Purpose
The article in question dwells upon the fin-to-limb transition and the latest discoveries in this field. The researchers provide a brief analysis of major findings in the paleontological and genetic research (Freitas, Gomez-Skarmeta, and Rodrigues 8). This article provides valuable insights into the most recent research. The purpose of the study is to unveil the mechanisms of the evolution and change of fin to limb. It is necessary to note that the article in question supports the ideas revealed in the article studied in class. More so, the same experiment is used when it comes to genetic research. However, the researchers provide more details and unveil some of the mechanisms of the evolution.
Methods
The researchers used a morphological analysis of fossils and skeletons of modern animals, which supports the idea of the transition of fin the to limb. As for the genetic research, the researchers consider the same experiment with embryos of mice and zebrafish.
Results
According to the article, HoxA genes are central to the evolution of fin. It is also stressed that, in animals that have AEF, a specific barrier to developing fins has developed.
Conclusion
On balance, it is possible to note that the article provides valuable insights into the transition from fin to limb. The researchers have identified the occurrence of a certain barrier. However, it is still unclear why this barrier occurs. Hence, further research is necessary to get a full understanding of the process of evolution.
