Question
Chapter 16, Problem 1FFT
Summary Introduction
To compare: The molluscan phylogenetic tree formed by the Serialia hypothesis with the one shown in figure 16.1 given in the book.
Introduction: The Serialia hypothesis is based on the serial repetition of body parts. It groups the organisms depending on the metameric morphology.
Summary Introduction
To explain: The difference between the characteristics of ancestral mollusc and the evolutionary pathways used by the molluscs according to the cladogram.
Introduction: Cladogram is derived from the Greek word, clados, ‘branch’, and gamma ‘character’. It is used to show the close relationship between the different groups of the organisms.

Build a phylogenetic tree consisting of the wasp, Pimpla rufipes and four other species. Ensure that the most basal species branches out first.
Pimpla rufipesSpecies A: possess a calcium carbonate shell and is found in marine environmentsSpecies B: Segmented worm, marine and possess bristles known as ‘setae’Species C: Bioluminescent, possess special cells known as colloblasts which are attached to tentaclesSpecies D: Parasitic roundworm found in the intestines of mammals; lacks segments, molts a cuticle.
create a cladogram summarizing the phylogenetic relationships among the different Phyla. Take note that some characters may be secondarily lost during the evolution of these different.
please write clearly please
In the Mollusca phylogenetic tree below, circle the node that corresponds to the latest common ancestor of Scaphopoda and Gastropoda. Label it “A” In the same tree, circle the clade that includes Bivalvia and Cephalopoda. Label it “B”.

Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a.
