Learning objectives
Students will learn the “vertebrate story,” and in doing so will not only gain an understanding of vertebrate form and function in an evolutionary and ecological context, but will also learn how to think in a more conceptual, scientific, and comparative manner. GOALS: The goals of this course are simple: 1) To learn about and gain an appreciation for vertebrate diversity, 2) To set forth the basic structure of vertebrates, 3) To discuss the functional morphology of anatomical systems, 4) To relate form to function in an ecological context, and thus 5) To discuss the major adaptive changes in vertebrate evolution. Students will be encouraged to think critically about how organisms work and how vertebrates might have evolved their remarkable and complex adaptations.
Prerequisites
Students must have a strong background in general zoology: animal reproduction, theory of evolution, speciation and systematics.
Course unit content
The course will describe the evolution of Vertebrates from their appearance on Earth, with an outline to present problems about their conservation. Lectures will focus on the morphological, ecological, behavioral and physiological diversity within an evolutionary perspective. Major topics will include phylogenetic hypotheses of relationships, comparative anatomy, functional morphology, natural history, and biogeography of fossil and living vertebrates.

Teaching methods
The lectures take place illustrating general concepts that are detailed with examples of animal taxa. The lectures are held using PowerPoint presentations that are made available to students on the ELLY site. Practical exercises include fish dissection, bird species recognition in the field, visit to the natural history museum.
Assessment methods and criteria
After taking this course, a student should be able to: 1. Apply the scientific and comparative methods to the study of vertebrates. 2. Recognize the basic structures and organization of the vertebrate body. 3. Know and use the basic terminology used in discussion of vertebrate zoology. 4. Know the theory, mechanisms, outcomes, and history of vertebrate evolution. 5. Analyze and compare vertebrate form and function in an ecological and evolutionary context. 6. Discuss different classification, taxonomic, and systematic approaches used in vertebrate zoology. 7. Identify the major vertebrate groups. Written examination (1-hour time available) (consisting of 10 multiple choice questions, 1 point for each correct answer and 2 open questions, from 0 to 10 point each for clarity, synthesis, completeness, correctness, relevance). 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.
In case of health emergency oral exam will be carried on.

2030 agenda goals for sustainable development
The course is aimed to increase the knowledge of Vertebrates biodiversity and the discussion of some cases of species extinction due to the anthropic impact. A second aim is to raise students' awareness of the need to conserve natural habitats and to contrast an ecologically not sustainable development.
