Gould And Lewontin Summary

Some forty years ago, Gould and Lewontin published an article called The spandrels of San Marco and the Panglossian paradigm: a critique of the adaptationist programme. This article resembles Dobzhansky 1973 work based on the similar dynamic created between religion and evolution. This shows a consistence religion aspect in most evolution writing on theories; however, in Dobzhansky 1973, he tried to persuade people to “convert’ to evolution. Furthermore, Gould and Lewontin argue about the Spandrels and its adaptation cost compared to organism’s adaptation provides the reader a great read. Although Gould and Lewontin’s article has several positives, it also has some negatives as well. For instance, one critique of their thinking is that it just …show more content…

There are several ways to support a dome on four arches. For example, you can have pillar that hold up the vaulted ceilings (I watch a video on this in my art history class).Therefore, the builders at the time had to choose a design for the churches, like the St. Mark’s Cathedral, so they chose the only one known at the time to be able to hold the dome. Specifically, the spandrels described earlier are actually adaptive because they formed from the benefits of its structure. There whole point for the use of “Spandrels” in this article was to comment on unsupported theories about adaptation. Ironically, Gould and Lewontin’s spandrels analogy are being just that; thus, making it an unsupported opinion. Therefore, I would suggest Gould and Lewontin to stick with what they know and don’t try to incorporate information from fields that they don’t fully understand. Dobzhansky, a genetics professor, made the same error in his 1973 work by referencing astrometry, which brings many critics through future research. Furthermore, I would use art in general sense because, although numerous works do have meaning, a baby’s scribble has no meaning. Thus, this signifies that there is no purpose for change, non-adaption. It seems that evolution biologists are better off when they focus on a system, like development, living, and evolution itself, than analogies, which is for English …show more content…

Ironically, Gould & Lewontin never explain how the growth in complex in functions that alludes to organisms that exist today can show these developmental constraints and allometry. Next, Gould and Lewontin discuss how important forces besides natural selection are, but they completely miss all kinds of interesting questions that can be asked about the interplay between multiple evolutionary “forces”. They talk as if these other forces are alternatives to natural selection, when in fact it’s typically the case that all these forces co-occur and really surprising phenomena arise from their interplay (it’s not always that the “strongest” force just swamps all the others). For instance, developmental systems themselves vary and variation in developmental outcomes has fitness consequences, so developmental systems are subject to selection as well as constraining the phenotypes that an organism can build. So how do developmental constraints themselves evolve? Can organisms evolve to become more “evolvable” (e.g., to have more atomized traits)? Indeed, near the end of “Spandrels” Gould and Lewontin actually raise, and then dismiss as uninteresting, the fact that similar phenotypes can have different developmental underpinnings. Presumably, Gould and Lewontin are reluctant to even ask these kinds of questions because
