Genetic study of house dust mites demonstrates reversible evolution
Date:3/8/2013

r. For example, powerful enzymes allowed these mites to consume hard-to-digest feather and skin flakes composed of keratin.

With the advent of human civilization, nest-inhabiting pyroglyphids could have shifted to human dwellings from the nests of birds and rodents living in or around human homes. Once the mites moved indoors, the potent digestive enzymes and other immune-response-triggering molecules they carry made them a major source of human allergies.
