Evolution of
mankind:
The Story of
Communication
I want to start off with a simple
question — when do you think
wireless communication was
invented?
Late 20th century?
19th century?
You are not even close.
It was actually invented more than
2,000 years ago, through... smoke
signals!
Not the kind of wireless communication, you were thinking of, I guess. But
well, that is the oldest form of communication.
Fast forward 1,200 years and meet
Sultan Nur-ed-din, who built pigeon
lofts and dovecotes in Cairo and
Damascus; people were now using
pigeons to carry messages from Egypt to
cities as far away as Baghdad, in
modern day Iraq. This pigeon messaging system was extremely helpful in both
WWI and WWII — by delivering vital
messages that helped to save the lives of
thousands of civilians and combatants
alike.
