
products that were demanded by the
cities could turn into a logistical
bedlam but instead it stimulated the
mundane use of a new invention the wheel
it is likely that the invention of the
wheel derives from the observation of
trunks being rolled to move heavy cargo
the first wheels were massive and had
bumpy axles but those mechanisms were
perfected over the years the lubrication
of the axles and the invention of the
wheel with rims made them much more
efficient but the decisive factor was
the use of animal drag vehicles like
oxen donkeys and horses making wheels
even more popular
this new invention quickly
revolutionized the way man could
transport goods and people and the wheel
soon entered the battlefield chariots
were systematically used as combat
vehicle in ancient battles contrary to
popular belief the native people of the
Americas were already knowledgeable of
the wheel when the Europeans discovered
the new world however it was barely used
as Native Americans did not have access
to animals like the horse for instance
taking into consideration that
limitation these people opted for other
means that they considered more
efficient to transport their cargo the
impact of the wheels invention altered
many areas not only transportation the
wheel was also used in several other
mechanisms which would be crucial to the evolution of mankind
