Science fiction often depicts humans of the future as creatures with enlarged foreheads, symbolic of the belief that we are evolving into smarter human beings. Recent studies, however, indicate just the opposite. It appears that the average IQ has dropped 14 points over the last 100 years in people of western nations. One factor cited is that more intelligent women tend to have fewer children than less intelligent women.
I would argue that technology is also a contributing factor in the decrease in human intelligence. 200 years ago our drive to develop interchangeable parts for our increasingly complex weapons led to machines capable of producing parts, assembly line techniques, and mass production. Craftsmanship, and its associated skills and wisdom, was on the way out. Further development led to computers and automation. Thinking is no longer required for the production of goods... or survival.
We are going through a period of rapid evolution, but what's evolving isn't us - it's our technology. We are becoming fatter, stupider and less fit for survival, while our machines are becoming more "intelligent" and self reliant.
Is it possible we are evolving into more apelike creatures?
