Document Summary
Coevolution: the joint evolution of two or more interacting species, each of which evolves in response to selection imposed by the other: coevolution is an important process of both micro- and macroevolutionary change. Latter a different predator or parasite adapts to the host clade and diversifies . Ex latex in plants that is poisonous to insects escapes predation and radiates like a motherfucker. Sometime in the future the insects evolve to counteract the latex: phylogenetic detection of coevolution. Figure 19. 2 the phylogeny of endosymbiotic bacteria included under the name buchnera aphidicola is perfectly congruent with that of their aphid hosts. Coevolution their phylogenies correspond to one another and look alike. The bacteria has almost the same phylogentic tree as its aphid host. That"s because the bacteria live in the host and diverse endosymbiotically with their hosts. Figure 19. 3 (a) a phylogeny of specialized feather lice is mostly congruent with that of their hosts.
