Mutations. These have quite a few different causes.
Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.
Independent assortment of chromosomes, crossing over and Random fetiliztion
mutation
Yes, mutations are a significant source of genetic variation as they introduce new genetic changes that can lead to differences in traits among individuals within a population.
Mutations are considered a source of heritable variation in organisms because they are changes in the DNA sequence that can be passed down from one generation to the next. These changes can lead to differences in traits and characteristics, allowing for genetic diversity within a population.
Mutations create changes in the genetic code. There are different types of mutations and vary in degree of harm or even benefit to the organism. If the mutation happens to be beneficial to the organism, then it can be passed down to its offspring and thus this leads to genetic variation in the population.

Human recombination is a significant source of genetic variation.
Independent assortment of chromosomes, crossing over and Random fetiliztion
Migration of individuals into or out of a population provides a source of genetic variation. This movement introduces new genes into the gene pool, increasing diversity within the population.

No, natural selection works on that genetic variation presented to it.
Genetic variation, which can lead to evoloution, and then potentially a new species.
Basic source of variation in all organisms is mutation .
What is a source of genetic variation that involves the swapping of sections of chromosomes during meiosis.?
