Critical Evaluation
The lecture is a masterclass in molecular biology and evolutionary developmental biology. Duboule’s explanation of splicing is exceptionally clear, using the dystrophin gene as a concrete example to illustrate the consequences of exon skipping and the therapeutic strategy of exon skipping. The historical narrative of the T locus is engaging and highlights the scientific process, including the contributions of various researchers and institutions. The presentation of the 2024 study is rigorous, with careful attention to the genetic mechanism and its evolutionary implications. Duboule does not oversimplify; he acknowledges the complexity and the remaining questions. The sources cited are primarily the professor’s own expertise and the referenced study, which is appropriate for a lecture. The title accurately reflects the content, and the lecture is well-structured, building on previous knowledge. The only minor critique is that the lecture assumes a certain level of background knowledge, but this is expected for a Collège de France course. Overall, this is an excellent, authoritative, and insightful presentation.
