Course Objectives
The course aims at illustrating the evolutionary processes and patterns generated by these, with the main objective of developing a scientific view of biological diversity that goes beyond the mere description. The pattern of diversity, the structure-function relationships and adaptations of organisms to their environment will be the main topics of discussion in the light of evolutionary mechanisms. The student will acquire knowledge on some fundamental topics for a biologist as the theory of evolution by natural selection, the concept of fitness and adaptation, the genetic basis of evolutionary change, speciation, molecular evolution, the principles of systematics, paleontology, macroevolutionary patterns, the phenomena of extinction and the relationship between developmental biology and evolutionary processes. Through discussion of the major themes of evolutionary biology, the student will understand the reasons that make this discipline the central unifying theme of biology. Didactic material will allow the student to evaluate and elaborate the international literature on evolution.
The students will be able to describe the processes that have led to the evolution of animal biodiversity, to evaluate the organization of animals, and to correlate the organization plan of the main body structures to adaptive and evolutionary aspects. They will also acquire the key concepts, criteria, and methods of evolutionary biology, knowledge on the importance of evolution, and skills for the analysis of the processes that regulate the evolution of organisms.
Course Prerequisites
Previous knowledge on animal biodiversity, genetics, and molecular biology is required.
Teaching Methods
The course is organized in lectures. Powerpoint presentations will be used during lectures.
Assessment Methods
Exam sessions are foreseen in the number planned by the Degree Course. The examination consists of an oral interview (two questions) and the outcome of the examination will be marked out of thirty. The acquisition by the student of knowledge concerning the processes that have led to the evolution of animal biodiversity will be assessed. The evaluation will take into account the capacity of learning, consultation, and processing of bibliography, and the ability to critically discuss and comment the information acquired during the course.
