|Module title||The right tool for the job - some aspectsof ecological adaptations and speciation|
|Module lecturer||prof. UAM dr hab. Iwona Melosik|
|Lecturer position||profesor UAM|
|Faculty||Faculty of Biology|
The course is organized as fifteen 2-hour (2 x 45 min) lectures during the spring semester. Day and time will be given immediately before the start of the course.
Module aim (aims)
The goal is to provide a comprehensive introduction to the patterns and processes in species formation. The course will emphasize the genetics, geography, and ecology of speciation. Theoretical concepts will be complemented by empirical studies across the Tree of Life.
Pre-requisites in terms of knowledge, skills and social competences (where relevant)

Week 1 Populations as a unit of evolution - basic terms and concepts; Metapopulation model and dynamics
Week 2. Markers and methods used in studies on speciation.
Week 3-4 Speciation as a process linking micro-and macroevolution.
Week 5. Genetic drift (causes and properties) and the speciation process.
Week 6. Natural selection (requirements, types, consequences - types of adaptations).
Week 7 Darwin's "Mystery of Mysteries" and Modern Synthesis.
Week 8 Barriers to Reproduction. The role of geography in the speciation process.
Week 9 Ecological speciation.
