How does a characteristic that contributes to few or no offspring not become more common as a result of evolution by natural selection?

The question answers itself: the characteristic is passed onto few or no offspring, and therefore will not spread throughout the population.

Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
6 Explain why evolution by natural selection can not occur if the variation in a characteristic does not contribute to differences in fitness?
If there is not reproductive fitness conveyed by a variant trait, then natural selection has nothing to select and nothing to promote into the populational gene pool.
How does natural variation affect evolution?
Natural selection (the driving force of evolution) is the selection of genetic variations by how they effect the organism's chances of survival or reproduction. If they diminish it's chances, the organism or it's immediate offspring die and the gene is gone. If the genetic variations increase it's chances, then it survives. Without genetic variations there can be no evolution. Natural selection is the selection (by environmental pressures) of those variations.
In evolution survival of the fittest refers to?
In evolution, natural selection is often called survival of the fittest.
How is mutation and natural selection similar?
Both establish that: 1. There are limited reproductive opportunities 2. Only those organisms with "favorable" traits will be allowed to reproduce and pass the traits onto their offspring The difference is that artificial selection involves human intervention
What are the criteria of success in terms of evolution by natural selection?
The fitness of a variant is expressed in terms of the average number of offspring.
What are some theories of evolution?
AnswerThe principal theory of evolution is the Theory of Evolution by Natural Selection, put forward by Charles Darwin in On the Origin of Species.Darwin's original theory has been refined , but it is still considered substantially true just as he described it.A subsidiary theory of evolution, that relies on the same processes as Darwin described, but explains aspects of species that Natural Selection does not fully explain, is the Theory of Evolution by Sexual Selection. This posits that, for example, females mate with males that they find most attractive. Therefore genetic lines that provide sexually attractive features in offspring are more likely to be passed on. It is also stated, that the preference for the sexually attractive characteristic can be passed on in the females, thus reinforcing the propensity to maintain the characteristic.
What was Darwin's greatest scientific contributes?
he proposed a theory about natural selection
What factors support evolution-?
As we currently understand it, evolution happens if: - There are populations of organisms reproducing with variation - Those variations are inherited by offspring - More offspring is produced than can comfortably subsist in the habitat - Offspring therefore compete with one another for resources and mating opportunities - Variant inherited traits affect their ability to compete.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
Why is the species rather than the individual considered to evolve?
Evolution is a gradual process that occurs through natural selection. Natural mutation results in some offspring.
How is natural selection and evolution linked?
Natural selection is one of the 'guiding' principles of evolution.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
When natural selection favors the intermediate version of a characteristic it is called what?
It is called evolution. After all, all characteristics, as far as evolution is concerned, are intermediate. They're all temporary variants, on their way to becoming something else.

When an animal is selected based on its offspring what is the selection method by?
when an animal is selected based on its offspring, the selection method is by what
How animals evovled?
Evolution is garnered by natural selection. Natural selection occurs when a mutation in a gene leads to a greater fitness in an individual(able to have more offspring). These individuals are better suited for their environment and thus survive more often and reproduce more making the gene more common. That evolution in a nutshell.
