Genetic variation within Drosophila populations underpins our understanding of how organisms adapt to changing environments. As a premier model, Drosophila offers finely resolved genomic tools and ...

Traditionally, differences among individuals have been divided into genetic and environmental causes. However, both types of variation can underlie regulatory changes in gene expression — that is, ...

In a first-of-its-kind experiment tracing evolution across 25 generations, scientists have discovered that marine copepods—the tiny crustaceans at the heart of the ocean food web—rely on a largely ...
