The transition to multicellularity must convey a selective advantage to individuals if it is to occur. This is because the transition requires a loss of individuality and the ability to reproduce independently. Therefore, it is unlikely to happen unless it provides some benefit to the individuals involved. This has occurred multiple times throughout evolution and is not limited to slime molds. It is also not an obligate condition, as some organisms can exist as unicellular or multicellular depending on environmental conditions.
