In the genetic sense, it can't. Evolution really has one direction, and one direction only: forward. However, evolution may cause organisms to evolve traits that resemble traits of some of their precursors. For instance, whales are sea-mammals that descended from land-mammals, which in turn evolved from earlier aquatic organisms like fish. But due to the demands of their environment, whales evolved an overall morphology that resembles those of these earlier fish.

Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
What does natural selection lead to?
Natural selection leads to evolution by giving the organism that is best suited for the area to thrive. Thus those who not suited for the area die off and evolution moves forward.
What process in which organisims with traits well suited to an environment are more likely to survive and to produce offspring is?
natural selection
Is adaptation part of natural selection?
Adaptation is the result of natural selection.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
What is the relationship between evolution and natural selection?
Natural selection is one force that can lead to evolution.natural selection is one cause of evolution
Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection on a single-gene trait can lead to changes in allele frequencies for the alleles of that gene.
What is the relationship between adaptation and natural section?
Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

What will natural selection eventually lead to in a population?
Changes in morphology and behaviour.Speciation.Extinction.
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.
Why are variations in a species needed for natural selection to occur?
What would be selected if organisms did not have differences that lead to better survival and reproduction, or the opposite. That is all natural selection is.
Natural selection is the only mechanism of evolution that will lead to?
Adaptive change and speciation.
How do natural selection cloning and selective breeding lead to evolutionary change?
The only thing that causes evolution is Mutations due to forced natural selection of desired alleles.
Does natural selection lead to helpful or harmful variations that continue through the species?
HeLpful
What are the four processes that lead to evolution?
Mutation, Natural Selection, Migration, and Genetic Drift.
What are three ways that can lead to speciation?
by natural selection, genetic drift and geographical isolation
What does natural selection over long periods of time lead to?
Natural selection over long periods of time leads to a fitter and more reproductively successful group of organisms thus becoming more common in a population. It will lead to evolution.
