"Sure it does." - Ichneumon
Actually I understand that 50% of your genes resemble a banana. But that is equally applicable to common design as common descent. It in no way proves common descent.
The evolutionist's claim of 98% identical to a chimp was false. As you don't even share that much with your parents.
The key question is, not what percent is identical, but rather, how many changes must occur to be transformed from one to another. The number is huge and is not likely to have happened by chance or by natural selection alone.
If B resembles A, then A must be the source of B. A common source C is not possible.
