Question: Of course, evolutionists have long argued that feathers evolved from reptile scales and are thus fundamentally the same structure — very similar.David Menton: Yes — so I became interested in comparing them myself. I had a laboratory technician at the time who had a ‘pet’ boa constrictor, so I took a look at some of its scales from shed skin. I was amused that they were, of course, not even the slightest bit similar to feathers, as these photographs show. The only similarity is that they are both made of the protein keratin — like hair, nails and our skin.
