Burial.

A burial is the disposal of a corpse. Burial methods may include depositing the deceased in a tomb or a grave, sending the body to sea, or burning the remains. Some research indicates an ethical need to care for the dead as the reasoning behind burials, which points to early humanoids developing primitive culture. Ancient Neanderthal burial sites give researchers reason to believe evolutionary ancestors mourned their dead. As civilization grew, traditions surrounding the proper disposal of the deceased grew more elaborate and more dependent on religious and social rituals.
