Which interpretation(s) of the comparison between this host and parasite phylogenetic tree from Moran & Bauman 1994 paper could be correct? bacteria Buchnera aphidicola Ruminobacter amylophilus Proteus vulgaris Escherichia coli Schlectendalia chinensis Melaphis rhois -- Pemphigus betae Mindarus victoriae--- Chaitophorus viminalis Diuraphis noxia Acyrthosiphon pisum Uroleucon sonchi Myzus persicae Rhopalosiphum padi Rhopalosiphum maidis- Schizaphis graminum---- aphids 48-70 My ago 80-120 My ago 30-80 My ago 80-160 My ago origin of endosymbiotic association Fig. 1. Phylogeny of the primary symbionts of aphids (Buchnera aphidicola complex) and phylogeny of the corresponding aphid hosts. The bacterial phylogeny is based on 16S rDNA sequences18.19; the aphid phylogeny is based on morphology21, Dashed lines indicate associations. Taxa within Buchnera are represented by names of their aphid hosts. The concordance of the two trees supports synchronous parallel cladogenesis of aphids and Buchnera. Dates are estimated from aphid fossils and/or biogeography; they apply to both aphid and bacterial ancestors. Parasites and hosts are co-evolving and therefore their evolutionary lineages have been co-diverging too. Parasite lineages diverged whenever the lineages of their hosts diverged too. The evolutionary divergence of the parasite is linked to the evolutionary history of the host. All of the above could be correct.
