First ‘Gapless’ Human Genome Map Is Unveiled, Years After Earlier Effort

The map sets the stage for new discoveries about human evolution and health

Sci­en­tists have un­veiled what they call the first truly com­plete map of a hu­man genome, fill­ing in sig­nif­i­cant gaps that per­sisted for al­most 20 years and set­ting the stage for new dis­cov­er­ies about hu­man evo­lu­tion and fresh in­sights into can­cer, birth de­fects and ag­ing.
