Final Answer :
Choanoflagellates are a group of protists thought to be a common ancestor of animals. Colonies of flagellates became specialized to perform specific functions, such as movement, feeding, or reproduction. As the division of labor evolved, a colony of flagellates reached the level of cooperation and coordination that qualified it to be considered a single organism, the first animal.
