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.
No, natural selection is believed to result in evolution.
No, they are two different things.
No, it's exactly the other way around: natural selection causes adaptation.
mutation
Natural selection.
Natural selection can help creatures adapt to their enviorment. Sometimes this can cause unwanted problems.
no
natural selection
They aren't. Intelligent design posits that natural selection cannot create life as we know it, and inserts a deity as the cause.
Genetic variation. If there were no variation in the genes/phenotype then natural selection would have nothing to select from.
because the rocks are pretty
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.
