Two cool science-y stories caught my eye today, both of them indicating that humans were far smarter, far earlier than previously thought. And probably much smarter than we are now.
The Antikythera Mechanism was discovered around 1900 about 40 meters down off the coast of a Greek island. There's been speculation ever since as to what it actually did. It was clearly one of the earliest geared mechanisms in the world, but until very recently people could only guess at what it did. Apparently, it does about everything people thought it did and more. I'd heard of this before, but scientists have been actually able to recreate the full mechanism. Acc. to CNN, it could "add, multiply, divide and subtract. It was also able to align the number of lunar months with years and display where the sun and the moon were in the zodiac." It also predicted eclipses. It's especially interesting because the science of the thing is about 1,000 years too early, suggesting that the Greeks may have been even smarter than we thought.
Archaeologists also discovered a 70,000 giant carved python in Botswana. That, along with various indications of ritualistic tools and implements indicates that the earliest human rituals happened about 30,000 years before previously believed.
