S. Lamichhaney et. al.’s paper was written in a clear and concise manner. The language was easy to understand and not overly embellished. Any technical jargon was explained well and the figures coupled with the text helped facilitate understanding of the data presented. The results of the study are not surprising but then again they should not be. The study is meant to highlight a textbook example of homoploid speciation and the process through which it has occurred. Therefore, the presence of reproductive isolation and the phenotype differences of the hybrids should be expected. The study itself presented a clear example of this rare event in action. As S. Lamichhaney et. al. mentioned, studying a rare event like homoploid speciation is important in increasing our understanding of ecology and evolution. The chance to study speciation while it is still happening is even more significant, especially since this event is happening so rapidly in this example. The study contradicts the idea that homoploid speciation is a slow process by presenting a case where it happens within three generations. Due to the small isolated island setting and the rare chance event of a single immigration, this event is clearly shown. However, this could indicate that even more speciation could be due to these chance events, maybe over longer periods of time or not as strongly shown but still present. This could change the way we think about the formation of species, further study into this is required. Additionally, study of the reproductive isolation of the hybrid against G. conirostris should be done (as S. Lamichhaney et. al. suggested). This will help us gauge to extent to which isolation has happened in such a small time frame.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
