  1. Abstract Ever since the Modern Synthesis, a debate about the relationship between microevolution and macroevolution has persisted—specifically, whether they are equivalent, distinct, or explain one another. How one answers these questions has become shorthand for a much broader set of theoretical debates in evolutionary biology. Here, we examine microevolution and macroevolution in the context of the vast proliferation of data, knowledge, and theory since the advent of the Modern Synthesis. We suggest that traditional views on microevolution and macroevolution are too binary and reductive given current empirical and theoretical advances in biology. For example, patterns and processes are interconnected at various temporal and spatial scales and among hierarchical entities, rather than defining micro- or macro-domains. Further, biological entities have variably fuzzy boundaries, resulting in complex evolutionary processes that influence macroevolution occuring at both micro- and macro-levels. In addition, conceptual advances in phylodynamics have yet to be fully integrated with contemporary macroevolutionary approaches. Finally, holding microevolution and macroevolution as distinct domains thwarts synthesis and collaboration on important research questions. Instead, we propose that the focal entities and processes considered by evolutionary studies be contextualized within the complexity of the multidimensional, multimodal, multilevel phylogenetic system.
