How does a characteristic which helps an animal to live longer will generally tend to become more common in the population as a result of evolution by natural selection?

The trait, 'to live longer ', would only be selected for in individuals if it was reproductively successful. Then the alleles for living longer would be more frequently represented in the population of these animals.

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.
What relies upon evolution by natural selection?
it relies upon the population
Compare and contrast natural selection and evolution?
Natural selection is the most powerful driver of evolution and it is the only mechanism of evolution ( genetic drift and gene flow are two other mechanisms ) that leads to adaptive change. Natural selection is the nonrandom survival and reproductive success of of randomly varying organisms. Evolution is the change in allele frequency over time in a population of organisms.
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 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.
Which is more likely to be true natural selection or evolution?
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
Who the theory of evolution?
The generally accepted theory of evolution by natural selection was proposed by Charles Darwin
Who had the theory of evolution?
The generally accepted theory of evolution by natural selection was proposed by Charles Darwin
How do adaptations connect to evolution?
Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.
Why heritable characeristic which helps an animal to live longer will generally tend to become more common in the population as a result of evolution by natural selection?
These are called adaptations.
What relies upon evolution by natural selection?
it relies upon the population
Which force of evolution makes a population more alike?
Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
Do evolution stop?
No. Evolution is the change in allele frequency over time in a population of organisms. This may be the result of stabilizing selection, but is still evolution.
What can the theory of evolution by natural selection explain about a population?
How it can change in response to its enviroment
Is unit of evolution species or population?
Population is the unit of evolution. A population is defined as a group of organisms of a particular species that inhabits a particular area. Natural selection acts on traits within that population that are beneficial in the particular area. Another population of the same species may be under different selective pressures (as it is found in a different location), and natural selection may therefore act on different traits within that second population. The two populations, thus, may evolve differently. Therefore, the unit of evolution is the population, not species.
Generally evolution by natural selection occurs quite slowly over?
Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
