If all the members of a species were 100% identical (no variation) natural selection would have no effect. Members of such a species would die totally randomly with no influence from the selection pressure, so no natural selection could happen.

∙ 14y agoNatural selection (the mechanism of evolution) only works if there is genetic variation between individuals.
If all individuals were genetically identical there would be no way to select between them.
If individuals were genetically identical, but varied because of environmental factors, evoultion would still not occur because any useful variations could not be inherited by the offspring.
So, in the absence of genetic variation, natural selection cannot take place and so adaptive evolution cannot occur.

if there were no mutations there will only be probably gasses and water and land

Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
Write an original definition for genetic variation?
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
Why is variation beneficial to a population that is undergoing change?
Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.
Why is low genetic variation a problem?
Low Genetic variationis the raw material of evolution. Without genetic variation, a population cannot evolve in response to changing environmental variables and, as a result, may face an increased risk of extinction.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Why must a population have a genetic variation in order for natural selection to occur?
Without variation there is nothing to select from.
Can natural selection occur without variation in a population?
no there is no genetic variation for natural selection to act upon
What happens to a population when genetic variation decreases?
Less sex mutation and changes in DNA, I think?
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.
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
Write an original definition for genetic variation?
The genetic variation of a population is a measure of how much individuals in a population differ genetically.
What is the primary original source of genetic variation in a population?
Go to the link below, it has a lot of information on variation in population.
How large should the sample be to be large enough?
Span the full spectrum of a population's genetic variation. <apex> Reflects the genetic variation of a population...
Why is variation beneficial to a population that is undergoing change?
Yes, it is. If there is variation in a populations, and a sudden catastrophic event occurs, there is more of a chance that some of the individuals in the population will survive, and the population will not die out.
What causes variation of traits in a population?
the enviroment.
What is decontinuous variation?
Variation within a population in which few or no intermediate phenotypes fall between the extremes.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
