Global discovery of primate-specific genes in the human genome

In order to discover single-copy primate-specific genes, the authors of this paper screened a catalog of 38,037 human transcriptional units (TUs) and found 131 TUs that were primate-specific insertions across 9 different primate species. They estimate that 46% of these TUs might be protein coding. They also discovered that most of these primate-specific insertions were in organs specific to reproduction; supporting the hypothesis that the order primates arose through biological speciation.
