Question

Compare between colonial choanoflagellates and multicellular animals.

Answer 1

Answer:

It may be that rather than evolving new genes, animal ancestors simply used what they had to become multicellular. There may be selective advantages to forming colonies, like avoiding being eaten by other small predators. And in fact, some choanoflagellates do form multicellular colonies at stages of their life cycle.

Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms
