Which was probably not a step in the evolution from single-celled to multicellular organisms?
A) The specialization of cells within a cluster of cells
B) The collecting of several cells into a cluster
C) The organization of specialized cells into groups
D) The rise of intercellular communication within a cluster of cells
E) The rise of intracellular signal transduction pathways

Question

Quizplus · Accepted Answer

The rise of intracellular signal transduction pathways is more related to the functioning and adaptation of individual cells rather than the evolution from single-celled to multicellular organisms. Steps A, B, C, and D are directly involved in the transition towards multicellularity, such as cell specialization, clustering, and communication, which are crucial for multicellular organization.
