Cosmological natural selection also called the fecund universes, is a hypothesis proposed by Lee Smolin intended as a scientific alternative to the anthropic principle. It addresses the problem of complexity in our universe, which is largely unexplained. The hypothesis suggests that a process analogous to biological natural selection applies at the grandest of scales. Smolin published the idea in 1992 and summarized it in a book aimed at a lay audience called The Life of the Cosmos.

- La selezione naturale cosmologica è un modello cosmologico proposto da Lee Smolin, esperto di cosmologia quantistica e gravità dei quanti ma presente anche in altri modelli, che prevede la nascita di vari universi (che formano un infinito ed eterno multiverso) da un universo precedente, in modo che venga selezionato probabilisticamente, analogamente a quanto accade in biologia con la legge dell'evoluzione scoperta da Charles Darwin (in cui vince la lotta per la sopravvivenza l'organismo più adattabile), il più adatto alla vita intelligente (secondo il metro di giudizio "umano"). In questo modo è nato, casualmente, questo attuale universo, dove si trova la Terra. (it)

- La théorie de la sélection naturelle cosmologique (ou des univers féconds) proposée par Lee Smolin en 1992, suggère qu'un processus analogue à la sélection naturelle biologique s'applique à des échelles plus grandes. Smolin résuma son idée dans La vie du Cosmos. La théorie présume que l'effondrement de trous noirs cause l'émergence de nouveaux univers de l'« autre côté » dont les constantes fondamentales (vitesse de la lumière, mur de Plank, etc.) peuvent différer légèrement de celles des trous noirs géniteurs. Chaque univers donne ainsi naissance à autant d'univers qu'il possède de trous noirs et certains univers peuvent mourir par mort thermique faute de constantes cosmologiques adéquates avant de donner une descendance. Ainsi, la théorie contient les idées évolutionnaires de reproduction et mutation des univers ainsi que de sélection naturelle. Pour Smolin, les univers les plus féconds, c'est-à-dire susceptibles de produire le plus de "bébé-univers", sont les univers riches en carbone et en oxygène, soit par ailleurs des univers susceptibles d'abriter la vie telle que nous la connaissons. Une telle théorie est une réponse au principe anthropique fort. (fr)
