Fitness (often denoted or ω in population genetics models) is a quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be defined either with respect to a genotype or to ...
Herbert Spencer coined the phrase "survival of the fittest". " Survival of the fittest " [1] is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. In Darwinian terms, the phrase is best understood as ...
In evolutionary biology, inclusive fitness is one of two metrics of evolutionary success as defined by W. D. Hamilton in 1964: An individual's own child, who carries one half of the individual's genes, is defined as one offspring equivalent. A sibling's child, who will carry one-quarter of the individual's genes, is 1/2 offspring equivalent.
v. t. e. In evolutionary biology, fitness landscapes or adaptive landscapes (types of evolutionary landscapes) are used to visualize the relationship between genotypes and reproductive success. It is assumed that every genotype has a well-defined replication rate (often referred to as fitness ). This fitness is the "height" of the landscape.
In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness.

Kinesiology (from Ancient Greek κίνησις (kínēsis) 'movement', and -λογία -logía 'study of') is the scientific study of human body movement. Kinesiology addresses physiological, anatomical, biomechanical, pathological ...
Wikipedia:Contents/Health and fitness. Health is the level of functional or metabolic efficiency of a living organism. In humans, it is the ability of individuals or communities to adapt and self-manage when facing physical, mental, or social challenges. The most widely accepted definition of good health is that of the World Health Organization ...
Differential fitness. Differential fitness is the third of Darwin 's four postulates for natural selection. It states that survival and reproduction rates vary between individuals. Fitness differentials are widespread and detectable throughout nature. This fitness differential is visible in several ways, and it can be detected throughout nature.
