"Genomes are littered with nonfunctional pseudogenes , faulty duplicates of functional genes that do nothing , while their functional cousins ( the word does n't even need scare quotes ) get on with their business in a different part of the same genome . And there 's lots more DNA that does n't even deserve the name pseudogene . It , too , is derived by duplication , but not duplication of functional genes . It consists of multiple copies of junk , `` tandem repeats `` , and other nonsense which may be useful for forensic detectives but which does n't seem to be used in the body itself ."
"Luckily science moves forward and these arguments from ignorance get left behind and the proponents of these arguments fade into history as proponents of ignorance trying to sell meaningless metaphysics . Junk DNA is a myth . Examples abound of research finding fascinating functions for these previously thought non-functional parts of the genome ( out of ignorance and bad metaphysics -- Dawkins : `` And there 's lots more DNA that does n't even deserve the name pseudogene . '' ) . Model unravels rules that govern how genes are switched on and off"
