The following two papers deal with two independent research projects, but are very similar in their questions, implementation and evaluation. They were even published in the same journal. However, there are significant differences in the interpretation of the results and in the narrative style. Saenz et al. (2012) tries to put the results into a biological context. He refers to comparable studies and provides detailed explanations. The paper by Narain et al. (2015) is more technical. The results are soberly presented without much biological background. It is interesting to compare the two studies in terms of the results and especially the interpretation in the context of population structure.
