  Morphology - LoveToKnow 1911
His classification of animals, too, was largely natural, and, though on the whole he lent his authority to maintain the notion of three kingdoms of nature, he at least at one time discerned the fundamental unity of animals and vegetables, and united them in opposition to the non-living world as Organisata.
The Regne animal (1817) and the theory of types (vertebrate, molluscan, articulate, and radiate) are the results of this union of analysis and synthesis and mark the reconstitution of taxonomy on a new basis, henceforth to be no longer a matter of superficial description and nomenclature but a complete expression of structural resemblances and differences.
In Carus's System of Animal Morphology (1853) another theory was propounded, but the problem then seems to have fallen into abeyance until 1865, when it formed the subject of a prolonged and fruitful discussion in the Principles of Biology.

This leads to a determination of whether the animal is a predator or prey.
The class will be allowed to ask four questions relative to where the animal lives, what it eats, type of dwelling, locomotion and then they will be asked to draw a simple schematic diagram of what they think the animal looks like using circles and ellipses.
Thus the approach moves away from the standard textbook situation to one wherein the student is actually using tools utilized by zoologists in the laboratory.

 Anatomy - Wikipedia, the free encyclopedia
Anatomy (from the Greek anatome, from ana-temnein, to cut up), is the branch of biology that deals with the structure and organization of living things.
Animal anatomy may include the study of the structure of different animals, when it is called comparative anatomy or animal morphology, or it may be limited to one animal only, in which case it is spoken of as special anatomy.
From a utilitarian point of view the study of humans is the most important division of special anatomy, and this human anatomy may be approached from different points of view.

 Molecular biologists prune branches from the animal family tree
Their work substantiates earlier genetic investigations suggesting that the vast majority of animals, from oysters to humans, belong to one of three primary evolutionary lines, rather than the multiple branches suggested by morphological studies.
On the new, gene-based tree, animals with backbones are on the same branch as starfish and their relatives -- a longstanding classification based on similarities in development.
Animals that molt, such as crustaceans, insects, roundworms, and priapulids, now sit together on a second branch.

 Sean B. Carroll, Ph.D.
Carroll's research focuses on the way new animal forms have evolved, and his studies of a wide variety of animal species have dramatically changed the face of evolutionary biology.
Carroll and his colleagues chose to study the evolution of the wing spot on fruit flies because it is a simple trait with a well-understood evolutionary history.
The discovery is important because it provides critical evidence of the way that animals evolve new features to improve their chances of reproductive success and survival.

 morphology --  Encyclopædia Britannica   (Site not responding. Last check: 2007-11-01)
in biology, the study of the size, shape, and structure of animals, plants, and microorganisms and of the relationships of the parts comprising them.
Morphology deals with the structure and form of plants and includes such subdivisions as: cytology, the study of the cell; histology, the study of tissues; anatomy, the study of the organization of tissues into the organs of the plant; reproductive morphology, the study of life cycles; and experimental morphology, or morphogenesis, the study of development.
The morphology of verbal focus has attracted the most attention in Austronesian studies, but other areas of morphology are also of interest.

 Common genes form new family tree for animals
For more than a hundred years, scientist have depended on morphology, the form and structure of animals, to determine their place on the family tree.
The new study was based on exploration of so-called Hox genes in three distinct kinds of animals: an unsegmented marine worm related to insects, an unusual marine animal called a lamp shell, and a segmented worm related to earthworms
All of the animals involved in the new study, although from widely divergent parts of the animal kingdom, have similar Hox genes, although with slight but significant variations, said Grenier.

 Embryology (from morphology) --  Encyclopædia Britannica
It embraces all conceivable forms of study, not only of the components of the animal body and the vital processes that sustain it but also of the relations of individual animals or animal groups with one another and the environment.
The features may be readily apparent, such as needles on a cactus plant, or they may be microscopic, such as chloroplasts (chlorophyll-containing structures that are contained in the cells of green plants).
Morphologists are interested in questions such as how the fang mechanisms of cobras differ from those of rattlesnakes or how the wings of bats evolved from the forelimbs of their ancestors.

Challenging this view, Lynn Nyhart argues that morphology was integral to the life sciences of the nineteenth century.
Although there were neither professors of morphology nor a morphologists' society, morphologists achieved influence by "colonizing" niches in a variety of disciplines.
She examines the intertwined histories of morphology and the broader biological enterprise, demonstrating that the study of form was central to investigations of such issues as the relationships between an animal's structure and function, between an organism and its environment, and between living species and their ancestors.

The extraordinary conservation of Hox DNA-binding domains among extant bilaterians, and their linkage to "body plan" aspects of morphology, generates excitement that we are on the cusp of discovering the ultimate root of homology through the analysis of developmental genes and their regulation.
The author, professor of zoology at the University of Padua and an acclaimed morphologist and systematist, uses his deep knowledge of animal morphology not only to caution the genes-up view through numerous illuminating exceptions to accepted general rules, but also as a basis for posing new developmental models.
The author begins his discussion of "Axes and Symmetries" by describing the functional disassociation of the somatic \(ecto-mesodermally derived) and the visceral (endodermal) body axes of various bilaterians, mainly polypoid, with gut looped such that anus is relatively close to the mouth.

We marvel at the obstinacy with which he, with inadequate mathematical knowledge, opposed the Newtonian theory of light and colour; and at his champion-ship of " Neptunism," the theory of aqueous origin, as opposed to " Vulcanism," that of igneous origin of the earth's crust.
Of far-reaching importance was, on the other hand, his fore-shadowing of the Darwinian theory in his works on the meta-morphosis of plants and on animal morphology.
Modern, too, was the outlook of the aging poet on the changing social conditions of the age, wonderfully sympathetic his attitude towards modern industry, which steam was just beginning to establish on a new basis, and towards modern democracy.
