- This Perspective discusses four questions of evolutionary biology that bridge macro and microevolution perspectives and proposes future research avenues to link evolutionary mechanisms and processes. Explaining broad molecular, phenotypic and species biodiversity patterns necessitates a unifying framework spanning multiple evolutionary scales. Here we argue that although substantial effort has been made to reconcile microevolution and macroevolution, much work remains to identify the links between biological processes at play. We highlight four major questions of evolutionary biology whose solutions require conceptual bridges between micro and macroevolution. We review potential avenues for future research to establish how mechanisms at one scale (drift, mutation, migration, selection) translate to processes at the other scale (speciation, extinction, biogeographic dispersal) and vice versa. We propose ways in which current comparative methods to infer molecular evolution, phenotypic evolution and species diversification could be improved to specifically address these questions. We conclude that researchers are in a better position than ever before to build a synthesis to understand how microevolutionary dynamics unfold over millions of years.

- We present a low-energy muon-spin-rotation study of the magnetic and superconducting properties of YBa(2)Cu(3)O(7-delta)/PrBa(2)Cu(3)O(7-delta) trilayer and bilayer heterostructures. By determining the magnetic-field profiles throughout these structures, we show that a finite superfluid density can be induced in otherwise semiconducting PrBa(2)Cu(3)O(7-delta) layers when juxtaposed to YBa(2)Cu(3)O(7-delta) "electrodes," while the intrinsic antiferromagnetic order is unaffected.
