  "account": "At the end of the last Ice Age, early humans roamed the Americas, hunting and gathering with spears in hand. Nearly 13,000 years later, archaeologists are studying these ancient spearheads to understand how America's first inhabitants learned to adapt to unfamiliar environments. The Tennessee River Valley's earliest settlers left behind stone projectile points, which reveal how they managed resources and navigated new landscapes. Jesse Tune, an anthropology professor, explained that these early humans, like us, had the same needs and faced similar challenges. However, they lived in a world dominated by now-extinct animals like mastodons, mammoths, and giant sloths. The researchers analyzed about 500 spear points from the region to glean insights into the lives of the Clovis and Cumberland people. The Clovis groups, thought to be among the earliest inhabitants, were more likely to resharpen spearheads, possibly to manage their limited resources. In contrast, the later Cumberland people, who inherited the knowledge of resource locations from their predecessors, sometimes discarded points that were still usable, indicating a greater understanding and comfort in their surroundings. This comparison highlights that humans today still face similar decisions as our Ice Age ancestors - deciding what to carry and how to manage resources in new environments.",
  "summary": "At the end of the last ice age, early humans crisscrossed the Americas following seasons, rivers and game, often with a trusty spear in hand. Nearly 13,000 years later, archaeologists are using those spearheads to study how America's first inhabitants understood risk.",
