In the case of genetic variation, the genes of the organisms or the individuals changes within a population. Gene alleles define distinct traits that can be transferred on from parents to offsprings. Gene variation is very necessary for the process of natural selection. The genetic variation that occurs in a population can happen by chance, but in the case of natural selection it does not.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
