Evidence of Common Descent - Evidence From Artificial Selection

Evidence From Artificial Selection

Artificial selection demonstrates the diversity that can exist among organisms that share a relatively recent common ancestor. In artificial selection, one species is bred selectively at each generation, allowing only those organisms that exhibit desired characteristics to reproduce. These characteristics become increasingly well developed in successive generations. Artificial selection was successful long before science discovered the genetic basis. Examples of artificial selection would be dog breeding, genetically modified food, flower breeding, cultivation of foods such as wild cabbage, and others.

Famous quotes containing the words evidence, artificial and/or selection:

    Faith. Belief without evidence in what is told by one who speaks without knowledge, of things without parallel.
    Ambrose Bierce (1842–1914)

    When I hear the hypercritical quarreling about grammar and style, the position of the particles, etc., etc., stretching or contracting every speaker to certain rules of theirs ... I see that they forget that the first requisite and rule is that expression shall be vital and natural, as much as the voice of a brute or an interjection: first of all, mother tongue; and last of all, artificial or father tongue. Essentially your truest poetic sentence is as free and lawless as a lamb’s bleat.
    Henry David Thoreau (1817–1862)

    The books for young people say a great deal about the selection of Friends; it is because they really have nothing to say about Friends. They mean associates and confidants merely.
    Henry David Thoreau (1817–1862)
