How can natural selection cause the appearance of a new species?

Evolution causes the appearance of a new species through mutations in exisiting lifeforms. Natural selection is the method through which species become greater or lesser in numbers. For example, if you have a bunch of blue butterflies and a bunch of brown butterflies in a forest that is primarily brown,green, and black, then the blue butterflies have a greater chance of being eaten by predators than the brown butterflies because the brown ones could camoflauge themselves next to a tree. The blue ones would decrease in numbers and not be the most "fit" for their environment due to this process of natural selection.
Hope that rambling answer helped :)

How does variation work to help cause evolution?
You have to have variation in order to be able to have more successful variations, which succeed in evolutionary terms, and less successful variations which fail. If there were no variation in a species, there would be no natural selection.
What mechanism did Charles Darwin believe caused evolution?
Natural Selection is what Darwin believed was the cause of evolution.
What factors generally cause mass extinction?
The factors that generally cause mass extinction are changes in the natural ecosystem of the species. This may make it difficult for the species to reproduce and to stay alive.
Do the species on our earth change over time?
Yes, it is called evolution. It happens because individuals in the species die and new ones are born. The new individuals are slightly different than the old individuals. Selection processes of many different types cause more individuals that are less well adapted to the selection criteria to die, resulting in shifts that result in the species being better adapted overall to those selection criteria.
Which not a possible consequence of the introduction of invasive species?
Invasive species of plants or animals can cause a disruption in the natural food chains of a particular area. This can lead to the dying off of species normally found in that area.
What is the name of the process that cause a species to evolve?
natural selection
What a cause of natural selection?
The cause of natural selection is a change in the environment of a species. This change can have many causes. E.g. climate change, introduction of a new species, flooding, etc. When such an environmental change occurs, the individuals which are the most fit will have the biggest probability to survive and change the relative gene frequency in a species' genetic pool.
Is natural selection a cause of evolution?
No, natural selection is believed to result in evolution.
How do variation and natural selection work together to cause evolution?
They help each other by gradually accumulate in a species, while unfavorable ones may disappear. Over a long time, natural selection can lead to changes.
Is natural selection a cause of speciation?
Yes. Without natural selection there might probably still be change, but it would produce a fine gradient of diverging morphologies in every 'direction' of change. Natural selection limits the 'directions' of change, thereby producing distinct morphologies and thus distinct species.
How did Darwin explain why Galapagos species had different adaptions and similar South American species?
Define the term Variation and natural selection how do they work together to help cause evolution
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
Is natural cause the same as natural selection?
No, they are two different things.
Is adaptation a cause of natural selection?
No, it's exactly the other way around: natural selection causes adaptation.
Which mechanism of evolution can cause adaptation?
Natural selection.
What can cause natural selection to go faster?
mutation
Does natural selection cause variety of life on earth?
Yes, natural selection causes evolution, which results in the variety of life on earth.
