90% of human genome has no functional role, say researchers

  • Over 90% of human DNA plays no useful role, Oxford researchers have said.

    Large stretches of it may simply be biological baggage built up during evolution, the scientists said in a study after comparing the human genome with that of other mammals.

    The scientists compared the human DNA with the genetic makeup of mammals such as dogs, mice, and horses. Parts of DNA, which humans shared with other animals at some stage in history, but which later split from the common pool were examined in the study.
