They don’t believe in evolution? No, apparently not.
Most people don’t, across North America, it seems.
Some idea why not, from a pop science article
An unusual arrangement of particles has been discovered in the cells of chicken eyes. It’s the first time scientists have seen such a system in a biological system — one that allows materials to behave like both a crystal and a liquid.
The unique arrangement is called “disordered hyperuniformity,” and it could help researchers design advanced materials, such as optics that can transmit light with the efficiency of a crystal and the flexibility of a liquid.
It has to do with the way the chicken’s four photoreceptors — violet, blue, green, and red — and a fifth light-detecting type are crammed into a single tissue layer on the retina. Finding a way to organize these five elements in an optimal way is a huge technical challenge (which is called a “packing problem) — but evolution found a way.
“Evolution,” used this way, = “magic” and we were all told not to believe in magic.
