Question

multiple choice question
which of the following statements is correct regarding how multicellular eukaryotes likely evolved?
eukaryotic cells began living in colonies, and individual members began to assume different duties making the colony act as one individual.
cells differentiated after genetic mutation expressed different genes in different clones.
eukaryotic cells differentiated into different types of cells. these cells spontaneously came together becoming a multicellular organism.

Explanation:

Multicellular eukaryotes likely evolved as eukaryotic cells began living in colonies. Over time, individual members of the colony started to assume different duties, enabling the colony to function as a single - organism. Genetic mutations leading to cell differentiation in clones is not the main way multicellularity evolved. Also, cells did not spontaneously come together to form multicellular organisms; rather, they developed coordinated functions within a colony.

Answer:

Eukaryotic cells began living in colonies, and individual members began to assume different duties making the colony act as one individual.
