Both of the following are correct: They have extremely short generation times and large populations; They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer.
mutations
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.
Mutation.
Carbohydrates are the body's primary and immediate source of energy.
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
Mutations can be a source of genetic
The most important source of variability in bacteria is mutation.

Often in reproduction, broken chromosomes are formed by random natural factors. When these combine with other chromosomes, new characteristics can be formed which are different from the Natural Chromosomes.
Go to the link below, it has a lot of information on variation in population.
the mutation can be a sources of genetic variety.
It is a primary source.
Human recombination is a significant source of genetic variation.
A picture can indeed be a primary source.
it is a primary source
It is a primary source because it was taken at the time.
yes,a coin is a primary source
