Why is variation beneficial to the species but not necessarily for the indevidual?

Many of the varities are pre-adaptions which have no immediate benefits to the individuals. However, they remain in the population. whenever, environment under goes a drastic change,the pre-adaptations in some members of the population allow the later to survive, grow in its former size. therefore, it is not necessary that variations are beneficial to individuals developing them but can prove useful to the species.

∙ 13y agoBecause species evolve and natural selection selects the variants against the background of the immediate environment. Too bad for the variant that can not be reproductively successful in that environment as he is selected out.

∙ 9y agoSome variations produce traits that are just not useful. For example, if a new trait produced one short leg, this would mean that the human would have a great disadvantage. Even though there are treatments for this now, the treatments were not around hundreds of years ago. That person would be easy prey for an animal.

What are advantages of variation?
Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.
How does genetic variation prevent extinction of a species?
The genetic variation enable a particular species to withstand the adversities of Nature by way of selection on the basis of the principle of survival of the fittest.
Discribe what biodiversity means?
Biodiversity means the degree of variation of life. Some examples would be genetic variation in a species or ecosystem variation in a planet.
How does variation ensure that a species to survive?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Why is sexual reproduction preferable to a species?
It promotes genetic variation.
How is genetic variation related to species chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.
How is genetic variation related to a species's chances of becoming extinct?
Little or no variation could lead to failure to adapt to changing conditions. Too much variation would prevent the species from passing on beneficial traits because they would change too rapidly.

When do you think cloning is not beneficial?
When there is no variation at all, can you imagine all people are just the same. and also when there is an epidemic , since all of the cloned species is the same, all species may died and resulted in extinction.
What are specific examples of variation within a species?
Human species, as in the variation in height.
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.
Why genetic variation is of to benefit to a population?
It can provide resistance to diseases or other beneficial characteristics. -variation in more competitive species than our own can result in natural selection that is better focused to the specific environment: there is a bigger range of characteristics, so the best traits allow those members to survive longer and therefore mate more. This allows the species overall to constantly reproduce the beneficial traits and flourish.

What is a variation that can help an organism survive?
A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
Why all mutation are not necessarily harmful?
Mutations are changes in DNA. Most are neutral or beneficial. Mutations have allowed animals to adapt to new environments and new species to evolve.
Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new species.
Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
