How is variation beneficial to a population of organisms?
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
What does evolution mean scientifically?
In the science, evolution means change over time. These changes are selected by the environment. What genes (traits) that will allow a species to survive will be passed on to the next generations.
What is the relationship between overproduction of offspring and natural selection?
Overproduction of offspring means overproduction of variants that can not all live on the resources in their immediate environment. Thus those organisms who can survive to be reproductively successful in a limited resource environment are naturally selected for and pass these traits on to their offspring.
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.
What is the scientific definition of selection?
Selection, in terms of evolutions, is the process by which advantageous traits in a population are passed on by the carriers who are able to survive and reproduce due to the advantage that this trait gives them. Less advantageous traits are thus not "selected" and passed on to the next generation because these individuals are less "fit" for the environment and are out-competed by the individuals with the more advantageous traits. Therefore, only the traits that make an organism most "fit" for the environment are passed on.
Traits selected by humans instead of the environment?
Artificial selection.
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.

Does an animal's environment affect or does it not affect its adaptation?
This is the fundamental premise of the Theory of Evolution by Natural Selection; the environment has a fundamental impact on the adaptations and evolution of organisms. The environment "selects" for those specimens that survive to have more offspring. Those animals that cannot survive are selected against.
How can a stressful environment alter the standard r-selection and k-selection?
1. What is the difference between r-selected and k-selected organism? Which strategy would you expect to be more prevalent in unpredictable environments (high stochastic variation in conditions)?
What characteristics must population first have for nautral selection to occur?
Individuals are selected, but in the population of organisms there are many variations, some better at survival and reproduction than others, and against the immediate environment, what natural selection really is, these beneficial variations will be selected.
How is variation beneficial to a population of organisms?
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
Why do some environments have more types of organisms than others?
Natural selection "selects" organisms that are best suited for each environment. Those that are not fit for the environment are selected against until they migrate or become extinct all together.

Why is Planting of trees in Pakistan is done in selected periods?
the planting of trees in pakistan is done in selective period because the trees are dependent on the external environment and weather
What is essnetial to evolution?
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
What mutation has the greatest effect?
The mutation that has the greatest effect is one that is not only beneficial but that is heavily selected for by the environment. Ideally dominant as it will effect the population more rapidly than a recessive trait. Only traits that are selected for or against in a population change the frequency of the occurance of the alleles in the population.
