Evolutionary Perspectives of Physical Activity: Comparative Analysis of BaYaka Hunter-Gatherers, The United States and Other Subsistence Populations

总体目标是从进化的角度探索身体活动。该研究主要来自生活史理论，并且主要位于进化医学和行为生态学领域。这篇论文将围绕着一层又一层的比较尺度展开。从巴亚卡狩猎采集者开始，探索群体内体育活动的变化。在此基础上进行扩展，这些群体从事类似的生存模式，但在不同的生态环境中进行比较。最后，比较将扩展到狩猎采集者和发达国家人口之间的跨文化比较，即美国居民的横截面样本。

The overarching aim is to explore physical activity from an evolutionary standpoint. The research draws largely from life history theory, and is largely situated in the fields of evolutionary medicine and behavioural ecology. The thesis will be structured around a layering of scales of comparison. Starting with the BaYaka hunter-gatherers, within group variation in physical activity is explored. Expanding on this groups engaged in similar modes of subsistence but in varying ecologies with be compared. Finally, the comparison will expand to cross-cultural comparisons between hunter-gatherers and populations in developed nations, namely a cross-sectional sample of US residents.
