Project Abstract: 

Across traditional societies a relationship between growth rate and external conditions has been used to explain observed variability in human growth and body size. Though, some populations, such as east African pastoralists, are known to deviate from expectations. Cross-sectional data on height and weight were taken from a sample of Daasanach individuals (n=223, ages 2-55) from Ileret, Kenya to observe the growth timings of pastoralists to understand the effects of certain external conditions. The results show that Daasanach adult height is consistent with predictions but their growth trajectory is unusual. Daasanach grow more slowly during childhood and experience an earlier adolescent growth spurt over a shorter time than expected.
