Casey Luskin examines a paper which argues that the famous beta-globin pseudogene is functional. Why is this pseudogene famous?
If mutations are the raw material for evolution, they are like explosives with unpredictable effects.
Long described as useless leftovers of evolution, pseudogenes are rising from the junk pile as functional entities.
As Seth W. Cheetham and his co-authors put it, biology suffers from “demotivation into exploring pseudogene function by the a priori assumption that they are functionless.”
Scientists watched microbes inherit extreme acid resistance in Yellowstone hot springs not through genetics, but through epigenetics.
