In the 18th century, zoology passed through reforms provided by both the system of nomenclature of Carolus Linnaeus and the comprehensive works on natural history by Georges-Louis Leclerc de Buffon; to these were added the contributions to comparative anatomy by Georges Cuvier in the early 19th century.

Physiological functions, such as digestion, excretion, and respiration, were easily observed in many animals, though they were not as critically analyzed as was blood circulation. Following the introduction of the word cell in the 17th century and microscopic observation of these structures throughout the 18th century, the cell was incisively defined as the common structural unit of living things in by two Germans: Matthias Schleiden and Theodor Schwann.

In the meanwhile, as the science of chemistry developed, it was inevitably extended to an analysis of animate systems. And in the midth century the French physician and physiologist Claude Bernard drew upon both the cell theory and knowledge of chemistry to develop the concept of the stability of the internal bodily environment , now called homeostasis. The cell concept influenced many biological disciplines , including that of embryology , in which cells are important in determining the way in which a fertilized egg develops into a new organism.

The unfolding of these events—called epigenesis by Harvey—was described by various workers, notably the German-trained comparative embryologist Karl von Baer , who was the first to observe a mammalian egg within an ovary. Another German-trained embryologist, Christian Heinrich Pander , introduced in the concept of germ, or primordial , tissue layers into embryology.

In the latter part of the 19th century, improved microscopy and better staining techniques using aniline dyes, such as hematoxylin, provided further impetus to the study of internal cellular structure. The theory of evolution —that organisms are continuously evolving into highly adapted forms —required the rejection of the static view that all species are especially created and upset the Linnaean concept of species types.

Darwin recognized that the principles of heredity must be known to understand how evolution works; but, even though the concept of hereditary factors had by then been formulated by Mendel, Darwin never heard of his work, which was essentially lost until its rediscovery in Genetics has developed in the 20th century and now is essential to many diverse biological disciplines. The discovery of the gene as a controlling hereditary factor for all forms of life has been a major accomplishment of modern biology.

There has also emerged clearer understanding of the interaction of organisms with their environment. Closely related to this study of ecology are inquiries into animal behaviour , or ethology. Citation Impact 3. Skip to main content Advertisement.
