Zoology Essay - 1264 Words

Zoology The study of zoology can be viewed as a series of efforts to analyse and classify animals. Attempts at classification as early as 400 BC are known from documents in the Hippocratic Collection. Aristotle, however, was the first to devise a system of classifying animals that recognized a basic unity of plan among diverse organisms; he arranged groups of animals according to mode of reproduction and habitat. Observing the development of such animals as the dogfish, chick, and octopus, he noted that general structures appear before specialized ones, and he also distinguished between asexual and sexual reproduction. His Historia Animalium contains accurate descriptions of extant animals of†¦show more content†¦Perhaps the most important naturalist of the era was the German scholar St Albertus Magnus, who denied many of the superstitions associated with biology and reintroduced the work of Aristotle. The anatomical studies of Leonardo da Vinci were far in advance of the age. His d issections and comparisons of the structure of humans and other animals led him to important conclusions. He noted, for example, that the arrangement of joints and bones in the leg are similar in both horses and humans, thus grasping the concept of homology (the similarity of corresponding parts in different kinds of animals, suggesting a common grouping). The value of his work in anatomy was not recognized in his time. Instead, the Belgian doctor Andreas Vesalius is considered the father of anatomy; he circulated his writings and established the principles of comparative anatomy. Classification dominated zoology throughout most of the 17th and 18th centuries. The Swedish botanist Carolus Linnaeus developed a system of nomenclature and classification that is still used today—the binomial system of genus and species—and established taxonomy as a discipline. He followed the work of the English naturalist John Ray in relying upon the form of teeth and toes to differentiate mammals and upon beak shape to classify birds. Another leading systematist of this era was theShow MoreRelatedPhysical And Mental Requirements Of Zoology1155 Words   |  5 Pages One of the most interesting jobs of today is a Zoologist.

For an ornithologist, there is no standard or even an average starting salary because few people are hired strictly as ornithologist. Instead, they are hired as teachers, professors, wildlife biologists, environmental scientists, environmental educators, ecologists, tour leaders, andRead MoreAs Times Change : Traditional Vs.

Exotic animals were seen as status symbols. With the rule of Louis XIV, in 1664 AD, the modern conception of zoology came into place and ancient animal collections expanded to become a zoological park. As urbanization was set in motion, and the distinction between country and city became more prevalent, urban citizens felt the need to reconnect with nature.

The two perspectives for teaching zoology are the Linnean taxonomical and the Phylogenetic clade-based perspective. The Linnean taxonomical perspective is a rank-based hierarchy while the phylogenetic clade-based perspective groups species by focusing a common ancestor and its descendants. In regards to teaching zoology there is more value in using the phylogenetic clade-based perspective rather than the Linnean perspective becauseRead MoreThe University Of Wisconsin Madison1597 Words   |  7 Pageschoose if I attend this college would be Zoology.

The majority of species belonging to Gastropoda are herbivorous (Integrated Principles of Zoology, 2014). The primordial feeding behaviour involved grazing of algae from hard surfaces. The original, primitive form of radula called the rhipidoglossan is still present in some species of the order Archaeogastropoda that feed in this primordial manner
