Certain proteins are expressed in the developmental stages of human embryos (or any animal). These proteins induce the formation of organs. However, if these proteins are continually expressed, cells will become cancerous. I would like for the evolutionists to explain how THAT process "evolved". If evolution is "fact", then the embryo would initially ONLY produce these signaling proteins. Therefore, you could NEVER evolve because all forms of life would become extinct due to the constant upregulation of these proteins (cancer). They would NEVER have the chance to "evolve" and put the 'brakes' on these proteins after initial development (as they currently do).

??? I don't understand the objection here. The regulation of these proteins is mediated by other proteins, or regions of the DNA that proteins bind to, or by the concentration of other chemicals in the cell that are in turn determined by the activities of genes. IOW it all goes back to the structure and sequence of the DNA. Why and how do regulatory mechanisms provide a different or special problem for evolution? It all comes down to the same mechanisms, changes in the structure of the DNA. If structural genes can evolve, so can regulatory ones.

Who would use the words "structure," "sequence," and "regulatory mechanisms" on the one hand, and dismiss intelligent design out of hand on the other hand?
