EARTH Magazine: The First Americans: How and When Were the Americas Populated?
From EARTH Magazine, January 4, 2017 -- The latest research suggests humans first arrived in the Americas as early as 16,000 years ago, but using which path — along the Pacific coast, through an inland ice-free corridor, or from the East along the Atlantic coast — remains controversial. Archaeologists and geologists are working to try to answer the question of how and when the first Americans arrived. In the January issue of EARTH Magazine, their work is showcased, reexamining the origins of our shared geoheritage in light of new evidence.
Listenwise: Climate Change and Human Migration
From Listenwise -- Migration has been a huge part of human history. Experts agree that early humans started out in Africa and began to migrate out of Africa to different parts of Europe and Asia around 100,000 years ago. This migration occurred in waves but we don’t know why early humans left Africa. Recent research supports the theory that climate change may have been the force that drove early humans out.
EARTH Magazine: Humans, Megafauna Coexisted in Patagonia before Extinction
From EARTH Magazine, October 12, 2016 -- As we celebrate National Fossil Day, EARTH Magazine brings you a story set in Pleistocene South America, where the climate was warming following an ice age. At this time, Patagonia was home to large megafauna species like giant sloths and saber-toothed cats. There was also a new predator on the block: humans. At some point as the climate warmed and human settlers began hunting, the megafauna living in Patagonia and Tierra del Fuego went extinct.

Listenwise: Oldest Human Fossil Could Be Missing Link in Human Evolution
From Listenwise -- The earliest known fossil that lead to humans was recently discovered in Ethiopia. Scientists have uncovered a lower jaw with five teeth. The jaw is estimated at about 2.8 million years old, and is nearly half a million years older than the previous record for a human-related fossil. This bone could help explain a branch in the human family tree. Listen to the story to find out how this fossil could fill a gap in the history of human evolution.
