Genetic variation that can be acted on by environmental pressure. Reproductive population that results in more organisms than can be supported by the ecosystem resulting in competition for limited resources, the ability of the organism to transmit genetic information to the next generation.
Heritability, Variability, and Selection are necessary to the process of natural selection.
- selection
- variability
- heritability
1. variation
2. heritability
3. differential mortality
1. different breeding 2. evolution 3.adaptation
The characteristic within the population that causes natural selection to occur is that individuals within a given population are not all identical because they vary. The other characteristic that causes natural selection to occur is that some variants are better than the others.
when there is competition
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.
1) Natural Selection 2) Climate changes 3) Geographical events 4) Radiations of organism into new habitats 5) Changes in ecosystem 6) Changes in continental position Above are mechanisms of selection, the environment, basically. Mechanisms of evolution are; mutation, gene flow. genetic drift and most importantly for adaptive changes, natural selection

Generally and simply, mutation, genetic variation and natural selection.
when there is competition
Mutation cannot occur
There are three types of selections. The three types of selections include: disruptive selection, natural selection, and directional selection.
