Fitness to a biologist means ' reproductive fitness. ' The variant organism that survives against the immediate environment and leaves more descendants that the other organisms of his population is fit. These descendant's this organism leaves change the allele frequency of the populations gene pool and this is the definition of evolution.

The environment is the natural selector.
By science
It is, in fact, evolution (shifts in the frequencies of traits in populations) that causes adaptation (when these shifts lead to increased fitness).
Evolution is the gradual change of a population in response to changes in the environment. Evolution does not occur in individuals, it can only occur when a mutation is added to a population or a certain gene is selected for. Evolution occurs because the fittest individuals who pass their genes on the most are the ones best suited for the environment. Those that don't survive don't pass on their traits. It is important to note that fitness described in survival of the fittest pertains to reproductive fitness, not physical fitness.
Fitness is generally measured in average number of fertile offspring.

The best way to find out about the reviews for Fitness evolution would be to go online and visit any Fitness website. Jenny Craig or Weight Watchers are some good websites.

The reviews on Fitness Evolution are very poor. There has been many reports of malfunctions. Many people have found it easier to just look at a different machine.

Diversity increases the chance of human survival. When a species is more diverse there is a larger chance of the population surviving an epidemic or such that might relate to biological variations in DNA or variations in "fitness" (biological variations). based on Darwin's Theories and Evolution
