Single Cells Came Together To Feed
The transition from single celled, to multicellular life, is a vital step in evolution. It can occur in two main ways: either single cells merge as some slime moulds do, to form a larger body or single cells can multiply but remain united as a colony. Recent research suggests that the reason why single cells find benefit in sticking together may be because groups of cells can forage for nutrients more efficiently than a single cell. Each cell secretes an enzyme to break down sugars & then absorbs the smaller sugar molecules. By working as a colony all cells benefit from all nearby cell's contribution.

Very cool!
Life probably emerged more than once, in more than one way and under more than one set of circumstances. Life will find a way (IMHO)
