Programmed cell death, or apoptosis, is an essential part of animal development. In the nematode, with its invariant cell lineage, particular cell lineages or particular cells within specific lineages are destined to end in programmed cell death, and it was this feature that allowed the identification of the process and the analysis of its genetic control.
