In a case like this, the unit of selection, sometimes called the “target” of selection, is the single organism, the individual deer, and the property being selected, swiftness, also lies at the organismic level, in that it is exhibited by the intact and whole deer, and not by either parts of deer, such as cells, or groups of deer, such as herds.

Retrotransposons are DNA sequences that generate copies of themselves that later insert themselves in the genome more or less randomly. For evolution to be driven by species selection, however, the patterns of differential persistence of species over geological time must be the result of selection for species-intrinsic properties rather than for properties of genes, cells, individuals, or populations of the species involved.

Below, undisputed cases of selection at the genic, cellular, individual, and group level are presented and discussed, starting with individual selection which is the most familiar type. The speed of the faster gazelle could be caused by a single gene, be polygenic, or be fully environmentally determined, but the unit of selection in this case is the individual since the speed of the gazelles that selection is evaluating, is a functional property of each individual gazelle, i.e., individual speed is the property being selected-for. That selection can operate at and above the level of species remains controversial among biologists. • Adaptations are common at the level of organisms.

Note, however, that in this case of selection it is the presence of predators what creates an opportunity for faster individual gazelles to be selected and for their speed to be selected-for, so that this presence is, in the deepest ultimate sense, the cause of the selection regime that is active. Williams and Dawkins, for instance, have treated the problem of the unit of selection together with that of the unit of heredity and of the unit of evolution, which does not help one in dissecting selection as a causal process that generates fitness differences. UOS is defined as unit of selection rarely. The unit of natural selection is individual since genes work at an individual level. 3. Compare an alternative formulation of Dawkins’ central question: When we say that an adaptation is “for the good of” something, what is that something?…I am suggesting that the appropriate “something,” the “unit of selection” in that sense, is the active germ-line replicator.

When a gazelle, for instance, has a trait that allows it to run faster than others and therefore to avoid predators more effectively so that ultimately it manages to stay alive longer and reproduce over more breeding seasons, the causation of the higher fitness of this gazelle can be accounted for fully only if one looks at how individual gazelles fare under predation so one can come to the conclusion that the faster gazelle's speed allows it to avoid predation better. Selection at the level of the organism can be described as Darwinism, and is well understood and considered common. And this focus on causation has indeed led the philosopher of biology Elliot Sober, to stress that causal explanations of the process of selection should be as central to the narratives describing natural selection as they are to any scientific narrative.

And indeed in natural systems such viruses display much lower virulence levels than do mutants of the same viruses that in laboratory culture readily outcompete non-virulent variants (or than do tick-transmitted viruses since ticks do bite dead rabbits). An allele is defined as a suite of genes that are required for constructing a specific structure or behavior; to the extent that genes are selected on the basis of their phenotypic results, natural selection cannot act on genetic units smaller than the allele.
