Extra ordinary high intelligence or conciousness level in humans as compared to animals
As per the Darwin's theory of evolution many species were evolved from the primitive life forms and a large number of animals came into existence on this planet Earth. The evolution was not a one day affair as it took millions of years in evolution of the species and that geological time scale is mind boggling and is beyond the comprehension of a normal person.Most of the scientists believe in Darwin's theory though there are some who have different opinions but there are facts and figures that make Darwin's theory the most acceptable one in this knowledge area.
During the long period of evolution there were climate changes on Earth cycling between high temperatures and ice ages laced with sea level changes. But all that happened very slowly and still happening but we humans cannot take cognizance of that as our observation period is very small limited to a window of say 100 years on the long time line of about approximately 3.7 billion years since basic life form is said to be evolved on Earth.
Humans as evolved from apes are said to come in existence about roughly 2 million years back and they can be termed as primitive humans while beginning of modern humans is being deduced somewhere around only the 200000 years back.
Understanding of these figures on the geological time scale helps in understanding the evolutionary processes for all the animals especially in respect of the humans who have surprisingly a highly developed conciousness level as compared to all other animals evolved or present today.
What could be the reason of this extra ordinarily high intelligence or conciousness level in humans? Any ideas?
