Süper çözünürlüklü gören insanlara deniyor.
bu “süper insan”lar, normalde insanların gözlerinde bulunan 3 tip koni’ye ek olarak 4 tipi de bulundururlar.
bizdeki koni hücreleri 3 dalga boyunu ayırt edebiliyor. 3 ana renk diye geçiyor; kırmızı, yeşil ve mavi.
onların dördüncüsü bizim göremediğimiz yeni keşfedilmiş bir ana rengi değil de, var olan renkleri daha derinlikli görmelerini sağlıyor.
yani bizim kıpkırmızı göreceğimiz bir alanda, farklı bir renkte değil ama kırmızının tonlarıymış gibi bazı şekiller görebilirler.
yeni bir renk ya da ultraviyole ışınları görmüyorlar yanlış anlaşılmasın.
bu şanslı elemanlara süper insan diyorlarmış.
bu süperlikten ziyade mutasyonla oluşmuş bi anormallik aslında, şu ana kadar bu gen “bozukluğu” dolayısıyla kadınlar “süper” görürken, erkekler renk körü oluyor.
bu da iyi ve kötü mutasyon örneklerini göstermesi açısından güzel bir örnek oluyor.
yabancı bi profesör abimiz sitesine test koymuş, üç daire var, küçük dairelerden oluşmuş, 3 ayrı renkte, dairenin içinde herhangi bir harf(ya da simge vs.) görebiliyorsanız süpersiniz.
gözlerinin evrimleşmiş olabilecek kadar iyi olduğunu düşünen, geleceğin süper kahraman adayları buradan ekstra bilgi alıp kendilerinde böyle bir özellik olup olmadığını kontrol etmek için profesörün blog’una göz atabilirler;

If you see in one field more than one colour – maybe you are a tetrachromat 😉
A woman has been found with superhuman sight that enables her to see 99million more colours than the average person.
It took 20 years of hunting, but a dedicated scientist has found her Holy Grail: A woman who can see 99 million more colours than the average human being.
While she can’t see through walls or turn her eyes into a heat ray, the unidentified woman is a ‘tetrachromat’, with the ability to see much greater colour depth than almost everyone else in the world.
Dr Gabriele Jordan, a researcher at the Institute of Neuroscience has spent the last 20 years on a mission to find someone with superhuman sight.
Vision is one of the most complicated of the senses, and how the eyes perceive colour is broken down by ocular cells called cones.
Most people have three types of cones, and are described as being ‘trichromatic’.
Individuals who are colour blind have only two types of cones, making them dichromatic.
Discover magazine reported that while Dr Jordan and her team found several tetrachromats, only one could pass her test, which included showing three coloured circles with a difference that no one but a true tetrachromat could detect.
Running colours: Vision is one of the most complicated of the senses, and how the eyes perceive colour is broken down by ocular cells called cones
That woman, who has only been identified as subject cDa29, is a doctor living in northern England – but others may be out there.
Dr Jordan told Discover that the findings had her ‘jumping up and down.’
But with their tetrachromat comes a conundrum: How is one woman’s vision so advanced when others with the same four cones were not?
She told the magazine: ‘We now know tetrachromacy exists. But we don’t know what allows someone to become functionally tetrachromatic, when most four-coned women aren’t.’
And why not men? Research on colour blindness dating back to 1948 found the condition appeared to run in families, but didn’t affect women.
Dutch scientist HL de Vries, who wrote the paper, suggested that females recognised colour differently, thanks to that fourth cone.
na was sagt uns das mal wieder über die Frauen? ;-))
this is an example to imagine how people with only two cones see a scene (colour blind) and people with three cones (normal). The next step is a tetrachromat, but I think theres no picture to show… Tetrachromatic people must see the world also brighter than we can see. Many animals have this option too (like birds and fishes) They have mostly an UV-cone to see UV-light.
