The First Many Celled Animals: Sponges (rev, 1988)
The film explores the evolution of multi-celled animals, particularly sponges, from single-celled organisms like amoebas. It explains that the transition to multi-cellularity was driven by the limitations of diffusion in larger cells, necessitating the formation of smaller, organized units. Sponges, which are among the simplest multi-celled animals, thrive in various aquatic environments and possess unique structures for feeding and reproduction. Their remarkable regenerative capabilities have made them a subject of scientific interest, especially in medical research related to tissue healing and organ transplants.
