Rethinking the peopling of the Americas, and the best ways to get groundwater back

First up on the podcast, we discuss a finding that’s likely to reignite debate over how humans first spread through the Americas. In the late 1990s, a site in southern Chile called Monte Verde forced archaeologists to adjust their views of the peopling of South America because it dated to about 14,500 years before present, which challenged the prevailing idea of when human inhabitants appeared on the continent. Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss new results published in Science that suggest Monte Verde is nowhere near that old. See the paper and related commentary. Next on the show, we talk about groundwater, a vital source of water for both drinking and agriculture that’s often overused and depleted. Producer Meagan Cantwell talks with Scott Jasechko, a professor of water resources with the University of California, Santa Barbara’s Bren School of Environmental Science & Management, about the many different approaches to improving groundwater supplies and what has worked where, which he reviews in this week’s issue of Science.
