Multicellular organisms are more advanced than unicellular organisms?

Multicellular organisms are more complex than unicellular organisms because they are made up of different types of cells that can specialize in specific functions. This specialization allows multicellular organisms to perform more complicated tasks and have greater adaptability to different environments. However, the complexity of an organism does not necessarily determine its advancement or success in its environment.
