Topic > The Triple Helix and the Finch's Beak - 1716

The Triple Helix written by Richard Lewontin and The Finch's Beak written by Jonathan Weiner transport the reader into the world of evolutionary theories. Although both authors discuss the evolution of species, they take distinctive and different approaches as they describe to the reader their specific scope of evolution itself. These differences are visible in both novels, and the conclusions drawn about evolution by both authors challenge each reader's individual beliefs about natural selection, genes, and the environment itself. Lewontin acknowledges that The Triple Helix has a "definitely negative flavor" (p. 109). ) to explain how a reductionist approach can lead us to formulate an incomplete picture of the biological processes of living organisms. Although the author may have written the book with this mentality, The Triple Helix reiterates that genes are not the only factor for the development of living organisms, but it is an extraordinary relationship between genes, organism and environment that influences biological processes so that an organism develops. success. The first chapter of Lewontin's argument, “Gene and Organism,” focuses on the problem of relying on genetics for all responses to organismal development. For example, Drosophila (or fruit fly) has a mutation in the development of the head. A normal fly has antennae, while Drosophila replaces the antennae with “leg-like appendages” (Figure 1.2, page 15). Lewontin explains that these dramatic genetic mutations convince established biologists that variation within organisms must have occurred due to genetic differences (p. 15). However, the environment plays a huge role in the development of the organism, “a unique interaction between genes and [an organism], and random… half of the article… researcher points to the value of Lewontin's theory on evolution. The dynamic processes of Grant's findings, however, would not ideally fit the Triple Helix. To conclude, Richard Lewontin's The Triple Helix and The Beak of the Finch, written by Jonathan Weiner, engaged the reader to view evolutionary theory through juxtaposed lenses. While Lewontin has strong opinions towards modern evolutionary biologists, Weiner praises Peter and Rosemary Grant for their work following Darwin's On the Origin of Species. Finally, the conclusions reached by both authors transport the reader into the fascinating world of evolutionary biology and all its differences. Work cited Lewontin, Richard C..
