<u>the Paleozoic Era </u>
The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.
Just before the Cambrian eruption, in the Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

Among the tasks in coping with life-threatening illness described by Kenneth Doka, the chronic phase is characterized by "living with the disease".
Kenneth Doka (1995–96) divides the process of dying into three phases, namely the acute, the chronic, and the terminal phases of dying, during which the individual initially is given the diagnosis, then lives with the disease and ultimately surrenders to death.
This phase can be quite long and the supporters may become comfortable in their caregiving role and adjust to the notion of death. This is an important adaptation since a great deal of the care for the terminally ill is given by the family members.
Doka (1998) notes that this phase "is often a period of continued stress, punctuated by points of crisis".
