L’ADN, acteur et témoin de l’évolution des animaux (3) - Denis Duboule (2025-2026)

The lecture provides a thorough and critical examination of two recent scientific publications on the genetic basis of tail evolution. Duboule demonstrates a deep understanding of the subject, offering detailed explanations of the molecular mechanisms involved, such as exon skipping and the role of Alu elements. He also highlights potential flaws in the first study, particularly regarding dosage effects and the extrapolation from mouse models to humans. This critical approach is commendable and adds to the scientific rigor of the lecture. The second study is presented as a complementary approach, using quantitative genetics to identify multiple loci contributing to tail length variation. This illustrates the complexity of genetic traits and the importance of considering polygenic inheritance. The lecture is well-structured, with clear transitions between topics and effective use of visual aids. However, the technical level may be challenging for a general audience, but it is appropriate for a university-level course. The sources cited are relevant and recent, and the professor’s expertise is evident. Overall, this is an excellent lecture that provides valuable insights into evolutionary genetics and the scientific process.

The title accurately reflects the content, which focuses on the role of DNA in animal evolution, specifically discussing the genetic basis of tail loss in great apes.

9/10

The lecture is given by a renowned professor at Collège de France, based on recent scientific publications, with critical analysis and discussion of methodological limitations. The content is rigorous and well-structured, though it is a single lecture and not peer-reviewed.
