Representation of confidence in CAM assignments for LWC chimpanzee samples. The green circles represent 100 point estimates drawn randomly from the set of all possible locations weighted according to their probability. Stars represent the median point coordinate estimate for each sample, color coded according to each sample's mtDNA haplotype from Figure 2. The concentration of these 100 circles in any given area is a guide to the probability that the sample arose from that area, where tighter concentrations of circles indicate higher confidence in the median point estimate. The top panel shows LWC026 with a tight concentration of circles near its median point estimate. The bottom panel shows LWC040 with more dispersed coordinate point estimates.
