Evolutionary biology. Fitness (often denoted w {\displaystyle w} or Ï in population genetics models) is the quantitative representation of natural and sexual selection within evolutionary biology. It can be defined either with respect to a genotype or to a phenotype in a given environment.
Best Answer: 1. Evolution is defined as the change in the allele frequency in a population. Or in simpler terms, the change in the heritable traits in a population (such as a species) over time. Or in even simpler terms ...*evolution is change* (but change in a *species* over time, not an individual. However, there is also something called the theory of evolution (or TOE).irst evolution itself is not a theory, the theory of evolution for the development of species is a theory. Second, a theory means that it is an explanation. It has nothing to do with whether is has been proven. Nothing can be proven in science by definition.
