Figure 4: Location of the selection targets in human populations.
From: The evolutionary history of genes involved in spoken and written language: beyond FOXP2
The gene structures of CNTNAP2 (A), FOXP2 (B), ROBO1 (C), and ROBO2 (D) are shown. Candidate selection targets are shown as triangles, with colors indicating the derived allele frequency of each SNP (red: DAF > 0.80, black: DAF < 0.80). Blue rectangles represent genomic windows with a DH value lower than the 1th percentile (see methods for details). The location of variants cataloged as modern-human-specific sites by56 is shown (gray circles). The black dot in (B) represents rs114972925 (see text).
