We used calculated summary statistics describing genetic variation and used coalescent-based methods to estimate population genetic parameters. We find that the Joshua trees are moderately genetically differentiated, but that they diverged quite recently (~100-200 kya), and much more recently than their pollinators. The results argue against the notion that coevolution directly contributed to speciation in this system, suggesting instead that coevolution with pollinators may have reinforced reproductive isolation following in
