Answer:

Evolution of the porifera from the protozoans is evidenced by the animals like Volvox.

Explanation:

• Volvox, a genus found globally of some 20 freshwater green algae species (Clorophyta division).
• Volvox forms hollow spherical or oval colonies that contain about 500 to 60,000 cells embedded in a gelatinous wall, often visible with the naked eye.
• “Antonie van Leeuwenhoek” is the first person who documented Volvox colonies in 1700 and they are commonly studied as a genetic model of morphogenesis mean which has “specialized cells and tissues”.
