Cosmological natural selection
From EvoWiki
Cosmological natural selection is a term generally applied to Lee Smolin’s theory of Fecund universes.

Reproduction through black holes
According to this theory every time a Black hole forms in any universe within the Multiverse the matter within the Black hole emerges to form a new universe in a different region of space time.
Smolin theorizes that these new universes will have similar parameters to the parent universe but their parameters will be slightly altered or mutated. In a process analogous to Darwinian natural selection those universes best able to reproduce will predominate.
Other universes generation suggestions
Many ways of generating new universes are proposed. Current cosmological models suggest that the parameters are reset at random each time this happens. The exception is Fecund universes described above. If cosmologists can develop models where daughter universes resemble the parent universe in other cases Darwinian natural selection will apply there as well.
“The Descent of the Universe Smith (1990) and Smolin (1992) have independently suggested a mechanism for the evolution of universes by natural selection. They propose a multi-universe scenario in which each universe is the residue of an exploding black hole that was previously formed in another universe.
An individual universe is born with a certain set of physical parameters—its "genes." As it expands, new black holes are formed within. When these black holes eventually collapse, the genes of the parent universe get slightly scrambled by fluctuations that are expected in the state of high entropy inside a black hole. So when the descendant black hole explodes, it produces a new universe with a different set of physical parameters—similar but not exactly the same as its parent universe. (To my knowledge, no one has yet developed a sexual model for universe reproduction.)The Anthropic Coincidences: A Natural Explanation by Victor J. Stenger. “
Colliding Universes and possible sexual reproduction
The Ekpyrotic theory suggests that the state of our universe was radically changed when our universe collided with another universe in the 11th dimension. ”(…)nobody knows if the scale invariant spectrum will be destroyed by the big crunch, or even what happens when two branes collide.” [1] If cosmologists can develop models where after a collision one or both universes have the parameters of both ‘parent’ universes or have some of the parameters of both ‘parent’ universes this will be a model of possible sexual reproduction.
The daughter universes need not form directly after “genetic exchange” or exchange of parameters has taken place. Daughter universes may form through black holes or by other means at any later time. If the parent universe has exchanged parameters with another universe through a collision the 11th dimension or by other means daughter universes will share the parameters of both colliding universes, “ slightly scrambled”.
