The trait of head size has become generally fixed in modern human beings. [112] While decreased brain size has strong correlation with lower intelligence in humans, some modern humans have brain sizes as small as with Homo erectus but normal intelligence (based on IQ tests) for modern humans. Increased brain size in humans may allow for greater ...

As the tests became more popular, belief that IQ tests measure a fundamental and unchanging attribute that all humans possess became widespread.

[5] Additional to the functions of linear logic and the patterns of formal logic the intellect also processes the non-linear functions of fuzzy logic and dialectical logic.
In adult humans, thicker cerebral cortex has been linked to higher intelligence. [67] The neocortex is the most advanced and most evolutionarily young part of the human brain. It is six layers thick and is only present in mammals. It is especially prominent in humans and is the location of most higher level functioning and cognitive ability. [68]
While speed increases seem to be only a quantitative difference from human intelligence, actual algorithm improvements would be qualitatively different. Eliezer Yudkowsky compares it to the changes that human intelligence brought: humans changed the world thousands of times more rapidly than evolution had done, and in totally different ways ...
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...

This view of human history was more compatible with an evolutionary origin ...
