Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
It causes diseases
The four major causes of organic compounds found in living organisms are carbon, hydrogen, oxygen, and nitrogen. These elements are essential building blocks for proteins, carbohydrates, lipids, and nucleic acids, which are key components of living organisms.
Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.
Climate change can cause various effects. It causes living organisms to move from their natural habitat.
Having an ozone hole causes damage to the environment by increasing the exposure of living organisms to harmful ultraviolet (UV) radiation from the sun. This can lead to negative effects on human health, including skin cancer and cataracts, as well as damage to ecosystems and wildlife. Additionally, it can impact climate patterns and contribute to global warming.
Sexual reproduction causes variation in organisms because it involves the mixing of genetic material from two parents, resulting in offspring with a unique combination of genes. This variation is essential for the adaptation and evolution of species over time.

It harms them. It causes various fatal diseases on living organisms.
differential reproductive success caused by genetic variation is necessary for the process of natural selection.

it is caused when the variation is hit on the guitar
the variations in genes, genes of sexually reproducing organisms will vary due to crossing-over of genes, mutations, and adaptations. In asexually reproducing organisms genes will vary through adaptations and mutations.
Viruses are not considered living organisms but can cause disease. Prions that cause Bovine Spongiform Encephalopathy (Mad Cow disease, aka vCJD- variant Creutzfeld-Jakob disease when in humans) are not living organisms as they are just misfolded protein particles.
Mutation of the genetic code causes DNA variation in organisms. For example, during DNA replication, one nitrogen base may be substituted for another, or an extra base can be added, or a nitrogen base can be skipped. If any of these mutations occur during the formation of gametes (sex cells), then the offspring that receives the mutation may have a genetic disorder.
Climate change can cause various effects. It causes living organisms to move from their natural habitat.
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.
Without variation natural selection would have nothing to select from that would confer survivability and reproductive success. on the organisms being selected against the organisms conspecifics and the immediate environment. Mutation and sexual recombination provide the main sources of this variation that is needed to make selection work. Mutation is the variation presented that causes the real adaptive change that can lead to speciation.
