The Advantages of Color Vision Essay

Professor Fisher, in 2004, said that color affects human beings in many ways, on both the conscious and subconscious levels, every day of our lives. As Professor Fisher stated, color affects us so many times a day, that often times we don’t even realized it’s happening. Think about all the things you have done today, that in someway involved color. For example, think of a stoplight and what each color on it means; without those colors we would not have the technology of a stoplight and therefore our everyday driving wouldn’t be quite as easy.

Food requirement variations lead to color vision being an exponentially valuable trait in the evolutionary success of the primates based on its influences in foraging behavior. If an animal is unable to discriminate a piece of fruit from being ripe or unsafe to eat, they could potentially become sick, thus negatively impacting their chances of reproduction and survival (Regan et al., 2005).

Lead Geneticist Bryan Jennings of Boston Medical Center says that ‘the possibilities could be endless, with proper research. For now, we’re starting small. Instead of hearts or blood or digestive organs, we are testing eyes.’ Mantis shrimps are creatures found in warm, shallow water. The shrimp’s most valuable quality for genetic purposes are the sixteen color-receptive cones in it’s eyes. Essentially, the color spectrum visible to humans is developed by just three color-receptive cones over the retina. That means billions of colors humans miss that mantis shrimp can see. The new process involves surgery that extracts all of the cones in humans, and replaces them with all of the mantis shrimp

Taking a color blindness test is extremely useful, because you may not know if you are color blind. By taking the test I had mixed results of Tritanomaly and Tritanopia and normal vision. When I first took the test Tritanomaly and Tritanopia were my results. Tritanomaly and Tritanopia is a mild color blindness to certain hues of blues and yellows. So, this means that to me some blues appear more green and yellows can appear to me as violet-gray. I did more research on this form of color blindness and it is from a lack of blue cone cells and is also extremely rare autosomal recessive disorder in men and women. Just for safe measure, I decided to take the test

+ Raccoons have weak eyesight and are color blind they rely mainly on their keen sense of smell.

Organisms possess several types of color vision depending on what wavelengths they are sensitive to. Humans are trichromatic, because their vision is formed by long, middle and short wavelength sensitive cones (Carroll, et.al, 2009). Depending on the environment, primates will have different variations of color vision. (Melin, et.al, 2017). Routine trichromacy and polymorphic trichromacy both track different food sources. Routine trichromacy is helpful for tracking down reddish-yellow fruit and seasonal leaves while polymorphic trichromacy is helpful for tracking down ripe fruits and insects (Melin, et.al, 2017).

AH4: That male brightness is determined by a combination of predation, geographical isolation and/or sexual selection, predicting that two of the previous hypotheses are supported.

Vision-- receiving and interpreting light signals from the environment in order to form an image in one's mind-- is an incredibly complex process. Somehow signals from photoreceptors located in the eye are converted into the conscious experience of sight. Of all the aspects of vision, perhaps the most difficult for us to comprehend scientifically is this notion of consciousness. Somehow the brain interprets light waves hitting the retina so that we are visually aware of our surroundings. While the mechanism of signal transduction from the photoreceptor through the visual cortex has been extensively elucidated, science has difficulty dealing with the phenomena of consciousness

The article “Gene therapy for red- green colour blindness in adult primates” by Katherine Mancuso and her colleges is about the possibility of curing color blindness. This test was done on adult squirrel monkeys that were missing the L- opsin gene. Out of the three cones humans have (short (S), long (L), or the middle (M) photoreceptor) only the L-or-M cone is responsible for red- green colour blindness. Many female squirrel monkeys have the ability to access all three photoreceptors giving them the ability for trichromatic color vision, but males are dichromats meaning they are missing the L-or- M gene causing them to be color blind. In order to correct this color deficiency a third type of pigment was added to the monkeys retinas to provide them with the receptors that are necessary in order obtain trichromatic color vision. Over the span of a year the scientists observed that before the treatment the monkeys couldn’t decipher between blue green and red violet. After they started to develop a new pigment (due to the injection) in the cone photoreceptors scientists discovered that the monkeys now reacted to the colors they couldn’t see before. The scientists concluded primates benefited from the injection and that they were able to see colors they were invisible to them before, and that the findings in this experiment could

Their eyes, and vision are analogous, since they are bitten by mantis shrimp, in more details, the mantis shrimp known as not endangers, yet when they bites on people’s body, the sting of a the mantis shrimp has swollen up, either, causes serious loss of vision. According to the current research, mantis shrimp is very tiny, and their habitat is normally in shallow ocean. Therefore, at first people discern no difference, and did not even realize it was occurring. Those of evidences are still convincing with people’s perspective, such as people usually distinguish many colors, and it is now a proven fact that people truly conceive that they are normality. Therefore, majority opinion is more significant than the minority one, and which is one of the evidence that expressed that still many color-blinded either dismiss from the people or a world. However, resume the thread of our discourse, the mantis shrimp see the color differently such as red to brown, and green to black. Those of the facts that only prove by the mantis shrimp, since many of the people born with their unusual ability of the eyes. Actually, we are the inability to distinguish particular

Couple 3 comes into your office. The husband is color blind; the wife is heterozygous for the color-blindness allele.

In evolutionary terms colour and the way it is perceived is an important aspect. Sumner and Mollon (2000a) conducted research looking into the photopigments and the detection of targets. They found that the L/M subsystem provides an advantage for the detection of fruits and leaves. This led them to their conclusion that finding these foods may have been an essential selective advantage in the original development and maintenance of primate trichromacy, and thus the process of colour perception can be beneficial to primates. Despite having the same visual system, the research is problematic as it was conducted on animals, and thus the findings may not be the same when applying it to the human concept of colour vision. Further support towards the evolutionary basis of colour perception comes from Bompas, Kendall and Sumner (2013) who found that normal trichromats made faster responses and fewer errors than their colour deficient competitors. This shows that colour is an important aspect and both of these research findings combined suggest enhanced survival due to the way in which colour is

Almost all animals and a fair amount of plants are photosensitive. Photosensitive is the ability to detect and react to light. Many organisms can only recognise simple light, and react to them, however their eyes are not developed enough to recognise colour or images. To be able to form an image, an organism needs far more developed eyes. Almost all vertebrates, and some more

Estimation of LV mass in epidemiological studies, the diagnostic classification of LV hypertrophy, and studies of the effects of therapeutic intervention must depend on reliable and comparable measurement techniques. For long time, the gold standard for estimation of the cardiac mass was autopsy. Over the last decades, and due to the advances in the different imaging modalities and the new evolving technologies, many techniques were developed to estimate the LV mass. Notably, each technique has its pros and cons, and its own rate of accuracy in prediction of the LV mass compared to the gold standard. Different cut off values were developed for each technique.

Based on the findings that one has discovered in life itself, in essence, color helps with the flows of life in a way that it can determines your thoughts, emotions, and decisions. In my research I gained a vast amount knowledge and from what I’ve learned; now I can explain colors in depth, with a great amount of detail. If colors were non-existent, then, there would be a very grey look upon life. Colors brings forth light, and the light brings forth living. The world displays colors for a reason and it’s very important to life.
