Evolution affects humans too.

I present to you 5 facts.

1: Civilisation started after early homosapiens migrated from Africa into hostile ice age Europe.
2: Adaptions occur more frequently when an animal enters a new environment.
3: By far the most important adaption in recent human evolution is the brain. A neanderthal with a human brain would not be significantly worse or better off than a human.
4: Physical adaptions take longer to evolve than the simple increase in size of the neo-cortex.
5: Humans do have a plethora of physical adaptions to various environments.

Cranial capacities from wiki...
http://en.wikipedia.org/wiki/cranial_capacity

It could be argued that cro magnon had a larger cranial capacity as they had larger bodies, but they were only a few inches taller and their brain capacity was between 6-16% higher than modern humans. Also cro magnon has a reputation for having a large forehead which is where the neo-cortex and language centers are housed in the brain. As the brain grows the skull would expand more around this area compared to modern humans.

From various sources on google human brain capacities lie between 1300 and 1450, whilst cro magnon brain capacities lie between 1400 and 1730.
