Plant Morphology - A Comparative Science

A Comparative Science

A plant morphologist makes comparisons between structures in many different plants of the same or different species. Making such comparisons between similar structures in different plants tackles the question of why the structures are similar. It is quite likely that similar underlying causes of genetics, physiology, or response to the environment have led to this similarity in appearance. The result of scientific investigation into these causes can lead to one of two insights into the underlying biology:

  1. Homology - the structure is similar between the two species because of shared ancestry and common genetics.
  2. Convergence - the structure is similar between the two species because of independent adaptation to common environmental pressures.

Understanding which characteristics and structures belong to each type is an important part of understanding plant evolution. The evolutionary biologist relies on the plant morphologist to interpret structures, and in turn provides phylogenies of plant relationships that may lead to new morphological insights.

Famous quotes containing the words comparative and/or science:

    If you believe that a nation is really better off which achieves for a comparative few, those who are capable of attaining it, high culture, ease, opportunity, and that these few from their enlightenment should give what they consider best to those less favored, then you naturally belong to the Republican Party. But if you believe that people must struggle slowly to the light for themselves, then it seems to me that you are a Democrat.
    Eleanor Roosevelt (1884–1962)

    If science fiction is the mythology of modern technology, then its myth is tragic.
    Ursula K. Le Guin (b. 1929)
