It is called evolution. After all, all characteristics, as far as evolution is concerned, are intermediate. They're all temporary variants, on their way to becoming something else.
The Peppered moth avoids predation by using camouflage to blend int to tree bark. It was originally white with black spots. However in the industrial revolution when the local trees were blacked by soot from the factory chimneys, a black variant with white spots became prevalent in these regions. In the areas of pollution the black version blended in and the white stood out so natural selection changed the appearance of the population in these areas.
Evolution states that a species will change to become more suited to its environment. Natural selection is survival of the fittest. The newly evolved version of the species is more fit to survive, therefore thriving.
Just because an allele is dominant does not mean that it is necessarily common.How common a version of a gene is (i.e. its frequency in a population) depends on how it affects an organism's chance of surviving to reproduce. Natural selection may favor a recessive allele of one gene and a dominant allele of another.
Alfred Russel Wallace.Wallace was a naturalist who independently came up with the idea of natural selection while traveling in what is now Malaysia and Indonesia. He sent a letter outlining his ideas to Charles Darwin, to whom it came as a great shock.Darwin had been working on his theory of natural selection for at least 20 years and did not know what to do. His friends Charles Lyell and Joseph Hooker decided that the fairest thing to do was to present Wallace's essay and Darwin's own writings jointly to the Linnean Society in 1858.Meanwhile Darwin rushed to complete a shorter version of his intended book, which was published in 1859 as 'On the origin of species'.You can see the letters at www.linnean.org/index.php?id=380
An inner cytoskeleton with hollow, protein microfilaments and connecting intermediate filaments make up the "backbone" of the cell that allows it to maintain it's structure. Whip like tails called flagella, and small, shorter version of flagella called cilia, help cells move. :)
stabilizing selection
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.

Much of "On the Origin of Species" comes from Darwin's studies of farm animals and domestic livestock. While human selection is NOT natural selection, selective breeding can be seen as an accelerated, exaggerated and unnatural version of the same process. Farmers know it works, and were, after all, the ones who started the practice thousands of years ago.
Directional selection is when natural selection favors a single phenotype. It occurs when there is a shift in population towards an extreme version of a beneficial trait.
modularity
An intermediate exhaust pipe generally refers to the pipe that comes directly off of the manifold, and to which the catalytic converter, or mid-tail pipe section is bolted /welded too. On newer cars and trucks, the intermediate pipe sometimes has a bendable section that looks like a scaled up version of a braided tube.

No Elements version have the pen tool. The vector features are limited, but the selection tools are very good, especially with version 14.
