The leading creationist scientist Sir Isaac Newton invented the first man-made reflecting telescope, but the scallop had it first, on a tiny scale. In theory, all the Scallop is edible, but it is generally advised to eat only the “meats”, as toxins may accumulate in other parts of the Scallop.”. Animal eye expert Daniel Speiser, from the University of South Carolina, is amazed that such a simple shellfish needs such advanced visual technology, “It’s still a puzzle why they see so well.”2 Of course, the newspaper report contains the required nod to evolution: But how could ‘mastery’ have evolved by slow and gradual changes generated by accidental changes to existing genetic information (mutations), each an advantage over the previous stage? This means that it is almost perfectly efficient at reflecting blue-green light with a wavelength of 500 nm. The roe has a slightly stronger taste which complements well the richness of the scallop meat, but it’s up to your personal preference. long) that explore the biblical and scientific truths of the Bible’s opening chapters. Smithsonian Institution. ... Adorn scallops with micro greens, herbs, and/or edible flowers. In a recent study preprint, Andrew Swafford and Oakley argue that these similarities belie the fact that many types of eyes might have evolved in response to light-induced stress. In the deep history of these components are genetic traits that trigger responses to light-induced stress, such as repairing damage from UV radiation or detecting the byproducts of UV damage. "The main retina in the eye gets almost completely unfocused light because it's too close to the mirror," says Dan Speiser, a vision scientist at the University of South Carolina and the senior author of the new study.

Even the article we are directing you to could, in principle, change without notice on sites we do not control. A new study published in Current Biology reveals that scallop eyes have pupils that dilate and contract in response to light, making them far more dynamic than previously believed. While they are usually yellow (or perhaps on yellow stalks) with blue centers, sometimes only the blue is visible and eyes on dark mantles appear to be yellow or white. Their eyes don’t have irises like our eyes do, and instead, the cells in the cornea change shape by going from thin and flat to tall and long. Food Network. The curved mirror reflects the light onto the interior surface of the retinas, where neural signals are generated and sent to a small visceral ganglion, or a cluster of nerve cells, whose main job is to control the scallop's gut and adductor muscle. Scallop, interestingly, has several food-related meanings; I'll deal with the (eyed) bivalve mollusk first, and then speak briefly about the others.

As light enters into the scallop eye, it passes through the pupil, a lens, two retinas (distal and proximal), and then reaches a mirror made of crystals of guanine at the back of the eye. These contractions can change the curvature of the cornea itself, opening the possibility that the scallop eye might change shape and respond to light in a way that makes it possible to form crisper images on the proximal retina. So next time you are enjoying some garlic scallops, try not to imagine the mollusks staring back at you. Scallop (noun) an edible bivalve mollusc with a ribbed fan-shaped shell. These scallops have greatly declined due to the usual coastal problems, mostly from development, but also from over-harvesting of the sharks that ate the rays that eat the scallops. Once the suite of genes involved in detecting and responding to UV damaged are expressed together, then it may be just a matter of combining those parts in a new way that gives you an eye, the researchers suggest. She believes that the opsins, in most cases, are being repurposed from some other function within the animal to be used in the eyes. Opsins are light-sensitive proteins found in the photoreceptor cells of the retina that mediate the conversion of light into electrochemical signals. And then, how does it become specified to the different types of light environments that the animals can occur in?” Serb asks.
