The fall of the Maya civilization was bloody and worsened by a 200-year drought

During the fall of the Maya civilization over 1,000 years ago, kings were killed in public, captives were taken hostage, and in one notably violent event in the city of Aguateca, Maya fled their homes during a surprise assault, without time to even grab their belongings.

And for the first time, scientists have deduced just how severe this centuries-long drought may have been.

Among the glistening dunes of New Mexico’s White Sands National Monument, scientists have been taken aback by the discovery of footprints.

The footprints belong to the extinct giant ground sloth, measuring seven to eight feet tall when on its hind legs, and sporting razor-like claws — vastly different to the lazy looking sloths you’re familiar with today. 

But it’s what’s inside these sloth footprints that’s captivated researchers: human footprints. This suggests hunters were possibly following the ground sloth step-for-step, despite the animal’s ability to strike and kill. Read more…

Fossil find gives middle finger to previous understanding of human exodus from Africa

Even for a desert, the Nefud is nearly bone-dry. Only about an inch of water falls onto the red, sandy soil in northern Saudi Arabia over the course of a year.
But 85,000 years ago, hippos roamed the Nefud. 
At that time, heavy, monsoonal downpo…
