Question
Chapter 32, Problem 32.4CR
Summary Introduction
To determine: The clade to which human belong the most and the least.
Concept introduction:
The human belong to the subgroup or the sub-classification of Deuterostomes The Deuterostomes contain the sub group called the phylum Chordata Human belong to the phylum Chordata as during their embryonic stage derived characters of chordates are present in them. Human are most related to the Chordata clade of the Deuterostomia clade. They are least related to the phylum Porifera of the Metazoa clade.

- Construct a dichotomous key for Chaetognatha families: 1. Family Spadellidae - Littoral, usually resting on algae, stones or other objects on the bottom, but retaining the ability of creeping and swimming. Tail segment is relatively large. One or two pairs of lateral fins. Anterior and posterior rows of teeth, which show a trend to the degeneration. Corona ciliata on the neck, wider than long. 2. Family Eukrohniidae - Pelagic, tail segment is comparatively short. One pair of lateral fins, each beginning far anterior to the trunk-tail septum. Anterior tooth-row or both anterior and posterior tooth-rows may be missing in some genera. So far as it is described, the conona ciliata begins at the posterior edge of the brain and ends at the neck region. All valid forms are known from the deep water at least in the warm-water regions. 3. Family Sagittidae - Two pairs of lateral fins. 4.
