What does it mean when Darwin saw that variation exists within a species?

When studying and proving the theory of evolution, Darwin notice that variations existed within species. Species includes organisms that are closely related and can mate to produce fertile offspring. Variation is a difference. Darwin noticed that there were more than one organism inside a species.

What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
What are specific examples of variation within a species?
Human species, as in the variation in height.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
What term describes changes that within species?
variation
How does variation within a species increases its chance to survive when the environment changes?
The differing traits provided by variation mean that at least some groups of the species may be better prepared to survive.
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.

How do you describe Darwin's theory of evolution by natural selection?
The natural production of variation within an animal species and the survival (and by implication breeding) of the fittest variants.
Does variation within the same species exist?
Of course, variation exists within individuals of the same species. This is because there are a small minority of genes which have multiple alleles in most species. In cases where a subset of the population is isolated from the rest of the population, a subspecies may develop which has particular unique characteristics but can still interbreed with the rest of the species.
What is a major cause of variation within species?
Variation of a species can come about in many ways, but mutation is the major cause of variation in a species.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Which process produces the most variation within a species?
Variations occurs in species due to the process of "Crossing over"
What term describes changes that within species?
variation
Why according to Darwin two different areas within same continent have different species?
Why according to Darwin two different areas within same continent have different species?
What causes variation within a species?
It has adaptations
How do the Grants data show that genetic variation is important in the survival of a species?
The Grants' work shows that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
