**Description**:

Evolution shapes the currently observed patterns in biological populations and their future variation. Understanding the underlying process in its entirety requires to equally understand the effect of each force in isolation as well as their interplay. In many practical situations, evolutionary drivers have to be inferred in retrospect. In this context, the embedding of the corresponding genealogies into a rigorous mathematical framework has been extremely useful for the development of practical inference tools. The analysis of the corresponding ancestral processes – the most famous one being the coalescent – is mathematically challenging, and it has also incited a fair amount of mathematical research. The mini-symposium offers a selection of current theoretical studies of evolutionary effects when they are considered in isolation as well as in their interplay. The four talks have in common to use ancestral processes for the derivation of their results.
