Final answer:
Research specific to Sig and Falley regarding baboon possessions was not provided, but studies by other researchers like Michelle Brown help us understand baboon behavior and environmental interactions.
Step-by-step explanation:
The research of Sig and Falley is not mentioned directly within the provided references, and thus their findings on baboon possessions cannot be confidently conveyed. However, to provide some context, researchers such as Michelle Brown have been observing primates like baboons in natural habitats to understand their behavior in social structures, access to food, and other environmental adaptations. As part of a broader discussion on primate behavior and archaeology, it is also noteworthy to mention that studies on other primates, such as chimpanzees, have demonstrated their ability to utilize tools, and that this potentially relates to the broader concept of primates having possessions or interacting with their environment in significant ways.
