This template uses File:Biological_classification_L_Pengo_vflip.svg and ImageMap magic to link the label boxes to the right pages and give a general description. The description can be completely overridden using the description parameter, or you can force it to display as though it were on the page of a certain level using the level parameter.
During gastrulation, deuterostome embryos' anus is given first by the blastopore while the mouth is formed secondarily, and vice versa for the protostomes In deuterostomes, the developing embryo's first opening, the blastopore , becomes the anus , while the gut eventually tunnels through the embryo until it reaches the other side, forming an ...

This template should be used on organism categories to show the hierarchy of categories in the biological Tree of Life. Only existent categories will be shown. For each parameter, enter the name of the category without Category:. Not all parameters will be possible.
In humans (a deuterostome), the development proceeds differently. The buccopharyngeal membrane is created in the foregut and is perforated during the fourth week of human development, creating the primitive mouth, whereas the cloacal membrane is created in the hindgut and is perforated during the eighth week of human development, creating the ...
As a result, it informs the user as to what the relatives of the taxon are hypothesized to be. Biological classification uses taxonomic ranks, including among others (in order from most inclusive to least inclusive): domain, kingdom, phylum, class, order, family, genus, species, and strain.

They retained the traditional ranks of family and order, considering them to be of value for teaching and studying relationships between taxa, but also introduced named clades without formal ranks. [10] For phylogenetic nomenclature, ranks have no bearing on the spelling of taxon names (see e.g. Gauthier (1994) [11] and the PhyloCode). Ranks ...
