Apopulation of organisms will not evolve if the population lives in a habitat without competing species present the population size is large all individual variation is due only to environmental factors the environment is changing at a relatively slow rate submitmy answersgive up

The correct answer is all individual variation is due only to environmental factors.

Variations are necessary for changes, or evolution to occur. The basis of natural selection, which is the mechanism of evolution, is genetic variation. Within a given population, there is genetic variation that may or may not make an individual more adapted to the environment (or changes in the environment). A species with a great deal of genetic variability is more likely to survive in a changing environment.
