Final answer:
Scientists determined Salam's age at time of death using a method called transition analysis, which estimates age from skeletal samples.
Step-by-step explanation:
Scientists determined Salam's age at time of death using a method called transition analysis, which estimates age from skeletal samples. This method looks at changes in certain parts of the skeleton that occur predictably with age. By analyzing the morphology of these skeletal features, scientists can assign an approximate age at death. This method has been used in paleodemography studies to estimate ages in adults and has provided valuable insights into historical mortality patterns.
