Human and chimp genomes quite different

Research has shown that the often repeated 98%-99% similarity between human and chimp DNA is misleading. A thorough review of evidence has put the similarities at 85-59% maximum.

The DNA similarity figures are often used to claim support for human and chimpanzee descent from a common ancestor, but are misleading. They have tended to ignore non-coding sequences, so called  'junk DNA' which is increasingly being seen as more important than had previously been thought. Almost nothing is known of how the proteins such as collagen are actually assembled and put into place, just producing a lump of collagen is no good, you need working tendons attached to the right places at each end, etc. This higher order assembly instruction information, which is not observed to be produced by untintelligent processes, is most likely located in the so called junk DNA which is usually omitted from DNA percentage comparisons.

DNA similarities can equally well be taken to signify common design, there are after all only so many ways to build bone, hair, skin or muscle. Krebs cycle and other very fundamental metabolic processes are common to all living things so there is bound to be a huge amount of similarity in DNA between cabbages and kings, lettuces and lemmings etc.

The reality is that far from supporting their case as they would have us believe, DNA poses numerous insuperable problems for the Darwinian, not least since it and its associated check and repair mechanism are irreducably complex and are built by proteins and nanomachinery which it codes for, the mother and father of all chicken and egg situations.
