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:
- Homology - the structure is similar between the two species because of shared ancestry and common genetics.
- 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:
“The hill farmer ... always seems to make out somehow with his corn patch, his few vegetables, his rifle, and fishing rod. This self-contained economy creates in the hillman a comparative disinterest in the world’s affairs, along with a disdain of lowland ways. “I don’t go to question the good Lord in his wisdom,” runs the phrasing attributed to a typical mountaineer, “but I jest cain’t see why He put valleys in between the hills.””
—Administration in the State of Arka, U.S. public relief program (1935-1943)
“It is unheard-of, uncivilized barbarism that any woman should still be forced to bear such monstrous torture. It should be remedied. It should be stopped. It is simply absurd that, with our modern science, painless childbirth does not exist as a matter of course.... I tremble with indignation when I think of ... the unspeakable egotism and blindness of men of science who permit such atrocities when they can be remedied.”
—Isadora Duncan (1878–1927)
