报告主要内容：Study of variation in observable biological features (morphological variations, phenotypic traits) in an organism (species) is an old area of biology. Darwin uses "variation" as a cornerstone of his theory of evolution. In this expository lecture, I discuss examples morphological variation in diverse contexts. Then I provide unifying mathematical interpretations of certain concrete biological questions. Using contemporary understanding of molecular networks and their dynamics, I propose rigorous computational approaches to verify the mathematical conjectures and to test the related biological hypotheses regarding morphological variations and quantifying phenotypic traits.
