Evolutionary biology

Prof. Dr. Siegfried Scherer
and coworkers

First, based on a variety of microbiological and molecular biological experimental strategies as well as bioinformatical analyses we study the presence, origin and evolution of overlapping genes in bacteria (see research groups functional characterization and bioinformatics and evolution).


Secondly, I am also interested in the broader theoretical analysis of evolutionary processes. What kinds of microevolutionary changes can be observed? How far-reaching are they? How fast do they occur? Which changes in biological information result from such processes? Have microevolutionary mechanisms been observed which are suitable to explain macroevolutionary transitions or does macroevolution involve additional factors?

Thirdly, I find it quite useful to evaluate the epistemological background of empirical theories (e.g., mechanisms of microevolutionary changes) and empirical-historical theories such as macroevolutionary transitions.
