If humans have remained unchanged for millions of years, howcome our technological abilites have surged over the past several thousand years? And not earlier
Well, human beings, similiar to us have only really been around for the last,
200,000 years. There have been some pretty catastrophic changes to the earth's climate in between, like
Ice Ages. About
30 to 40,000 years ago there were still at least
two distinct human types,
Homo Sapiens and
Homo Neanderthalis.
Homo Sapiens as we know them today spent a long and probably very satisfying time as
Hunter/Gatherers before experimenting with
Nomadic Animal Husbandry,
Farming, the development of
Trading Settlements and
Towns.
It was in the more arid parts of the world that technologically advanced,
Irrigation Cultures developed to make the most efficient possible use of the available water supply. This was so successful, that these cultures endured somtimes hundreds, or thousands of years with little real change. Rising and falling, dependant, mostly, on the upkeep of vast, centralised, systems of irrigation and distribution.
As the technologies, like metal working moved out from the arid regions into more temperate and congenial parts there was a population explosion which forced an
Agrarian Revolution especially in the Mediterranean region. There was a subsequent trading and population explosion and the growth of
Empire Building cultures, which rose and fell over thousands of years.
Sumeria, Babylonia, Phoenecia, Carthaginia, Troy, Athens, Sparta, Rome, Byzantium, Holy Roman Empire, Ottoman Empire, British Empire, etc. And that's only in the Western Hemisphere and Middle East! Helped keep our ancestors busy and no mistake!
