In my previous essay about proteins-as-design-material, I noted:
This all raises some interesting questions. For example, without proteins, and their manufacturing process, what becomes of the blind watchmaker? Without proteins, and the latent functions contained within, might not the blind watchmaker exist as the impotent, crippled, blind watchmaker with no one to notice its existence? If so, how much credit does the blind watchmaker really deserve?
The vast and immense Tree of Life is a protein-dependent output. Point to some evidence of evolution and I’ll point to the proteins that underlie it. Without proteins, would there be a Tree of Life 3.5 billion years after the RNA world took root? How do we know? If we believe so, would the Tree be as immense and vast as it is today? A life form composed of nucleic acids, carbohydrates, and lipids would suffice for the purposes of the blind watchmaker. But could the blind watchmaker turn this material into something that is analogous to an Ash tree filled with squirrels, beetles, and birds?
