We provided thus much better phylogenetic resolution than previous studies of this geographic region. Using a Bayesian framework the nomadic populations showed negative growth which was not always correlated to their estimated effective population sizes. Nomads also showed lower diversity values than sedentary groups. Compared to sedentary population of the African Sahel, nomads thus showed signals of stronger genetic drift occurring in their ancestral populations. It is also interesting that the nomadic populations showed a higher North African influence than the sedentary populations of the Lake Chad Basin.
