Natural Selection is a hybrid FPS/RTS that pits Marines against Aliens ("the Kharaa"), played primarily in the first-person perspective, within the confines of large atmospheric maps of spaceships or space stations, which have been invaded by the Kharaa. There are two game modes in Natural Selection: Classic and Combat.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype.It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
In what has occasionally been seen as a prefiguration of a concept of natural selection, Empedocles accepted the spontaneous generation of life, but held that different forms, made up of differing combinations of parts, spontaneously arose as though by trial and error: successful combinations formed the individuals present in the observer's ...
Dawkins builds upon George C. Williams's book Adaptation and Natural Selection (1966), which argued that altruism is not based upon group benefit per se, [4] but results from selection that occurs "at the level of the gene mediated by the phenotype" [5] and that any selection at the group level occurred only under rare circumstances.

Natural Selection 2 is a multiplayer video game which combines first-person shooter and real-time strategy rules. It is set in a science fiction universe in which a human team fights an alien team for control of resources and territory in large and elaborate indoor facilities. [1] It is the sequel to Natural Selection.
In addition, selection mechanisms are also used to choose candidate solutions (individuals) for the next generation. The biological model is natural selection. Retaining the best individual(s) of one generation unchanged in the next generation is called elitism or elitist selection. It is a successful (slight) variant of the general process of ...
The article was the first announcement of the Darwin–Wallace theory of evolution by natural selection; and appeared in print on 20 August 1858. The presentation of the papers spurred Darwin to write a condensed "abstract" of his "big book", Natural Selection. This was published in November 1859 as On the Origin of Species.
In natural selection, negative selection [1] or purifying selection is the selective removal of alleles that are deleterious. This can result in stabilising selection through the purging of deleterious genetic polymorphisms that arise through random mutations.
