Some people think that the main differences between humans other animal species is our ability of complex reasoning, our use of complex language, our ability to solve difficult problems, and introspection (this means describing your own thoughts and feelings).

about 200,000 years
How old are modern day humans?
So far, the earliest finds of modern Homo sapiens skeletons come from Africa. They date to nearly 200,000 years ago on that continent. They appear in Southwest Asia around 100,000 years ago and elsewhere in the Old World by 000 years ago.

Are humans brains getting smaller?
I don’t mean to alarm you, but the average human brain size is shrinking. It’s something of a well-known secret among anthropologists: Based on measurements of skulls, the average brain volume of Homo sapiens has reportedly decreased by roughly 10 percent in the past 40,000 years.
Why do humans have large brains?
Brain size increased rapidly during human evolution due to the expansion of many brain regions, resulting in human brains being exceptionally larger than those of our closest relatives. Humans have much larger brains than other primates, but it is not clear exactly when and how this difference emerged during evolution.
What characteristics set humans apart from animals?
Like many a scholar before and since, Bertrand Russell confidently asserts that certain traits—“speech, fire, agriculture, writing, tools, and large-scale cooperation”—set humans apart from animals. Although we appear to excel in many domains, such claims are not typically founded in any thorough comparison.
Are our brains evolving?
As early humans faced new environmental challenges and evolved bigger bodies, they evolved larger and more complex brains. Over the course of human evolution, brain size tripled. The modern human brain is the largest and most complex of any living primate.
