I'm talking about as far back as the creation of Stonehenge. I'm writing a research paper on its creation and need something to support my claim that the ancient's were far more intelligent then people are today due to how we have so many mental shortcuts (the calculator, the computer, etc.) But i can't really find an article anywhere that supports this theory. If anyone knows where i can find the article (or a link to the article), that would be great. Thank you in advance!!!!
