Modern biology raises fundamental conceptual questions. One of them relates to the notion of causality, central to understanding the world around us. Do conventional notions of causality break down in the face of the extraordinary complexity of biological systems? Relatedly, what do we mean when we say that we can understand an organism (phenotype) by studying its DNA (genotype)? While questions like these have implications far beyond the sciences, other questions we ask are long-standing puzzles in evolutionary biology. How important is neutral change for evolutionary adaptation and innovation? And what is the role of randomness in Darwinian evolution? We aim to answer questions like these with approaches that range from experimental data analysis to mathematical modeling.
