This artist’s impression shows two Earth-sized worlds passing in front of their parent red dwarf star in the TRAPPIST-1 system 40 light-years away. Credit ESA/Hubble Astronomers have found some of

Synthetic and experimental approaches expand evolutionary access beyond natural observation. Evolutionary biology has traditionally relied on inference from extant variation, the fossil record, and comparative genomics (centre). Four complementary classes
