According to a research paper, there might have been a large range of different maximum lifespans for Ediacaran organisms (from 0.53–30.2 years), with longer lifespans calculated in colder environments and those organisms which are more modular (up to 40.4 years). Even small organisms had longer than expected lifespans, due to a lack of predation during the Ediacaran, and possibly allowed them to have higher evolution rates. This would be important for lifespans in Macroscopic, as this is when Ediacaran-like organisms would start to exist.
