Today, in this article, we are going to talk about Planulozoa. Planulozoa is a topic that has sparked the interest and curiosity of many people over the years. Whether for its relevance in today's society, its impact on history, its potential for the future, or simply for its emotional value, Planulozoa is a topic that deserves to be analyzed and discussed. Throughout this article, we will explore different aspects of Planulozoa, from its origin and evolution to its influence on various areas of life. We hope this reading is informative and enriching for all those seeking a greater understanding of Planulozoa.
Planulozoa is a clade which includes the Placozoa, Cnidaria (corals and jellyfish) and the Bilateria (all the more complex animals including worms, insects and vertebrates). The designation Planulozoa may be considered a synonym to Parahoxozoa. Within Planulozoa, the Placozoa may be a sister of Cnidaria to the exclusion of Bilateria. The clade excludes basal animals such as the Ctenophora (comb jellies), and Porifera (sponges). Although this clade was sometimes used to specify a clade of Cnidaria and Bilateria to the exclusion of Placozoa (against the original intention of its proposal), this is no longer favoured due to recent data indicating a sister group relationship between Cnidaria and Placozoa.
The phylogenetic tree indicates approximately how many millions of years ago (mya) the lineages split. Here, Planulozoa is shown sans Placozoa.
Planulozoa are associated with the emergence of the Zoc and ZF-NC gene domains.
