The number of base substitutions per site are calculated and the evolutionary divergence is estimated between sequences. Each bar represents the total amount of pairwise comparisons of the nd5 gene, or nucleotide sequence divergence, from 50 different Onchocerca species or isolates. Evolutionary analysis was done using MEGA X and a Tamura-Nei model with gamma distribution. Blue bars indicate supposed intra-isolate comparisons and orange bars indicate supposed inter-isolate comparisons of all Onchocerca species or discovered isolates. Lake County, CA and Los Angeles, CA isolate comparisons have been treated as intra-specific species. Gray bars indicate NY-CA isolate comparisons
