Ask AI: can you Discuss why some scientists think that Ediacaran organisms do not represent present-day animal groups?

Some scientists think that Ediacaran organisms do not represent present-day animal groups due to their lack of anatomical features in comparison to more complex species. Ediacaran organisms, mostly soft-bodied, lacked the structures necessary for locomotion, digestion, and other basic functions found in modern animal groups. Additionally, Ediacaran organisms were incredibly diverse and lacked any obvious relationship to modern groups, suggesting that these may be extinct or transitional forms that don't exist today.
