Costs Of Group Locomotion: How Infant-Carrying And Group Members Mediate Walking Speed Decisions In North American And East African Populations, Leah M. Bouterse

Honors Projects

A major portion of humans’ activity-based energy expenditure is taken up by locomotion, particularly walking. Humans can offset the energetic expenditure of walking in numerous ways, both evolutionary (such as changes in body shape) and culturally. Behaviorally, people can choose to walk in a variety of ways, including alone or with a group, carrying loads, and walking quickly or more slowly. All of these behaviors have energetic outcomes and as such can be important windows into how populations and groups adjust to different constraints. While sex differences in speed of paired walkers have been established by others, the dynamics of …
