Chinese Boy Claims To Have Cat-Like Night Vision 171

Posted by samzenpus from the all-the-better-to-see-you dept.
Oswald McWeany writes "Reports swirling around the Internet are that a boy in China may have cat-like night vision. The boy with eerie blue-eyes was able to fill out a questionnaire in the dark and his eyes reflect like a cat's when a light is shined on them. No reports yet if he marks his territory or is litter box trained."

    From an evolutionary standpoint, I would think such a radical mutation impossible, unless his family has been selectively breeding for night vision for thousands of years.

    I suspect instead this is just sensationalism and the boy has moderately better vision in low light, without the reflective light collection mechanisms that exist in other animals.

          Iris closure happens in seconds. What you are experiencing is a secondry, slow method by which the eye adapts to different light levels. The concentration of rhodopsin is actually changing. Light breaks it down, but the photosensitive cells continually regenerate it - so when you're in the dark, levels build up and increase sensitivity.

      • Except as the geneticist in TFA pointed out, it isn't 1 gene, its many, many.

        They all produce some change, which is why evolution takes time to produce features or turn them on (and why, say, large portions of the population don't have a mutation to produce Vitamin C). There isn't just a magic switch to turn on adaptations, regardless if our ancestors might have had a trait in the past.

        It took many generations to lose traits incrementally, and will be the same when getting them back in the same way.

        • Your statement is not completely correct. It is possible for a single mutation to effect multiple genes and sections of DNA. These mutations need only occurs in the dark DNA, or junk DNA whichever you prefer. Remember only about 1.5% of the human genome is protein coding exons. How many are silent genes? How many are broken? All questions needing answers.

          A programming analogy might be to say a program is DNA. Running the binutils program “stings” over that program displays all it's possible

          To develop a new trait from nothing, yes. However, a single mutation can prevent a gtreat many genes from being expressed. It stands to reason that an opposite mutation could, generations later, re-enable all of the necessary genes in a single event.

          However, I'd say it's more likely he just has really good night vision on the extreme end of the human norm rather than a novel (for humans) eye structure.

      That isn't how mutation works. There does not need to be a goal for something to happen. This could be the result of a single gene affecting the expression of many proteins, or it could be a mutation that activated some of the dormant genetic material.

      From a reading-that-statement standpoint, I would think you having more than minimal education in the biological sciences would be impossible.

      Mutations are a contributing factor to evolution, not a sole cause of it, or caused by it. There is no "evolutionary standpoint" on a single mutation occuring.

      That being said, it may be an *unlikely* mutation, but with over 7billion people, quite a few people will have rather unlikely mutations. And a single point mutation could conceivably cause a change the density of photoreceptor in the eye, how good they are at capturing photons (the human eye "sees" only about 4-5% of the photons that pass through it).

    In the footage, Nong's teacher claims the boy's eyes flash when shined with a flashlight in the dark, but the reporters don't seem to be able to catch the effect on camera. When Nong's eyes are illuminated in the dark, they appear normal. James Reynolds, a pediatric ophthalmologist at State University of New York in Buffalo, noted, "A video could capture [eyeshine] easily, just like in nature films of leopards at night."

    I can't seem to take a flash photo of my dog without seeing her eyes shine back at me, so I don't see why they can't capture the effect in this boy if it exists.

    I think he's just a blue-eyed chinese boy (which is unusual but not unheard of) with exceptionally good low-light vision, but I don't believe he's developed the same low-light vision adaptation that some animals have.

      • Blue is the "true" color of the eye. Anything else implies there is some pigment - such as melanin - being produced.
        He could have simply gotten a mutation that prevents the eye from secreting melanin, and indeed blue-eyed people are supposedly more sensitive to light. They do, after all, come from those cloudy northern european countries full of pale white people.

        • Shouldn't the true colour be red? As with, for example, albinos, people that don't produce melanin?

        • Blue may be the true color, but not producing the pigment is a mutation. A normal non-mutant eye is brown. This mutation happened before, and the first guy with it was probably very successful with the ladies (after getting past the whole "it's a devil baby" phase, I assume). No reason it can't happen again.

        Anecdotal reports in that class suggested that humans were selectively bred for lousy night vision; those whose eyes glowed in the dark were burned as witches or lynched as werewolves or whatever during the middle ages. Also, physics suggests that increasing light sensitivity by using a tapetum lucidum comes at a cost to resolving power and angular resolution.

        I'd like to see a source for this -- having a human spontaneously develop a tapetum lucidum seems unlikely and details about any human who did so should be well documented since it would be such an unusual case.

        Furthermore, there is no single genetic mutation that could produce a fully formed and functioning tapetum lucidum, Reynolds explained; such an ability would require multiple mutations, which don't just happen all at once. Evolution happens incrementally, he said, not by leaps and bounds. "Evolutionarily, mutations can result in differences that allow for new environmental niche exploitation. But such mutations are modified over long periods. A functional tapetum in a human would be just as absurd as a human born with wings. It can't happen,

      Vision is as much what goes on in the various higher-level parts of the brain as the original physical response of the eye to the stimulus.

      Saying that something that cat "sees" would look desaturated "to us" is open to question because what the cat "sees" is determined by its brain, which we can assume is designed to work with the cats eyes and hence wouldn't "perceive" it as desaturated.
