Natural Selection Explanation
A species is a group of individuals that produces fertile offspring.
A population is a group of the same organisms or species.
The main source of genetic variation is meiosis. Within meiosis, fertilization occurs and creates variation. Within meiosis, although it is rare, mutations happen which can be also a source of variation. Gene flow, the movement of genes within multiple populations is another source of variation as well. Variation plays the role of making different traits in populations to lead to favorable and non-favorable traits to the environment which natural selection and selective pressure acts upon in the process of evolution. Variation is important
