Summary:

This article tells us that biologists have found a new species of spiny pocket mouse, which is called Heteromys catopterius. And makes a comparison between the Heteromys catopterius and Overlook Spiny Pocket Mouse, in order to explain why this kind of mouse is a new species. There are a lot of differences, such as the Heteromys catopterius ‘ fur is darker than that of the Overlook Spiny Pocket Mouse and this mouse doesn’t have obviously rounded ears. Besides, the skull of H. anomalus is broader and shorter. The Overlook Spiny Pocket Mouse usually lives in the place which is from 350 to 2,450 meters higher than the sea level. But the H. anomalus lives in the mountains of the area or some forests , which are lower than this number. Many people are very surprised that we still have a new mammal species, which we could not find in the past. Most new species are found in some genetic work; biologists need to check the data when they identify an isolated species. But this time, the new species is a special one; researchers had never paid attention to it. Professor Anderson, who found the H. anomalus, explains that if there are distinguishable changes from one place to another place, more likely we can find new species between these two places. In addition, Professor Anderson is a monitor of a group which does research about “geographic information systems (GIS)”. His purpose is to connect the Heteromys and GIS , do research about the requirement of climate and make a comparison between the suitable habitat and location habitat.

Reaction:
After reading this article, I found that there still are some dead angles that our science cannot touch. This new species is a branch of the spiny pocket mouse, so the biological scientists never focused on it. Through this case, I realized that our nature has varied species; human is just one kind of living thing in the natural world. Human’s science, power and wisdom cannot be mentioned of the same time with our nature. I believe after this discovery, we will find other new species in the future. On the other hand, I am glad to hear this news, because we can get clues and more information to fill in our zoology data store house. Like professor Anderson, we can use the new species to do some research, which can help improve our life. As we know, all the science research or experiments serve our human beings; the purpose is of improve our life,and our living environment. Because now, the natural environment has become worse than before, all the scientists try their best to save our earth; therefore we need more patience. As for me, even though I am just a student, I still can learn the spirit of scientists, and use this spirit in my daily study.
