Genomics of Adaptation and Speciation
summer semester 2018
09 Apr 2018 - 14 Jul 2018
Prof. Dr. Jochen Wolf
Dr. Ricardo J Pereira
Species formation has fascinated evolutionary biologists for centuries. How does natural selection lead to local adaptation? Can genetic incompatibilities maintain species borders? How do these processes interact during the continuum of species formation? These questions have remained unanswered largely due to the lack of genomic tools that can be applicable across species. The recent advent of high-throughput sequencing has unlocked these limitations and allows applications to virtually any kind of organism. In this seminar, we will discuss the most recent papers defining new benchmarks in genomics of speciation. We will discuss foundational theory supporting new research questions, advantages of current genomic methodologies, and the limitation defining future advances of the field.
In this master-level course, you will:
- Get familiar with long standing questions and theory on speciation research;
- Understand the advantages and limitations of new genomics methods;
- Identify opportunities for future research.
The program of this seminar covers essential topics on Adaptation and Speciation (see the program below).
Each class consists of a short lecture introducing the core concepts of that topic, followed by the discussion of current papers.
Each student selects a topic according to her/his own research interests, selects a paper from a suggested list or equivalent, and will
However, everyone is expected to

This seminar assumes that students are confortable with key concepts of the following disciplines:
- Population Genetics;
Previous atendance to these disciplines during undergraduate or master courses is not enforced, but students are expected to do a self-assessment of their background and complement potential caveats with the review articles suggested below or background reading on specific topics.
- pereira AT bio.lmu.de
- j.wolf AT bio.lmu.de
3 ECTS, 2 SWS
Every week, Monday, 8:30-10:00
Biozentrum (room B01.015)
In order to pass, students must lead the discussion of one paper (i.e. presentation of an article) and participate actively in the discussion of any of the other topics.
Thu final grading is based both on the presentation (50%) and on the student's participation in the discussion throughout the entire course (50%).
Below there's a description of the topics addressed in each discussion session, along with a list of key concepts and suggested papers.
Students are free to suggest papers beyond this list, as long as it covers the same topic and one of the key concepts.
The estimated dates of discussion sessions and the initials of the initials of the discussion leader/s are marked below, but note that these are subjected to changes during the course of the semester. Papers chosen for each discussion session are marked in bold
