Why do vestigial structures still exist in spite of natural selection?

Vestigial structures are the expressed genetic remnants indicatory of a species evolutionary past. In humans one such vestigial remnant is the coccyx, which were once part of tail structures in our primate ancestors.

∙ 13y agoEvolution is a slow process of trial and error. Vestigial organs are organs that once had a function in the ancestral body. They are no longer important, so the body puts less energy into developing them, but we still inherit these characteristics in our DNA. However, often organs that we consider vestigial still do serve some function, although we can survive without them.

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 happens in natural selection when living things face many challenges in the struggle to exist?
liveing things face many challenges in the struggle to exist
How does natural plasma exist?
Natural plasma exist only at very high temperatures, or low temperature vacuums.
What is the structures within the cytoplasm of eukaryotic cells?
organelles exist in the cytoplasm.
What species can evolve from natural selection?
Microevolution is merely evolution, the change in allele frequency over time in a population of organisms, and all animals do this all the time.Natural selection is always summing up the variation among a population of organisms and selecting those that show survivability and reproductive advantages, even is the selection does no more that stabilize the organisms phenotypes.Look to the evolutionary history of horses or whales to see clear examples of evolution and selection through time.
Can natural selection exist with out evolution?
Perhaps not, but evolution can exist without natural selection.
Does natural selection exist?
Of course!
Why is natural selection important for the animals?
Because all animals that exist have formed, and are being formed and re-formed, continuously, primarily by natural selection.
How did humans come to exist according to Darwin?
They evolved by a process of natural selection.
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 happens in natural selection when living things face many challenges in the struggle to exist?
liveing things face many challenges in the struggle to exist
How does natural selection relate to randomness?
In all natural processes, there is an element of chance. In natural selection, most of that chance is introduced by the randomness of the genetic variations it works with. But other elements of chance exist as well. Natural selection is a stochastic phenomenon: not every less able variant will produce less offspring than the more able variant; much depends on chance environmental circumstances.
How is the word 'astronomy' defined?
Astronomy is the science which studies natural non-biological physical structures that exist outside the Earth's atmosphere.
What did Darwin mean when he said that natural selection works on existing variation?
Natural selection is the differential reproductive success of genomic variation. But for differing variants to be able to compete reproductively, such variants must exist in the first place. Reproduction causes such variants to come into existence.
Do mutation evolution and natural selection apply to individuals or populations?
Since the natural selection is a theory, we can not apply a theory as a science. Even though some scientists believed in natural selection: think of Nazi scientists, Soviet scientists, etc. They were 100% evolutionist believers. Nobody yet seen atoms but we believe that they exist...strange. We apply faith in some modern science...hmmm...
The similarities in the Galapagos finches implied?
The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Does science say that god do exist?
No, science believes the Big Bang created the universe. Science believes that humans evolved from apes through the theory of natural selection.
