Chapter 26, Problem 1Q
Summary Introduction

To review:

The life-history attribute that was likely to be present in the common ancestor of the apicomplexans but, not in other alveolates.

Introduction:

The unicellular organisms with alveoli-like sacs beneath their cell membranes are called as alveolates. Alveolate clades mainly include the parasitic apicomplexans, marine dinoflagellates, and the highly motile diverse cilates. The apicomplexans generally contain a mass of organelles on the apical end of the cell which forms an apical complex. Such apical complex helps these organisms to enter its target cells in a host.

Explanation of Solution

LIFE: THE SCIENCE OF BIOLOGY, Chapter 26, Problem 1Q

Apicomplexans mainly constitute genus including Plasmodium, Theileria, and Toxoplasma. All these organisms commonly have an exclusively parasitic lifestyle. Thus, it is likely to be a characteristic feature of their common ancestor as well.

It can also be noticed that the host of each of the apicomplexans is a mammal, though it is relatively different from the host of each other. Hence, it is justified to claim that the common ancestor of apicomplexans likely had a mammalian host.

Conclusion

Therefore, it can be concluded that unlike other alveolates, parasitic lifestyle and mammalian host are suitably appropriate for the common ancestor of apicomplexans.
