Can you describe the test that shows we evolved from fish? How do you reconcile the different proteins that emerged. How do you reconcile the difference is splicing patterns. How do you reconcile how gills turned into lungs. How do you reconcile how fins turned into arms and legs? How do reconcile the origin of hair, skin, consciousness, abstract thought.
The Theobald paper shows similarities which is evidence for common descent. The bigger problem is you need to explain the differences.
The claims of evolution are way ahead of the evidence. So lets go ahead and teach pre schoolers that an untested hypothesis is true.
