Jacob’s Understanding of Reproduction: Challenges from an Organismic Collaborative Framework

François Jacob viewed the living world as interconnected by reproductive links, suggesting that biology should not limit itself to studying individual organisms given their ephemeral nature. He believed that reproduction was the cause and purpose of life, asserting that the genetic program played a crucial role in physiology and evolutionary biology, offering a potential unifying framework for biology. While acknowledging the importance of Jacob’s idea of reproduction as a nexus, there are criticisms regarding his reliance on genetic programs. Various approaches to understanding the causes of reproduction—including formal, material, and externally scaffolded factors—are explored and highlight some perspectives that extend beyond the concept of genetic programming. Furthermore, criticisms and objections to the organizational aspects and significance of reproduction in life are addressed. Finally, the relational nature of reproduction is presented as a crucial aspect that necessitates considering collaborative and distributed models.
