Chemical litter sit ominously at the bottom of the ocean. Is there destruction in the horizon? Scientists study the phenomenon.
It has long been thought that Easter Island's early Rapa Nui civilization collapsed due to lack of a lack of resources that eventually led to war. This theory was based on war-like weaponry scattered across the island. A new study, however, disproves the theory, stating the artifacts are nothing more than tools.

So what happened to the Neanderthals? That's been a question on a lot of experts' minds ever since it was first determined that the human-like sub-species vanished from the face of the Earth some 40,000 years ago.

Now, experts have found strong evidence that strongly disputes that claim.
