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.

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.
How does environmental pressure affect natural selection?
When nothing happens to exert strong population pressure on that population, natural selection favors the allele frequency already present. When mutations cause new traits, natural selection weeds these traits out because they're not as efficient as the others.
What are the pressures of natural selection?
Everything from available food to climate will cause the changes we see in natural selection. Random mutations occur constantly and when those mutations are beneficial for life, the genetic code is more likely to be passed on to future generations.
Adaptation which allows for natural selection is called?
Adaptation does not allow for natural selection: natural selection causes adaptation.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
Is natural selection a cause of evolution?
No, natural selection is believed to result in 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.
What can cause natural selection to go faster?
mutation
Which mechanism of evolution can cause adaptation?
Natural selection.
What are the advantages and disadvantages of natural selection to an organism?
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
Can RNA undergo a natural selection and cause evolution or change?
no
What is the name of the process that cause a species to evolve?
natural selection
How are intelligent design and natural selection alike?
They aren't. Intelligent design posits that natural selection cannot create life as we know it, and inserts a deity as the cause.
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.
How does natural selection and variation help cause evolution?
because the rocks are pretty
Does natural selection cause changes in the environment?
No, natural selection is the environment! The variant organism is selected against the immediate environment where it survives and reproduces better than it's conspecifics.
