Researcher: “I love this paper. It blew my mind,” says David Berson, who studies the visual system at Brown University and was not involved in the research. “What it implies is that evolution has built a visual system that can simulate the patterns of activity that it will see later when it’s fully mature and the eyes are open, and that [the simulated pattern] in turn shapes the development of the nervous system in a way that makes it better adapted to seeing those patterns. . . . That’s staggering.”

Fifty different genes for eye color?
You’ve heard this one before. From the study group: Eye color is “much more complex than previously thought.”
Sophisticated eyes from over 500 million years ago
Okay, but wait. Just because it would benefit a life form to have sophisticated eyes does not mean that it can just start growing them. That’s where Darwinism begins to shade into magic. There’s a missing factor here: How, exactly, were the prey life forms enabled to participate in the complex business of producing vision in response to the predator’s vision?
Trilobites at 429 mya had eyes like bees
Note that we are told that the find “helps track the evolution of eyes and vision in arthropods over time” but in this case, it appears that their wasn’t much evolution: They “developed apposition compound eyes during the earliest evolutionary stages of the group and stuck with this design throughout their history.” No matter the history, Darwin must be placated.
Scallops’ 200 eyes “even more complex” than realized
Take a deep breath and keep repeating “It all just happens randomly somehow. The same random way buildings get built and books get written.”
Convergent eye evolution shows that evolution is “easy”?
Here’s an inventive turn of phrase from Nature: “Eye evolution came easy for simple sea creatures Family tree shows that jellies and their relatives evolved eyes independently at least eight times.” Jellyfish and their kin have no brains and make do with rudimentary nervous systems. But an analysis now shows that these simple sea creatures Read More…
