Self-reproducing systems (SRS) represent ensemble of objects (or individuals) which can produce other objects similar to themselves. If they compete with each other for resources, then they can form aggregates (or clusters) instead of a uniform distribution. New aggregates can split from the previous ones. In terms of biological populations, the aggregates correspond to biological species, and emergence of new aggregates to the process of speciation. Other examples of SRS will also be discussed.
Résumé
Les systèmes auto-reproductibles représentent des ensembles d’objets (ou d’individus) qui peuvent produire des objets similaires à eux-même. S’ils sont en compétition pour les ressources, alors ils peuvent former des agrégats (ou clusters) à la place des ditributions uniformes. Les nouveaux agrégats peuvent se séparer de ceux qui existent déjà. Pour les populations biologiques, les agrégats correspondent aux espèces et l’émergences de nouveaux agregats au processus de spéciation. Nous allons discuter les mécanismes qui régissent ces processus et quelques autres exemples.
