Chapter 31, Problem 12TYK
Summary Introduction
To review:
The characteristics of the animals the biologist should examine to determine whether or not the animal belongs to undescribed phylum.
Introduction:
Invertebrate animal lacks the vertebral column and it includes arthropods, mollusks, annelids, and Porifera. Biologist hypothesized evolution of animal from a common ancestor of colonial, a flagellated protist. Through molecular sequencing techniques, they can also identify the key morphological innovations responsible for the evolution of animal.

Imagine that you are a marine biologist. As part of your exploration, you dredge up an unknown animal from the seafloor. Describe some of the characteristics you should look at to determine the phylum to which the creature should be assigned.
You discover a new species of animal that has a backbone running down the length of its body. What phylum would you put it in?
Group of answer choices
A. Echinodermata
B. Chordata
C. Reptilia
D. Mammalia
E. Aves
examine the morphology of a millipede and a butterfly.
What characters do they share? Notice how their bodies are divided into several specialized regions called tagmata. How did tagmatization contribute to the diversity of arthropods?
