I reject Common Descent because it is an untestable concept devoid of a testable mechanism that can produce the transformations required. T.J. says that using the same genes differently is the mechanism but that dog has been around and still doesn’t hunt. Which genes were used differently?
The chimp’s head sits differently on its spine than ours does. To go from that to us would require changing of the bone structure and musculature. No one has shown that a change in gene regulation can allow for such a thing. Kinesiology also argues against the evolution of birds from non-birds. There just isn’t a mechanism that can produce all of the skeletal and muscular changes required. Muscles have to attach to the bones in the correct places or you get a deformity.
If your mechanism is God did it then you have left science and don’t have a case.
