Article Critique

Extracts from this document...


Article Critique The article, "How They Shine," written by Susan Milius talks about iridescence. Iridescence is the effect of a symphony of light shifting with the angle of view. The question that is being asked in the article is iridescence meaningful or is it just pretty? Physicists have been discovering that birds, beetles, butterflies, and many other creatures created cutting-edge optical systems before modern technology did. Now, many biologists and other scientists are trying to answer this question, however many scientist have disagreed upon the answer. In the article, there are many opinions from several different scientists Roslyn Dakin thinks male peacocks have a method to show off their finery to their mates. ...read more.


On the other hand, Richard Prum, a biologist, disagrees with this theory. He says searching for such clues is pointless. He says iridescence may have nothing do with any genetic make up or characteristic of the peacock. He says it could merely be arbitrary or natural beauty. From reading this article, I have learned many things. I did not know there was an effect such as iridescence. A biologist, Helen Ghiradella, has written numerous journals and articles on the scanning electron microscope images of the textures of animal surfaces.

The author did a good job writing the article. She presented the article in a way that is clear, concise, and to the point. It was easy to read and to understand. I do not have much of a science background and I found it very informative. I think the intended audience of this article is anyone in the biology field. I think the article is well suited for the audience. I think the diversified opinions in the article are the strong points. I do not think the author appears to have a bias. I think the article contributes to the field because it offers information that is needed to understand iridescence and it offers different opinions and ideas from a wide range of biologist, physicists, and other scientists. I would not change the article in any way. ...read more.
