Median Eyes Discovered in Trilobites, a Problem for Evolution

Trilobites have long been an icon of evolution (Russell Watchtower at the Darwin Ranch has a big 3D picture of one on his wall), but trilobites do not support it. The more scientists study them, the more they learn things that testify of creation and oppose Darwinism.

We saw before that trilobites had exceptional optics, and there is a new development: median eyes, common arthropods. It was long thought that trilobites did not have them. Very useful for sensing objects while critters are moving. This discovery is inconvenient for evolutionary dogma.

Trilobite vision is big problem for evolutionists. First they learned that it is exceptional, then they found median eyes. Storytelling ensued instead of actual science.

For a long time, it was believed that these critters didn't have the extra eye part. The reasons given for why the discovery was late are, well, plausible. Ocelli (median eyes) were put in place from the beginning by the Creator, and evolutionists cannot say they "emerged" or "developed" later. Oopsie! The propaganda mill was put into gear and a Just-So Story emerged. It did not go well.
Many arthropods, including insects and spiders, have “median eyes” or ocelli in the middle of their foreheads. In flying insects such as dragonflies, these ocelli serve as sensors of optic flow, the motion of objects at the sides of the field of vision as the animal moves forward.  . . .

Evolutionists had an argument that ocelli emerged by natural selection on the grounds that some of the earliest arthropods, like trilobites, lacked them. That argument has now been disproved. Trilobites had median eyes after all, and more than many modern arthropods have.
