Why is it important that variation exists within populations of a species?

Without variation there is nothing to select for against the background of an immediate environment and thus no evolution as alleles, not selected for, would not change over time in this population of organisms.
Without variation the environment can change quickly and send your population to extinction if there were no variants that could meet this challenge.

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.
Why does meiosis exist?
Meiosis exists to ensure genetic variation between offspring. As long as the genes are being passed on, interchanged, and reselected, a species will remain adaptable.
What are six factors of macroevolution?
I'm not sure that there exists such a thing as "factors of macro-evolution". Macro-evolution is simply what happens when reproductively isolated populations continue to diverge as a result of micro-evolution. They drift apart genetically, behaviourally and morphologically, so that the differences between them become greater and greater. The mechanisms that cause this are reproductive variation and differential reproductive success, the principal mechanisms of evolution.
Why does some genetic variation exist in members of the same species?
this is because the DNA of a species must be similar or else the species would look and act entirely different. DNA controls body structure and function, so if it is similar between organisms in the same species, they must look very similar and have some of the same natural instincts.
What is an extinct organism?
A species which no longer exists on planet earth because they all died for some reason or another. The dodo is an extinct organism.
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.
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.

When no living members of a species exists the species .?
when there are no living members of a species the species is said to be "extinct".
The genetic variation that exists in nature is enough to satisfy the needs of breeders?
TRue
Is genetic variation the exists in nature is enough to satisfy the needs of breeders?
Yes...
Define Extinct Species?
An extinct species is a species of organisms which no longer exists on the planet or has ceased to exist. ORAn extinct species is a species that has completely disappeared from the planet i.e. a single living specimen of which, neither male nor female, exists on earth.
Which of these is true of an extinct species?
It no longer exists on the planet
Where do species that no longer exists in the wild but is protected by humans?
on an island
What pigeon species no longer exists in the wild?
the passenger pigeon
The only species of hominid that still exists today?
humans
