Availability information for this program

Today the Animal Sciences, Zoology, form the knowledge basis for such diverse disciplines as human physiology and nutrition ... Genetics and animal breeding ... And the exciting field of wildlife ecology. For the first time the scientific discoveries that provide insight into the nature of animal classification, physiology and behavior are brilliantly brought together in one program. Arranged chronologically, each discovery is presented with clear graphics and brilliant High Definition footage.

Episodes:

• Animal Sciences

  Animal sciences are also known as zoology and study animals. 350 b.c. - Aristotle Founds Zoology Greek Science, was founded by Aristotle the first scientist in Greek history. 1735 - Carlos Linnaeus Begins the Modern Description of Life Animal classification was set down by Carlos Linnaeus And includes the phyla porifera, cnidaria, mollusks, arthropods, echinodermata and chordata. 1796 - Comparative Anatomy Comparative anatomy was developed by George Cuvier and uses the concepts of homologous structures and convergent evolution to compare the anatomy of animals. 1826 - All Animal Life Begins with an Egg Animal life cycles start from embryos, and some of these life cycles are complex, needing a larva to develop into an adult, while others are simple as the embryo develops directly into a juvenile form of the adult. 1859 - The Theory of Evolution The theory of Evolution was described by Charles Darwin in his book On the Origin of Species, and later was refined with the idea of punctuated equilibrium. 1973 - The Science of Animal Behavior The study of Animal behavior and behavior modification has been carried out by leading scientists such as Ivan Pavlov, Konrad Lorenz and Nikolaas Tinbergen. 1998 - Principles of Animal Communication The study of animal communication and how animal senses work was begun by Karl von Frisch.

• Environmental Sciences

  Ecology and the environment are part of conservation and environmental studies. 1920 - Biomes The world's biomes are tundra, coniferous forest, deciduous forests, grasslands, deserts, chaparral and tropical. 1928 - The Theory of Plant Succession Plant succession was first described by Frederic Clements to show how a plant community evolved. 1949 - Ecology The idea that ecology was important and needed an environmental ethic and a land ethic in order to sustains the ecosystem was first developed by Aldo Leopold. 1953 -Ecosystems The study of ecosystems was first written about by Eugene P. Odum. 1957 - Ecology's Concept of Niche Ecological niche, or niche, and habitat are two concepts introduced in the study of population ecology in order to define better ecosystem species and species population. 1969 - The Five Kingdoms of Life The Kingdoms of Life are based upon prokaryote cells and are the Kingdom of Monera, and eukaryote cells, which include fungi, protista, the animal kingdom and plant kingdom. 1979 - Gaia Hypothesis The Gaia Hypothesis was develop by James Lovelock. 1986 - Biodiversity The term Biodiversity was coined by E.O. Wilson to show the diversity in the world's ecosystems.

• Microbiology and Genetics

  Cytology, the structure of cells, is important to understanding microbiology and genetics. 1673 - Anton van Leeuwenhoek Describes Microscopic Life The study of cells was first started by Anton van Leeuwenhoek, who used a microscope to look at a single cell, and has grown to understand the roles of eukaryote cells, bacteria and prokaryote cells. 1878 - Germ Theory of Disease Bacteria, discovered by Louis Pasteur who showed they could cause infection, are known as a prokaryote cell and cause illness just like viruses can. 1884 - The Structure of Cells Biologists have long studied the cell structure, which is not the same for all cells and includes the cytoplasm, cell walls, cell nucleus, mitochondria, and unique to plants, chloroplasts. 1884 - Mitosis and Cell Division Mitosis describes the phases that occur in cell division for eukaryote cells to make sure that each daughter cell gets a complete set of chromosomes, hence genes; and that each daughter cell also receives some of all the other organelles, for example, mitochondria and ribosomes; while in bacteria cell division is simpler. 1905 - Meiosis The process of meiosis in biological reproduction shows how sex cells, carrying half the chromosomes of the mother cell cell, come about. 1911 - Genes Genes were discovered by American Thomas Hunt Morgan, who proved that they were places, or loci, along the chromosomes' DNA DNA, a breakthrough that in later half of the 20th century led to breakthroughs in genetic engineering. 1967 - The Symbiotic Cell The theory that a symbiotic cell gave rise to the eukaryote cell was first proposed by biologist Lynn Margulis.

• Plant Sciences

  Plant sciences are the study of plant life and are also known as botany. Chapter List 323 b.c. - Theophratus Founds Botany Theophrastus, the father of plant classification, was a leader of early Greek science and a great figure in Greek history. 1682 - Plant Physiology Plant classification, or plant types, classifies plants according to plant physiology, And includes those who reproduce by spores and those who reproduce by seeds such as gymnosperms and angiospoerms. 1694 - How Plants Reproduce Plant reproduction involves the male organ, a stamen, and the female organ, a pistil with an opening called the stigma, where pollen is deposited, a form of sexual reproduction first demonstrated by Rudolph Camerarius. 1838 - The Cellular Basis of Plant Life Cells were first discovered by Robert Hooke and later, Anton Van Leeuwenhoek, who invented the microscope which could see a single plant cell. 1866 - Mendel's Laws of Inheritance Gregor Mendel discovered the laws of inheritance for plant genetics. 1886 - Nitrogen-Fixing of the Pea Family Is Explained Plant nitrogen-fixing uses the bacteria identified as rhizobium and improves yields in agriculture. 1946 - Photosynthesis How Photosynthesis works was described by the Calvin/Benson cycle, named for its discoverer Melvin Calvin, and has become a central tenet in understanding global warming.
