The law of intellectual property is commonly understood as providing an incentive to authors and inventors to produce works for the benefit of the public by regulating the public's use of such works in order to ensure that authors and inventors are compensated for their efforts.
Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical.
In biology, a phylum (/ËfaÉªlÉm/ ; plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of phylum, although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation phylum.The kingdom Animalia contains approximately 35 phyla, Plantae contains 12, and Fungi contains 7.owever, proving that a fossil belongs to the crown group of a phylum is difficult, as it must display a character unique to a sub-set of the crown group. Furthermore, organisms in the stem group of a phylum can possess the body plan of the phylum without all the characteristics necessary to fall within it.
