[S29] Integration of micro- and macroevolution
Evolutionary biology studies the patterns and processes that shape biodiversity over long and short timescales. Traditionally microevolution focused on within-species dynamics in a short temporal perspective, while macroevolution deals with both within- and between species patterns and processes over longer periods of time. Although many macroevolutionary patterns still lack explanations that follow from microevolutionary theory and observations, exiting new developments now allow both micro- and macroevolutionary approaches to converge on understanding biological variation within the context of genomic organization, historical constraint, contingency as well as elucidating biotic and abiotic drivers of evolutionary change. The increasing genetic resolution provided by next-generation-sequencing technology impacts studies of both micro and macro-evolution; phylogenetic analyses are now increasingly based on many markers and include genome organization, and functional traits are commonly being linked to causal genetic determinants. It is now also possible to combine palaeontological and neontological data in the same analysis framework. In this symposium, we will explore insights from such new developments and their potential for determining the research agenda for evolutionary biology. Contributions shall address fundamental questions regarding the integration of macro- and microevolution, for instance how can macroevolutionary studies inform hypotheses of microevolutionary change and vice versa?
