Résumé	Strontium isotope provenance analysis uses the ratios of strontium-87 to strontium-86 in human skeletal remains to determine geographic origin and track human mobility and migration. Developed by Jonathan Ericson in the 1980s, this method exploits the fact that strontium isotope ratios in the environment vary geographically based on underlying geology. When individuals consume food and water from a specific region, they incorporate that region's characteristic strontium isotope signature into their bones and teeth, creating a geochemical fingerprint of their residence.	Use-wear analysis (also called microwear or tool-use analysis) is a method that infers the function of stone tools from microscopic wear patterns on their cutting edges and surfaces. Pioneered by Lawrence Keeley in the 1970s-1980s, this technique examines damage patterns, polishes, and edge rounding produced as tools contact different materials during use. By analyzing these wear patterns, archaeologists can determine whether a tool was used to cut plant material, meat, bone, hide, or wood—revealing detailed information about task specialization and subsistence practices in prehistoric societies.
