Survival games are almost always playable as a single-player game, but many games have been designed to be played in multiplayer, with game servers hosting the persistent world that players can connect to. The open-ended nature of these games encourages players to work together to survive against the elements and other threats that the game may ...
Instead, survival of an organism depends on the differences of each individual organism, or "traits," that aid or hinder survival and reproduction. Well-adapted individuals are likely to leave more offspring than their less well-adapted competitors. Traits that hinder survival and reproduction would disappear over generations.
Note that somatic mutations are not heritable, they are only a source of developmental variation. Studies done on Drosophila melanogaster have shown that mutation accumulation drives the combination of alleles which have "age-specific additive effects" that cause a decline in stress response and ultimately an age-related decline in fitness.

Note: George Price, one of the early mathematical modellers of both altruism and spite, found this equivalence particularly disturbing at an emotional level. [21] Selfishness is the base criteria of all strategic choice from a game theory perspective – strategies not aimed at self-survival and self-replication are not long for any game ...
This definition is based on that of “biome,” the biotic and abiotic factors of given environments. Others in the field limit the definition of microbiome to the collection of genes and genomes of members of a microbiota. It is argued that this is the definition of metagenome, which combined with the environment constitutes the microbiome.
Microbial genetics can focus on Charles Darwin's work and scientists have continued to study his work and theories by the use of microbes. [7] Specifically, Darwin's theory of natural selection is a source used.
A proposed definition for both terms as the "physical totality of all traits of an organism or of one of its subsystems" was put forth by Mahner and Kary in 1997, who argue that although scientists tend to intuitively use these and related terms in a manner that does not impede research, the terms are not well defined and usage of the terms is ...
Microbial ecology (or environmental microbiology) is the ecology of microorganisms: their relationship with one another and with their environment. It concerns the three major domains of life— Eukaryota , Archaea , and Bacteria —as well as viruses . [ 2 ]
