Researchers find evidence of reverse evolution in house dust mites

The study reveals that free-living house dust mites evolved from parasites, which in turn evolved from free-living organisms millions of years ago.

Researchers from the University of Michigan have found evidence of reverse evolution in house dust mites. This discovery contradicts the belief that once an organism has evolved certain traits, it will never again act like its ancestors.

According to a paper published in the journal Proceedings of the National Academy of Science, Dollo’s law states that evolution is not reversible. However, Dollo’s law is still a topic of much discussion among the scientific community. U-M researchers have reinvigorated this debate by locating evidence of reverse evolution that seems to defy Dollo’s law.
