Intelligent Design in Nature Scientists have found that all life is DNA controlled, from bacteria to fish, birds, insects, animals and mankind. The great surprise to biological researchers since about 1990 has been that DNA is coded in a precise digital language with about 3 gigabytes of complex well-integrated information. At first they thought that much of it was junk DNA, but then they discovered that it all has a purpose. It is apparent that such complex digital programming could not have occurred accidentally, and evolution may be able to explain changes, but it cannot explain the origin of DNA in the oldest life forms. The intelligent origin of DNA information supports Creation, not Evolution.
