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 ...

A new study uses age-stratified allele frequencies to map ongoing natural selection and rare pathogenic variants.
