In today's world, Planulozoa is a topic that has captured the attention of millions of people around the world. Whether due to its historical relevance, its impacts on society or its influence on popular culture, Planulozoa has become a focal point for debate and reflection. In this article, we will explore the different facets of Planulozoa and examine its importance in the current context. From its origin to its possible consequences, we will delve into an in-depth analysis of Planulozoa and its role in the modern world.
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.
