Scientists used hidden DNA “time stamps” to uncover the surprisingly complex evolutionary journey that built the modern strawberry genome. Credit: Shutterstock Many of the world's most important crops have unusually complex genomes created through repeated rounds of whole-genome duplication and hybridization. These so-called polyploid genomes contain multiple sets of chromosomes inherited from different ancestral species. However, determining exactly how those genomes were assembled can be
