Differential reproductive success is the effect that produces natural selection. Natural selection is the result of some variants within a population having more reproductive success, producing (on average) more offspring, than other variants, thereby increasing their stake in the population gene pool.
An early catchphrase coined to indicate this process is survival of the fittest. This catchphrase is wrong - or at least misleading. It suggests to the layman that natural selection is about the less-fit dying, while the fitter survive. But as explained above, it is not as simple as that: it is about the less-fit fading from the population, whether through death or because they are out-reproduced by the fitter variants. In this context 'fitness' does not mean stronger, or faster, or smarter or even healthier: it means having a larger average number of offspring.

What is the importance of reproduction in natural selection?
Everything! Survival is the race, but reproductive success is the finish line. Remember; individuals die, populations evolve.
What benefit does the plant receive?
The assurance of reproductive success.
What is the effect of differntial reproduction over time?
Overproduction of offspring and more changes like adaptation for survival.
What is natural selection like?
Natural selection is the nonrandom survival and reproductive success of randomly varying organisms selected against the immediate environment. Like that. Remember this little explanation and you have natural selection down pat
Did success fame affect the life of Pasteur?
did louis pasteur success affect his life
What is the primary reason why organisms develop adaptations?
To enhance their survival and reproductive success
What is natural selection and how does natural selection evolution?
A simplified explanation. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms who by this reproductive success change the allele frequency over time in populations of organisms, which is evolution.
How is mimicry a adaptation?
Anything that leads to survival and reproductive success is, generally, an intrinsic adaption. If a butterfly were to mimic another butterfly that was poison to it's predators then those self same predators would tend to leave the non-poison butterfly alone as well as the poison butterfly thus leading to survival and reproductive success for the mimic.
What is the importance of reproduction in natural selection?
Everything! Survival is the race, but reproductive success is the finish line. Remember; individuals die, populations evolve.
What is natural selection also known as?
Survival of the fittest
How do differences between individuals and environments affect natural selection?
Differences between individuals may affect differences in their average reproductive success, causing the variant traits of individuals that have greater reproductive success (fitness) to become more prevalent in a given environment than rival traits. As environments change, so may the traits that have a reproductive advantage change. This is natural selection.
What is struggle to survive in evolution?
The "struggle to survive", "survival of the fittest" and "natural selection" are all phrases to indicate the main guiding mechanism of evolution: differential reproductive success.
What is the gist of Charles Darwin's theory of evolution?
Theory of evolution by natural selection. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. That simple.
Is the reproductive system necessary for survival?
It is necessary for species survival as a whole. Although reproduction generates an individual, the individual's own reproductive system is not necessary for its survival; although loss or damage to the organs may have deleterious effects beyond loss of breeding ability.
Why is reproductive essential?
to ensure the survival of a species.
Why is the female reproductive is fit to male reproductive?
To encourage and ensure copulation and survival of the species.
Which of these humans is the fittest as far as natural selection is concerned?
The human with the greatest reproductive success personally, or have siblings with great reproductive success,
