More than 90% of human DNA is doing nothing very useful.
Gerton Lunter, a senior scientist on the team, said that based on the comparisons, 8.2% of human DNA was "functional", meaning that it played an important enough role to be conserved by evolution.
"Scientifically speaking, we have no evidence that 92% of our genome is contributing to our biology at all," Lunter told the Guardian.
1% of human DNA is held in genes that are used to make crucial proteins to keep cells – and bodies – alive and healthy. The latest study, reported in the journal Plos Genetics, suggests that a further 7% of human DNA is equally vital, regulating where, when, and how genes are expressed.
