Selection

page 1
natural selection
differential survival and reproduction of individuals in nature due to differences in phenotype; a key mechanism of evolution
cloning
thumb|upright=1.35|Many organisms, including aspen trees, reproduce by cloning, often creating large groups of organisms with the same [[DNA. One example depicted here is quaking aspen.]]
artificial selection
process by which humans use animal and plant breeding to selectively develop particular phenotypic traits
gene pool
set of all genes in a population
kin selection
the evolutionary strategy that favours the reproductive success of an organism's relatives, even at a cost to the organism's own survival and reproduction
r/K selection theory
ecological theory concerning the selection of life history traits
group selection
proposed mechanism of evolution
sex ratio
ratio of males to females in a population
Baldwin effect
effect of learned behavior on evolution
handicap principle
hypothesis in evolutionary biology
Directional selection
type of genetic selection favoring one extreme phenotype
Stabilizing selection
type of selection in evolution where a trait stabilizes around the average value
domesticated silver fox
domesticated form of the red fox
gene-centered view of evolution
since heritable information is passed from generation to generation almost exclusively by DNA, natural selection and evolution are best considered from the perspective of genes
Disruptive selection
natural selection for extreme trait values over intermediate ones
maladaptation
In evolution, a maladaptation () is a trait that is (or has become) more harmful than helpful, in contrast with an adaptation, which is more helpful than harmful. All organisms, from bacteria to humans, display maladaptive and adaptive traits. Like adaptation, maladaptation may be viewed as occurring over geological time, or within the lifetime of one individual or a group.
Genetic assimilation
Mechanism which genetically encodes phenotypes through evolutionary processes
selfish DNA
genetic material that promotes its own transmission
green-beard effect
hypothesis for altruism in evolutionary biology
balancing selection
any biological selection process that maintains genetic variation in the population
fitness landscape
model used to visualise relationship between genotypes and reproductive success
purifying selection
selective removal of alleles that are deleterious
frequency-dependent selection
biological selection that depends on the abundance of each phenotype in the population
genetic hitchhiking
incidental selection of non-harmful genes which are close to a beneficial gene on the same DNA chain
koinophilia
thumb|300px|This Leucism|leucistic Indian peacock, Pavo cristatus, is unlikely to find a mate and reproduce in a natural setting due to its unusual coloration. However, its striking colour is appreciated by humans, and may be included in artificial [[selective breeding to produce more individuals with the leucistic phenotype.]]
heterozygote advantage
biological selection in which heterozygotes are fitter than homozygotes for either allele
peppered moth evolution
significance of the peppered moth in evolutionary biology
selective sweep
genetic process
negative selection
aversion to the success of one's subordinates
Intragenomic conflict
Differential transmission of genes residing in the same genome
Organisms at high altitude
organisms capable of living at high altitudes
Pithecometra principle
term
Cultural group selection
Model of cultural evolution
Homo consumericus
mock Latin phrase referring to a consumerist society
