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.

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?
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
What comes first mutation or natural selection?
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
What is the main difference between natural selection and genetic drift?
The main difference between natural selection and genetic drift is that natural selection involves the differential survival and reproduction of individuals based on their traits, leading to an increase in advantageous traits in a population over time. Genetic drift, on the other hand, is a random process that can lead to changes in allele frequencies in a population due to chance events, rather than selection pressure.
How has the natural selection harmed the ecosystem?
It hasn't. Natural selection is a key part of the ecosystem itself.
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.
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.
Does natural selection on single-gene trait cannot lead to changes in allele frequencies?
Natural selection acting on a single-gene trait can lead to changes in allele frequencies within a population. If individuals with a certain allele have a selective advantage, they are more likely to survive and reproduce, leading to an increase in the frequency of that allele in the population over time. This process is known as directional selection.
How do habitat and competition lead to speciation of Pollenpeepers on Warwick Archipelago?
how is natural selection occurring in the pollenpeepers
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 is the name for the process in which the organisms best adapted to their environment survive?
Its NaTuRaL sElEcTiOn if you didn't know.
Why is time an important factor in the process evolution by natural selection?
Because natural selection only preserves incremental beneficial traits to the organism and many different areas of the organism are undergoing mutation and natural selection at the same time against the backdrop of the immediate environment. If a population of organisms, subject to allele change due to natural selection, is not in a changing environment, or split in a allopatric event, then adaptive change will be very slow, or will not happen at all and selection will winnow those variants and stabilizing selection is taking place. Regression to the mean of phenotype.
What is a natural selection results?
Adaptions that lead to greater survivability and reproductive success in the immediate environment of the individual organisms under selection pressure.
What did Darwin propose by saying that over a long natural selection could lead to?
Darwin proposed that over a long time, natural selection could lead to the gradual change and divergence of species from a common ancestor, resulting in the formation of new species through the process of adaptation to their environment.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
