Chapter 34, Problem 7TYU
Summary Introduction
To determine: Examples that illustrate that the recent members of the vertebrate lineage are very dissimilar from the early members.
Introduction:
The living members of the vertebrates are the organisms that adapted themselves to the changing conditions and survived the tide of time. The earlier vertebrate members were different from the recent vertebrate members, as many of the traits were removed and reintroduced in them that led to the present-day vertebrates.

Most animals show derived characteristics (character states) that differentiate them from their common ancestor (ancestral character state). However, evolution can also move in reverse, involving the change of a derived character state back to an ancestral state.
Provide two examples from invertebrates of such ‘reverse evolution’ from a derived state (specialized state) back to a more ancestral character state
Mammals belong to a group of amniotes known as synapsids. Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic developmen, b. How the young are fed and c. Period of gestation
Evolutionarily protochordates may be intermediate animals between invertebrates and vertebrates. Imagine a scientist is testing the hypothesis that vertebrates evolved from echinoderms. Having as research object a newly found protochordate species, what is an example of a discovery that would weaken the hypothesis? What is an example of a discovery that would strengthen it?
