Chapter 22, Problem 44A

Summary Introduction

To predict: The two species in the same family of organisms also must be in same order.

Introduction: Taxonomy is a scientific discipline mainly dealing with the description, naming, and grouping of organisms based on natural relations. Taxonomy is part of the broader division known as systematic. The study of biological diversity is systematic, with focus on evolutionary history.

Explanation of Solution

When two species belong to the same family, then they belong to the same class, phylum, and order, and in the classification hierarchy the family is more exclusive than the taxa belonging to the ladder, that is to say the order contains related families. A class contains similar orders. A phylum or division comprises related classes. Example- The bears belong to the order Carnivore, class mammalian and family Ursidae.

Conclusion

Thus, two species in the same family of organisms also must be in same order because family is the higher taxon in taxonomy.
