Learning objectives
This Module of General Zoology is designed to provide the bases for addressing the study of animal biology that will be detailed in the second part of the year (cfr. the Course of Systematic Zoology) and in the subsequent years.
In particular the Course will allow the student to:
- Tackle the study of Zoology with an evolutionary-adaptive approach (Knowledge and understanding).
- Understand the basic principles and mechanisms of evolution and organization and structure of animals, in addition to the morpho-functional systems of the main Taxa (Knowledge and understanding).
- Acquire the basic and methodological principles for a better understanding of the other Courses in the following years that will deal with different aspects of animal biology (Knowledge and understanding).
- Acquire the basic elements of methods and scopes of scientific research with particular emphasis on Zoology (Knowledge and understanding) (Making judgements).
- Identify connections among studied topics and linking them to basic or similar disciplines (Learning skills) (Making judgements).
Prerequisites

Course unit content
The course of General Zoology provides the basic elements of animal biology with particular emphasis to morpho-functional, ecological and evolutionary aspects.
The Course is also aimed to provide general information on the scientific method and basic methodology of zoological research.

Bibliography
Slides, specific scientific articles and links to web sites will be available to download by the students on the web platform “Elly”. Instructional materials could be updated during the Course.
Textbooks:
CAMPBELL – BIOLOGIA E GENETICA di Reece et al., Pearson (2015)
CAMPBELL – MECCANISMI DELL’EVOLUZIONE E ORIGINI DELLA DIVERSITÁ, di Reece et al., Pearson (2015)
CAMPBELL – LA FORMA E LA FUNZIONE NEGLI ANIMALI, di Reece et al., Pearson (2015)
Teaching methods
Lectures made using also multimedia tools on the classical topics of general Zoology. Analysis of case studies for a better understanding of the principles and the experimental methods used in the field of animal biology.
Slide used during classes will be weekly available to download on Elly platform. To download the slides, students need to be registered on-line to the Course.
Importantly, the slides are not a substitute for lessons or of the Textbooks but are considered part of the accompanying instructional materials. Students should frequently control instructional materials and other information provided by the Teacher on the Elly web site.
Assessment methods and criteria
The method of verifying learning may be different based on the progress of the Covid 19 emergency. Two possible methods are envisaged.
1) IT IS POSSIBLE TO CONDUCT EXAMINATIONS IN PRESENCE. In this case the examination will be written (multiple choice test) aimed to: verify the capacity of the student to tackle problems of of zoology using the methodological principles and knowledge acquired during the course; evaluate the student's ability to carry out cross-links between the various topics covered during the Course.
The exam is passed with a score of at least 18. The maximum possible score is 32 (2 points for ech complete answer, 1 for partial answer evaluated on the basis of the multiple choice available); 30 cum laude is obtained with a score of 31 or 32.
2) IT IS NOT POSSIBLE TO CARRY ON EXAMINATION IN PRESENCE (ONLY ON-LINE). In this case, the assessment will take place through a test in which the teacher, through a series of adequately structured multiple choice questions, will evaluate the student's abilities as described above.
Please note that the course of General Zoology is the first module of the integrated course "General and systematic Zoology" (12 CFU) whose overcoming requires a positive score in both modules of 6 credits of which it is composed. The final grade is the average of the ratings given in the two modules.
