Do modern Homo sapiens share the same baseline intelligence levels as early Homo sapiens? i.e. could a newborn human from 200,000 years ago be raised in our society without any cognitive disadvantages?

If not, is there an idea of how much brain evolution has occurred since Homo sapiens first appeared? Are we smarter than humans from 100,000 years ago or even 10,000 years ago?

It has been hypothesised that humans 10,000 years ago were *possibly* more intelligent than humans now.

The selective pressure 10,000 years ago favoured more intelligence due to requiring creativity regarding survival and avoiding murder.

Since the creation of dense city-states, selective pressures would likely have led to a bias toward those who were more likely to survive contagious disease; this does not require intelligence (Though the ability to innovate sanitation certainly helps.)  

If you're talking about 100,000 years ago you have to note that there two main species of humans at that point but the best evidence that there were humans with similar minds to ours are examples of paleolithic art that go back as far as 40,000 years. 

Why there are not examples of paleolithic art before that is debatable and probably unprovable.
