The relevance of evolutionary distance to immunogenicity and cross-reactivity. Evolutionary distance is given as the length of time to a common ancestor with human beings. Major inhalant allergens are shown with an asterisk. Cross-reactive allergens include (1) scabies with dust mites, (2) cockroaches with ladybugs, and (3) dogs and cats. The mammalian allergens that induce tolerance are shown in red.
