Hey guys im sorry to say but, the guy is 100% right, in nature a color mutation will most definitaly result in the death of that animale, like to describe it as this. here is how i learned it from my professor.( but it could go both ways) for instance we will take moths for example,, in a forest where these moths live, the trees are covered in mossy grey light brown bark. and these moths live in and around these trees. now lets say a bluejay is hungry but the only defence these moths have is their color which is similar to the color of the trees so it basically is hidden, but in among the moths there are a few 1000 that are the same species of moth only white colored mutation, these moths will be eatin before the normal colored ones because the blue jay could easily see the moth, but as i learned from studying nature the enviorment is always changing, now the trees begin to white out and change color and become more white in color than grey and the moss dies, now the mutation has a better camo than the normal moths and will die before the white. and as for the weeker skin and blindness, there are different effects albinoism has on different animales and sometime individual animals, and or species. but its perfectly normal to have mutations in that is evolutions way off testing new colors and and seeing what new species may arise or what new colors would work better for survival. What i wrote here is not BS and is true, i am a bio major and am pretty smart...lol
