Genes, rather than fossils, can help us chart the migrations, movements and evolution of our own species—and those we descended from or interbred with over the ages. The oldest-recovered DNA of an early human relative comes from Sima de los Huesos, the “Pit of Bones.” At the bottom of a cave in Spain’s Atapuerca Mountains scientists found thousands...
As the physical remains of actual ancient people, fossils tell us most about what they were like in life. But bones or teeth are still subject to a significant amount of interpretation. While human remains can survive after hundreds of thousands of years, scientists can’t always make sense of the wide range of morphological features they see to def...
Our ancestors used stone tools as long as 3.3 million years ago and by 1.75 million years ago they’d adopted the Acheulean culture, a suite of chunky handaxes and other cutting implements that remained in vogue for nearly 1.5 million years. As recently as 400,000 years ago, thrusting spearsused during the hunt of large prey in what is now Germany w...

But it appears that we had a tendency to wander from a much earlier era than scientists had previously suspected. A jawbone found inside a collapsed caveon the slopes of Mount Carmel, Israel, reveals that modern humans dwelt there, al...
