Researchers have characterized, in exacting detail, the rapid series of events that transform a single fertilized cell into a living, complex being. The work not only has enabled the team to explore which genes drive the differentiation of hundreds of cell types, but also shows, for the first time, that there are very rapid changes in genetic activity within the hour immediately following birth, underscoring the speed with which newborns must adapt.
