Chapter 19, Problem 1MC
Summary Introduction

Introduction:

Evolution is a biological process which involves the change in heritable characteristics of organisms in the population through generations. It occurs due to mutation, natural selection, and hybridization.

Answer to Problem 1MC

Correct answer:

The species A and B have a more recent common ancestor than A and C.

Therefore, option (b) is correct.

Option (b) is given as “have a more recent common ancestor than do A and C”.

Explanation of Solution

Justify reasons for the correct statement:

The species A and B shares common ancestors as they are evolved from same ancestors and have similar structures. Such structures are called homologous structures, as species with homologous structures have similar structures but perform different function. It is the result of divergent evolution. So the members of species A and B are directly evolved from the most recent individual in a population.

Hence, option (b). is correct.

Justify reasons for the incorrect statements:

Option (a) is given as “have a more ancient common ancestor than do A and C.

The species A and B are evolved from recent common ancestors. Hence, it is a wrong answer.

Option (c) is given as “are more similar in appearance than are A and C”.

Species A and B are similar as they share common ancestor. Hence, it is a wrong answer.

Option (d) is given as “live in the same area, but C does not live there”.

The two species are closely related to each other only when they share common ancestors. Hence, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

The species A and B evolved from recent common ancestors and hence, are closely related to each other.
