Fitness Landscape

A fitness landscape, first conceptualized by Sewall Wright, is a way of visualising fitness in terms of a high-dimensional surface, in which height indicates fitness, and each of the other dimensions represents allele identity for a different gene. Peaks correspond to local fitness maxima; it is often said that natural selection always progresses uphill but can only do so locally. This can result in suboptimal local maxima becoming stable, because natural selection cannot return to the less-fit "valleys" of the landscape on the way to reach higher peaks.

Famous quotes containing the words landscape and/or fitness:

    The curfew tolls the knell of parting day,
    The lowing herd wind slowly o’er the lea,
    The ploughman homeward plods his weary way,
    And leaves the world to darkness and to me.
    Now fades the glimmering landscape on the sight,
    And all the air a solemn stillness holds,
    Save where the beetle wheels his droning flight,
    And drowsy tinklings lull the distant folds.
    Thomas Gray (1716–1771)

    Critics generally come to be critics not by reason of their fitness for this, but of their unfitness for anything else. Books should be tried by a judge and jury as though they were a crime, and counsel should be heard on both sides.
    Samuel Butler (1835–1902)
