Recent research undertaken at NYC’s State University of New York Downstate Medical Center, and published in the journal Frontiers in Evolutionary Neuroscience, indicated that worrying may have evolved in conjunction with intelligence as a critical survival mechanism in human beings.

Scientists compared research subjects who had generalized anxiety disorder with subjects who did not have the disorder. They discovered that worry as well as high intelligence were connected with specific brain activity, measurable by changes in the brain’s white matter. The results suggest that anxiety (worry) may have evolved right alongside intelligence as an important means of survival.

In a medical center news release, Professor Jeremy Coplan said: "While excessive worry is generally seen as a negative trait and high intelligence as a positive one, worry may cause our species to avoid dangerous situations, regardless of how remote a possibility they may be… In essence, worry may make people ‘take no chances,’ and such people may have higher survival rates. Thus, like intelligence, worry may confer a benefit upon the species."
