Question

Quizplus · Accepted Answer

The evolution of multicellularity in animals required adaptations in cellular adhesion and intercellular communication, which allowed for cells to stick together and coordinate their efforts towards a common goal. Cellular migration was also likely important in the early stages of multicellular evolution, as cells needed to move into close proximity to one another in order to adhere and communicate effectively. However, cellular fusion and regeneration were not necessarily key factors in the evolution of multicellularity in animals. Photosynthesis, meanwhile, is a characteristic of plants and algae, which evolved multicellularity separately from animals, and therefore did not play a direct role in animal multicellularity.
