Does the population or organism go through natural selection?
No, populations of organisms evolve, individuals are naturally selected.
Which statement is more accurate to scientist the evolution of a single individual organism or the evolution of a whole species?
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
What does evolution mean in science?
Evolution is the gradual change of a population in response to changes in the environment. Evolution does not occur in individuals, it can only occur when a mutation is added to a population or a certain gene is selected for. Evolution occurs because the fittest individuals who pass their genes on the most are the ones best suited for the environment. Those that don't survive don't pass on their traits. It is important to note that fitness described in survival of the fittest pertains to reproductive fitness, not physical fitness.
What is the advantage of an adaptation to a species?
So the species can reproduce and survive.WRONG!!Adaptions are of no use to a species as adaptions are the result of adaptive change which is the purview of natural selection and only INDIVIDUALS are selected. The adaptions of individuals help them to survive and, more importantly, have reproductive success over conspecifics in the immediate environment.Then alleles are changed over time in the population and evolution occurs, but the adaption is an individual process that leads to wide allele change and progeny having the adaption.Remember, individuals are selected while populations evolve.
Does natural selection operate only on an individual over many generations?
The answer below is partly right, but natural selection actually does not act on an individual. As stated below, individuals within a population of a given species are selected based on physical trains which benefit, but not for the survival of the animal itself. It is important to note that in Darwin's Theory of Natural Selection, environmental change does not create new alleles but rather select from the gene pool of a population that has the allele which would benifit in a given condition. Thus, natural selection act on a population and its gene pool rather than the individuals. Yes. According to Charles Darwin's theory of natural selection, individuals within a population of a given species are "selected" based on physical traits which benefit the survival of the animal. However, they are only "selected" thanks to the individuals that die, because they are not physically suited for survival as well as the others. Natural selection acts directly only on those to die, because it is technically the only physical "act" or determining factor that demonstrates Darwin's theory. All the rest simply has to do with the animals left over, which simply breed as usual inevitably creating better and better animals, while natural selection picks off all those that are not quite good enough.
The smallest unit of evolution is the population?
Yes, populations evolve. Individuals/genes are selected.
Does the population or organism go through natural selection?
No, populations of organisms evolve, individuals are naturally selected.

Why are fatal diseases not naturally selected out of a population?
Due to interbreeding

What characteristic defined individuals that survive according to Darwin's theory?
That are reproductively successful. The individual dies; populations evolve. Individuals are naturally selected.
How does evolution and natural selection differ?
Evolution is the change in allele frequency over time in a population of organisms. This change over time can be just recombination, genetic drift or gene flow. Natural selection can cause evolution, but individuals are selected while populations evolve, so only a selected person's progeny would be part of that population's evolution. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms. So, individuals who have beneficial variations, in their immediate environment, can be selected and will pass on those variations, in their germ line, to progeny who will insert their alleles into the populations gene pool where allele frequency may change; evolution. This is soo stupid don't listen to this crap. I don't understand why all these ediots post this
When types of selection occurs when individuals in a population with the intermediate phenotype are selected for?
Stabilizing selection occurs when organisms with intermediate phenotypes are selected for.
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.
What is population sampling?
Population sampling is the process in which a group of individuals are selected to represent a population for the purpose of statistical analysis. Population sampling allows the analyzers to learn about a population without studying every individual in it.
