wait but why: Putting Time In Perspective Humans are good at a lot of things, but putting time in perspective is not one of them. It’s not our fault—the spans of time in human history, and even more so in natural history, are so vast compared to the span of our life and recent history that it’s almost impossible to get a handle on it. If the Earth formed at midnight and the present moment is the next midnight, 24 hours later, modern humans have been around since 11:59:59pm—1 second. And if human history itself spans 24 hours from one midnight to the next, 14 minutes represents the time since Christ. To try to grasp some perspective, I mapped out the history of time as a series of growing timelines—each timeline contains all the previous timelines (colors will help you see which timelines are which). A note on dates: When it comes to the far-back past, most of the dates we know are the subject of ongoing debate. For teachers and parents and people who hate cursing: here’s a clean, Rated G version.

Medically Accurate 3D Human Anatomy Models Science Shows Prehistoric Gender Equality: Cave Women Rocked You know the cartoon where a caveman clubs a cavewoman over the head, then drags her to his lair by her hair? The blood-boiling message is that male dominance is natural and immutable, rooted deeply in our genes and behavior. Screw that. Scientists are finding that in prehistoric societies, females may have been equal to males in many ways. 1. Take the assumption that men painted and drew the images we can still see in their caves. It turns out that women made their mark too — they may even have been responsible for the majority of those pictures. 2. The stencils women made of their hands appear next to paintings of animals their societies hunted and ate. Some anthropologists argue that female Neanderthals participated in hunting, a dangerous activity, in part based on their skeletons’ displaying the same bone fractures as male skeletons do. 3. If everyone stayed in those little prehistoric cave clans and mated with the folks they knew, some scary inbreeding would result. 4.

Lee The temple of Angkor Wat, the Egyptian pyramids, Stonehenge, and the famous statues on Easter Island were all built without the conveniences of modern technology. Ancient peoples didn't have access to forklifts, hydraulic cranes, or flatbed trucks. So how did they build the temples and statues that we admire today? In some cases, all they needed was rope, a little manpower, and some ingenious carving. A new study published this week in the journal Proceedings of the National Academy of Sciences finds that ice roads lubricated with water enabled workers in 15th- and 16th-century China to slide stone blocks to Beijing in order to build palaces in the Forbidden City. Making nature work for them is a common theme in the techniques experts think ancient peoples used to build their monuments and temples. "We forget that ancient people are just as smart as we are," said Terry Hunt, an archaeologist at the University of Oregon who studies the Polynesian culture of Easter Island.
