TLDR
People living in Bianfu Cave focused on hunting fairly large animals. They often used available materials as they were, instead of spending much time making specialized tools.

1 Study Aim
The study examines how Denisovans, an ancient human population, lived and obtained food in southwestern China. It focuses on their hunting choices and how they made and used tools. The authors ask whether their behavior favored flexible use of available materials over intensive tool production. The study seeks to explain how these people hunted and used everyday materials to meet their needs.
2 Study Design
The research investigates archaeological evidence from Bianfu Cave. The provided material identifies evidence for prey selection, stone-tool production, and bone use, but it does not report sample sizes or detailed analytical procedures. The authors characterize the stone technology as expedient core reduction, meaning quickly removing useful pieces from a stone core, alongside tool production. They also examine the widespread use of unmodified bones, meaning bones used without deliberate shaping. The researchers studied cave remains to reconstruct hunting behavior and material use.
3 Findings
The authors report specialized hunting of medium- to large-bodied prey at Bianfu Cave. They describe a technological strategy combining expedient core reduction with tool production. The research also finds pervasive use of unmodified bones. Together, these patterns suggest an adaptive system organized around object affordance, meaning the useful possibilities offered by available materials. The findings indicate that Denisovan subsistence did not always require intensive manufacture of specialized tools. These people mainly hunted sizable animals and made practical use of materials already at hand.
