Manning suggested that inter-ethnic differences in mean digit ratio were a function of latitude, with populations at intermediate latitudes having the highest digit ratios and those at the equator and at high latitudes having the lowest. This trend was seen in the populations studied in Manning et al… CONTINUE READING
