Learning objectives
The Zoology course is part of the Integrated Course on Histology, Embryology and Zoology. The module aims at enabling the student to: 1: know and understand basic theoretical elements of biology, evolution and taxonomy and principles of eco-ethology; 2: knowledge and understanding applied in recognition of morphological and functional characteristics of invertebrate and vertebrate taxa of veterinary interest; 3: making judgements on scientific valence on modern evolution theories; 4: communication skills to illustrate the most striking features of animal taxa; 5: learning skills through the use of the textbook and discussion with the teacher.
Prerequisites
Basic biology knowledge as required by rule of admittance test. Any debt (OFA) will be settled with a 2 hr class followed by an oral examination concerning the arguments explained.
Course unit content
The course provides basic knowledge to the understand the complexity and diversity of the animal world and leads students through the evolutionary processes that characterize it. The first part concerns basic animal biology topics such as: origin and evolution of life on Earth, Evolution theory, microevolution, structures e functions in animals. The second part of the course is directed to the study of the systematic and evolution of the most important animal taxa from a veterinary point of view. In the third part of the course elements of ethology and animal’s domestication are presented.
Full programme
PRELIMINARY INFORMATION
During the first class, information about the program, the aims of the Course and the examination methods will be proved. Information on the teaching materials available for the students as well as a list of suggested text books will be provided.
AN INTRODUCTION TO THE STUDY OF ANIMAL BIOLOGY. The study of Life. The unifying themes of Life Sciences. Zoology as a part of Biology. Zoology as a scientific process.
DD: Knowledge and understanding; making judgements; applying knowledge and understanding
THE ORIGIN OF LIFE: The pre-biotic world. From the molecules to the organisms. The emergence of eukaryotes. The origin and evolution of animals.
DD: Knowledge and understanding
EVOLUTION: The idea of evolution: historical background. The theory of Darwin and evidences supporting it. The meaning of “theory” in the scientific thinking. The evolution of populations and the forces of evolution. Microevolution. Speciation and mechanism of reproductive isolation. Macroevolution.
DD: Knowledge and understanding; making judgements; applying knowledge and understanding
POPULATION GENETICS: allelic frequencies and genotype frequencies, equilibrium of Hardy-Weinberg. Evolutionary forces: mutation, migration, natural selection and genetic drift, balanced polymorphism. DD: Knowledge and understanding skills; Autonomy of judgment; Knowledge and understanding skills applied
EVOLUTION AND SYSTEMATIC. Species: concept of species, reproductive barriers, models of specialization, (sympathetic, parapatric, allopathic). Phylogenetic reconstruction and biological classification: concept of homology and the like, phylogenetic analysis to establish relationships between taxa on a morphological or molecular basis; The concept of structural plan. DD: Knowledge and understanding skills; Autonomy of judgment; Knowledge and understanding skills applied.
MAIN PHYLA: with focus on those of veterinary interest: Porphera, Cnidaria, Platyhelminthes, Nematoda, Acanthocephala, Annelida, Mollusca, Arthropod, Echinodermata, Chordata. DD: Knowledge and understanding skills; Knowledge and understanding skills applied.
BASIC ELEMENTS OF ANIMAL BEHAVIOR. Reflexes. Fixed action patterns, Innate and acquired behavior. Classical and instrumental conditioning. Genetics of behavior, evolution and domestication. Social and reproductive behavior. Communication. Social and reproductive systems. Stress, welfare and abnormal behaviors. DD: Knowledge and understanding skills; Autonomy of judgment; Knowledge and understanding skills applied

Students can find the pdf slides showed in class on the Elly platform. The slides should be used EXCLUSIVELY to keep track of the topics covered in class and DO NOT REPLACE the textbook
Teaching methods
The lectures take place illustrating general concepts that are detailed with examples of animal taxa of veterinary interest. The lectures are held using PowerPoint presentations that are made available to students on the ELLY site. Practical exercises include: 1. a visit to the Museum of Natural History in Milan to have an evolutionary view of the animal kingdom; 2) video analysis of animal behavior
In case of prolonged health emergency due to the COVID-19 pandemic, the teaching could include lessons in mixed modality (frontal lessons for students in presence and simultaneously in live streaming on the electronic platform of the university). The recording of the lessons will be available on Elly for the three days following the lesson.
Assessment methods and criteria
Written examination (consisting of 20 multiple choice questions and 2 open questions) followed by an oral examination. Aims: to verify the capacity of the student to tackle problems of zoology using the methodological principles and knowledge acquired during the course; to evaluate the student's ability to carry out cross-links between the various topics covered during the Course. For students with DSA certified according to Law 170/2010, there are appropriate support methods.
In case of restrictions for reasons of public health the methods of assessment could be changed and adapted to on line modality.
