How is natural selection important?
Natural selection is important because it changes the way we cope(live) in our enviornment.
Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.
How evolution by natural selection brings about changes in a species?

Today SCIENTISTs Explain natural selection in terms of changes in?
genes
Is artificial selection or selective breeding a good analogy for the selection that occurs in nature?
It is possible to have artificial selection in nature because of naturally occurring changes in the environment. These changes can greatly modify the organisms in question.
How do alleles influence natural selection?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
How does natural selection predict a gradualistic mode of evolution?
Gradualism isn't a prediction of natural selection, but of our understanding the mechanisms that produce reproductive variation. Natural selection makes predictions about allele frequencies in populations and reproductive fitness.
How is natural selection important?
Natural selection is important because it changes the way we cope(live) in our enviornment.
What exactly does the concept of microevolution mean?
Microevolution is the changes in allele frequencies due to mutation, natural or artificial selection, gene flow, and genetic drift. These changes occur over a long period of time within a given population.
Is eviromenntal changes drive reprodution a natural selection?
Environment IS natural selection, so a change in environment is a change in selection pressure.
Are new alleles made by natural selection?
No - natural selection does not create new alleles. Variation in alleles needs to exist in the population in order for natural selection to occur. Natural selection will involve the change in allele frequencies over time, but it does not create new alleles. New alleles are the result of mutations.
What will produce adaptive changes in populations?
Natural selection
Can natural selection act upon body shape?
Yes, that would be called the Homologous structure, and that changes in natural selection.

Are changes in allelic frequency driven by natural selection?
False
What causes the allele frequencies to changes?
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.
What changes in the gene pool result in adaptation to the environment?
Natural selection
