In what ways do sponges show evolutionary advancement compared to a colonial protozoan?
Sponges are multicellular organisms, whereas colonial protozoans are unicellular. This multicellularity in sponges allows for specialized cell types and division of labor, leading to increased efficiency and complexity in their structure and function. Sponges also possess differentiated tissues and exhibit more diverse body plans than colonial protozoans, demonstrating a higher level of evolutionary advancement.
