Critical Analysis On An Article – Article Example
Multicellularity is one of the major components of the current biological landscape, but researchers know surprisingly little about how it evolved. The purpose of the article in question is to explain some of the current research currently being undertaken on Volvox and Chlamydomonas to find out the genetic underpinnings of this trait. Through outlining the genomics and functional genetics of these organisms with respect to current research, Miller (2010) explains that there is relatively little difference between the genetics of unicellular and multicellular organisms. The article contains a lot of relevant and well-written information which clarifies the current research on the evolution of multicellularity.
The reading itself focused particularly on two types of organism that researchers believe hold the key to explaining the evolution of multicellularity, Volvox and Chlamydomonas. To do this, Miller (2010) explains the nature of multicellularity and places the research regarding the two organisms in context. For example, glsA has been found (using developmental defects in Volvox) to be necessary for asymmetric division, which is placed in the context of multicellularity. The arguments for how this information underpins the evolutionary theory are strong because Miller (2010) asks rhetorical questions that are similar to the questions that develop in the readers head, and answers them scientifically using more research.
Overall, there is a lot of information contained within the article. This is perhaps a weakness, because it makes it difficult to comprehend how much evidence there is for multicellularity. However, the sheer amount of research covered and the depth in which Miller (2010) covers it makes it easy to see how well the thesis is supported by current research. Adding more general information for a less scientific reader (such as the basics of multicellularity) help understanding and make it easy to follow and agree with the argument that unicellular and multicellular organisms have only small genetic differences.
The reading definitely enriched my knowledge of the topic, as I had previously been unaware of the specific genes that have been shown to play a role in multicellularity, like glsA and the invA, invB and invC group. The way that these were explained in context was also very useful for my understanding. It is different from a lot of the other readings on the topic as it provides a clear summary at the end that clarifies the viewpoint that Miller (2010) has on multicellularity and its evolution.
