Albino Cyclops Shark Confirmed Authentic

Cut from the belly of a dusky shark by commercial fishermen off the Gulf of California, researchers and experts have agreed that the remains are real; one of less than 50 known examples of a working optic nerve in cycloptic sharks.

Via: Shark expert Felipe Galvan Magana, of Mexico’s Centro Interdisciplinario de Ciencias del Mar, told the Pisces Fleet Sportfishing: “This is extremely rare. As far as I know, less than 50 examples of an abnormality like this have been recorded.”

Researchers said they had examined the shark and found that its eye was made of functional optical tissue. It is unlikely that it would have survived.

Dr Magana and his colleagues will soon publish a scientific paper about the find.

Seth Romans, a spokesman for Pisces Fleet, told LiveScience that the fisherman who caught the shark was “amazed and fascinated” by the attention and was hanging on to its remains.

A pretty awesome example of how drastic some mutations can be.  I doubt something like this would be adaptive, but it just goes to show a little change in genetics can deliver a radical change in morphology.

Pre-historic beetle preserves its color
An amazingly well preserved beetle fossil still retains its color - 47 millions years after it came to be.

 
Despite being tens of millions of years old, some beetle fossils appear almost as they did in life. Not only are their shape and structure preserved, but so are the actual colors of their shells, which have changed only slightly in the intervening eons.
Though relatively little-known, these fossils represent the purest of biological colors retrieved from deep time, far richer than much-celebrated pigment traces of dinosaur plumage and more varied than the hues of a few ancient plants.


I wonder if it is the case that the color of the beetle is due more to diffraction effects or pigmentation.  If it is diffraction then perhaps the reason it is preserved is because the microscopic structures on the beetle’s carapace are unaltered during the fossilization process.

There are two threads that run through our Anointed authorities. The first is an appealing “Christianizing” of the ideas. David Barton “Christianizes” American history; Ken Ham “Christianizes” the science of our origins; James Dobson “Christianizes” social science, including the definition of the family. The “Christianizing” of these ideas, by default, undermines the credibility of secular ideas that might challenge the positions promoted by the Anointed leaders. The second thread is old-fashioned American anti-intellectual populism. Barton, Ham, Dobson, and other Anointed leaders tend to make no effort to engage the fields they claim to represent. Barton never subjects his claims about American history to peer review in a journal. Ken Ham and James Dobson do no scientific research. In the secular world ideas get vetted in the academy through peer review in technical journals; then they appear in serious but more popular outlets; and then finally they might get discussed on the radio. The ideas of the Anointed cut out all these middlemen and appear immediately on the radio or television.


In the cottony cushion scale—a common agricultural pest that grows to about a fifth of an inch (half a centimeter) long—a new phenomenon has arisen: When some females develop in fertilized eggs, excess sperm grows into tissue within the daughters.
This parasitic tissue, genetically identical to the female’s father, lives inside the female and fertilizes her eggs internally—rendering the female a hermaphrodite and making her father both the grandfather and father of her offspring, genetically speaking.

The tentacled snake uses its special appendages to detect fish in the water
Aside from its helpful adaptation, the tentacled snake (Erpeton tentaculatus) is a devastatingly effective hunter. Snakes are instinctively born knowing how to lure fish into a trap formed by their J-shaped body. The snake then startles the fish with a slight movement of the snake’s abdomen, initiating the fish’s escape instinct and manipulating it to drive the fish right into the snake’s mouth. If the fish takes an alternate path, the snake strikes at the location where the fish will be milliseconds later - even before the fish has started moving.

I have always wondered if the very similar protuberances on marine eels had a similar function.

"our tendency to detect intelligent agents when none are actually present"

I think that HADD is crap. If anything, our tendency as humans is to fail to give the benefit of the doubt to other humans let alone other species as far as intelligence and equality. Mythology is not the result of mistaking inanimate objects for spiritual entities, rather it is the natural function of the human psyche to express superlative qualities as personified characters. It is a playful, fictive process which is interpreted in a variety of ways, ranging from simple entertainment to social drama to sacred revelation and has nothing whatsoever to do with survival or evolutionary biology.

Obviously whatever we have in the way of signifying sentience is present in other life forms as well - not as an independent phenomenon but as an aspect of being a living organism as opposed to a dead one.

Oh?  I suppose you have some other hypothesis or data to present?  ”Natural function of the human psyche”?  Why does it have that function?  ”Playful fictive process”…that means nothing and explains less.  Everything about human physiology and psychology has something in principle to do with evolution.  We are not privileged to have received some of our qualities by providence or magic rather than evolution like everything else.

Listen my friend.  I have tried before to get you to realize that you speak about science and physics in a way that may make you appear intelligent to those unfamiliar with the subjects, but it is obvious to those with formal schooling that your knowledge is superficial at best.  Your pronouncements are based on wish-thinking and fuzzy logic.
