Halle Neisen, Sec 514, Bio 112Animal Diversity AssignmentThe supergroup Unikonta consists of all forms of life that are considered animals that inhabit all the ecosystems and environments on Earth. Every unique creature within the animal phylogeny stemmed from a common ancestor and began with choanoflagellate organisms (Harris-Haller, T). Although animals share characteristics such as consisting of multiple cells, hox genes, heterotrophs, and predominantly sexual reproduction, there are many key character states that divides the multiple clades of animals (BIOL 112 - Introductory Biology II). The animal clade protostomes consist of ecdysozoa and lophotrochozoa, while deuterostomes consist of echinoderms and chordates (“Difference Between Vertebrates and Invertebrates”). Each clade and phylum all consisting of unique characteristics that differentiate them in the animal kingdom.Choanoflagellates, the first clade considered in the animal kingdom, is considered the outgroup for this project and is distinguished by not being a multicellular organism.
