The New York Times, October 1st, 2010.
Due to a recent discovery by American palientologists in Peru, we have now found fossils of an ancient penguin with feather imprints shown to be reddish brown or gray. The main palientologist, Dr. Julia A. Clarke of the University of Texas claims this as the first scientific look at the development of early penguins, and how they differ from the "tuxedo look of today's penguins. This find is the first look at evolutionary changes of penguins and of all marine vertebrates.
The article fulfills the opinions of the palientologists at the dig who traced the probability of the feather coloration in the penguin. They also seem certain that the penguins shift in color was exclusively changed by the heat of the water and that the current look of penguins developed when the penguins needed more insulation for underwater life. The bias is definitely towards the scientists belief in this one find, and how it can be traced to many factors. This article was pro-environmental due to how it presents the capabilities of nature being responsible for the changes in the penguin as well as the belief in strict species evolution.
