What provides the variation on which natural selection acts?
Variation is created when natural selection gives every surviving individual a new advantageous allele.
Variation develops because individuals deliberately change their alleles when the environment changes.
Variation exists only because individuals acquire different characteristics during their lifetimes.
Variation exists between individuals, partly because they have different alleles.
