Studying house dust mites, two University of Michigan biologists say they have discovered evidence that contracts Dollo’s law – a long standing scientific belief claiming evolution is irreversible.
Scientists at the University of Michigan announced the discovery Friday, saying their research reveals the common house dust mite has undergone “reverse” evolution, changing from a parasitic life form to a free-living one. The study shows the familiar house dust mite evolved over millions of years from free-living organisms into parasites before evolving back into free-living organisms.
