How can natural selection and isolation and genetic variation result in the development of a new species?

Yes but only closely related species. If you isolated some canaries for years you could come up with a sub species of canary. but no matter how long the animals were isolated they would still be birds. they would not change into a species other than a bird species even if given millions of years.

What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
How does genetic variation and environmental factors affect evolution by natural selection?
de
What resulted from a genetic variation that was favored by natural selection?
the long neck of a giraffe
Which of the following resulted from a genetic variation that was favored by natural selection?
The Long Neck of a Giraffe .
What where the 3 steps that lead to the formation to new species according to the theory of natural selection?
Generally and simply, mutation, genetic variation and natural selection.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
What do stabilization selection and disruptive selection have in common?
They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Do chnages in timing of genetic control during embryonic development contribute to the variation involved in natural selection?
no
What characteristic within populations cause natural selection to occur?
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
What do stabilizing selection directional selection have in common?
They both decrease genetic variation .
Cows that give more milk than other cows are an example of?
Natural variation, natural selection, artificial selection, genetic engineering, etc.
Which type of selection tends to increase genetic variation?
Natural Selection.
What is the signifiance of the genetic variation and natural selection?
genetic variation (from any of several sources) provides options to try.natural selection determines which of those options help the population most.
What id genetic variation?
Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
