What does Survival of the fittest and natural selection mean?
Survival of the fittest is a not quite accurate phrase for natural selection. Natural selection is, The non-random survival and reproductive success of randomly varying organisms.
What is the difference between charls Darwin's theory of natural selection and the social theory of survival of the fittest?
I'm not sure. The topic of the Charles Darwin's Theory of natural selection and the theory of survival of the fittest go hand in hand. I can't find a difference really besides the obvious. xD. They both have something to do with that adaptions.Charles Darwin's Theory is mostly like, saying that things can adapt over a large period of time to solve problems. [Like the finches with big beaks could break big nuts while the finches with the smaller beaks starved and only the finches with big beaks survived and reproduced].Also, that some animals, over time, probably came from a similar animal, but just adapted to its surroundings.The Theory of "Survival of the Fittest" is mainly about that animals with successful adaptations are the ones staying there. Like the Dodos. They didn't survive since they were like, dumb, flight-less birds. So, they went extinct.But I know that the survival of the fittest amd the theory of natual selection are the same and both are from Charle Darwin..Welll that's what I know from my sir..I am anti-TENTS..read between the lines of THIS> )
How did artificial selection influence Darwins thinking?
Maybe u should actually answer because i'm to tupid to know the answer/ The artificial selection although controlled by the choices of humans created novelty in the races. During natural selection the environment is responsible for selecting the best types. Darwin's ideas of natural selection were based on the fact of struggle for existence and survival of the fittest. Thus by artificial selection some of the races have been developed which can sustain the present environmental conditions. this has contributed to his ideas.
Why is variation so important to natural selection?
Without variation natural selection could not select among members of a population that were all the same. How would these organisms become reproductively successful if they did not vary in the traits that allowed some to survive and reproduce, while others don't while changing the allele frequency of the population, which is the definition of evolution?
What does natural selection act upon?
Natural Selection is driven by random mutations and sexual reproduction. Organisms produce more offspring than can survive. These offspring compete for resources for food and water and who can aviod stuff such as predators and disease. Sexual Reproduction allows a population to have variation. If all of a population was the same, then it could easily die out if it had a adaptation that decreased its chance of survival. With sexual reproduction, all of a population has some sort of variation. Random Mutations allow organisms to gain new adaptions to help them survive in their environment. Together, Random mutations and sexual reproduction allow organisms that can survive in their environment survive and pass on their genes to their offspring.
What does Survival of the fittest and natural selection mean?
Survival of the fittest is a not quite accurate phrase for natural selection. Natural selection is, The non-random survival and reproductive success of randomly varying organisms.
Organisms with traits well-suited to their environments survive and reproduce at a greater rate than less well adapted organisms in the same environment is called?
Natural Selection. Survival of the fittest. The organisms with the best traits are able to survive and reproduce.
Are evolution and survial of the fittest the same thing?
Evolution is the changing of a species over generations. Survival of the fittest, or natural selection, is where individual organisms who are fitted to survive in their environment live, and those who aren't don't survive. Natural selection affects evolution by keeping some genes alive and losing some.
What does Darwin mean by survival of the fittest?
It should be noted that it wasn't Darwin who coined the phrase "survival of the fittest", and that biologists do not generally use the phrase, as it is an inaccurate description of natural selection. Natural selection is the mechanism by which populations adapt to changing circumstances, or the mechanism that filters the genetic drift of populations to better fit existing circumstances. Natural selection is the term used to describe the differential reproduction of variant alleles. Alleles that affect the reproductive capabilities of the organism that bears them positively will increase their frequency in the population gene pool. Alleles that affect their own reproduction negatively will decrease their frequency.
How does natural selection determine the differential survival of groups of organisms?
In a sense, one might say that this is the case. But in a more direct sense, natural selection determines which organisms do not get to procreate (as much). Natural selection is therefore more a limiting phenomenon than an enabling one.
What role does natural selection play in evolution?
Survival of the fittest. Only the strongest/healthiest of a species survive and reproduce. This means that their genes are passed along to the next generation resulting in more animals with the same health/strength traits. Thus weaker animals slowly die out.
What causes variation of animals in the same species?
in gene pool, it comes from a random mutation
Why are there not super-strong lions if evolution allows only for survival of the fittest?
This is equivocation between the word "stronger" in terms of "more adaptable to the environment" and "stronger" as in "has more physical force". A physically weaker lion may be able to endure a harsh drought more effectively than a physically stronger lion, so natural selection would select for the weaker lion because it will have children. Additionally, natural selection and evolution are the same thing. Evolution is the long-term change in populations driven by natural selection on individual organisms.
How are artificial selection and natural selection similar?
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.

What is the process that makes it more likely that organisms with the best characteristics for survival in an environment will survive reproduce and pass on genetic traits?
When organisms with favorable variations live, reproduce, and pass on their favorable traits, this is called natural selection. This is also characterized by the phrase "survival of the fittest" in the evolutionary process. However, this is not always the case. Many times the survival of entire species depends upon outside influences such as a devastating meteor impact, or an earthquake, or any one of the innumerable environmental influences that determine whether an organism lives or dies. Also, one must consider the environmental influences such as droughts or storms and even temperature. Though not in all cases, the genome with its many checks and balances could be the determining factor. For instance, temperature of the outside air may trigger a genome moderation that may or may not be seen in the healthiest specimens while being retained or influenced by the very sickness or vigor of the organism involved, For example, virus survive by introducing themselves to the host and the genome may or may not be influenced into modification, an occurrence that may or may not occur normally in a pristine or hearty individual. Timing is also important. For example, undersea eruptions may deliver compounds needed for modification even though the creature or organism may never encounter such except in extreme instances. Also, as in the case of the human species, the longevity of organs such as the heart and lungs tend to erode with time, mostly by continued exertion. All organisms tend to show that with longevity organs tend to just wear out and that is all there is to it. All in all, survival of the fittest certainly gives an ecological advantage but this line of departure is somewhat misleading. One must remember that all organisms are made of the same atoms and the various factors asserting influence on these atoms is consistent between the hearty and robust and the sickly and weak.
