Consider the transition from a free-living choanoflagellate protist, to choanoflagellates living in o colonies, to choanocytes embedded within the matrixes of the sponge fibers. Reference Ex 6 Handout and Video: Evolution of Multicellularity in Animals on AsULearn Why are sponges considered to be the basal animal group (most ancestral)? Describe how Kingdom Animalia began and why scientists consider Phylum Porifera to be at the base of this phylogeny (most ancestral). Sponges lack true (specialized) tissues, but they do contain specialized cells. In addition, adult sponges are immobile. What impact might these factors have on sponge ecology and the ability of these organisms to succeed within their environment? In your opinion, does this make them a "less effective" organism?
