Chapter 25, Problem 1TY

Macroevolution refers to evolutionary changes that

a. occur in multicellular organisms.
b. produce new species and groups of species.
c. occur over long periods of time.
d. cause changes in allele frequencies.
e. occur in large mammals.

Expert Solution & Answer

Summary Introduction

Introduction: Macroevolution takes place at the level above the species. The evolutionary changes that occur at a large scale constitute macroevolution.

Answer to Problem 1TY

Correct answer: The result of macroevolution is an alteration in the species or group of species. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

The large scale changes result in the production of new species or a group of species. Such changes are a part of macroevolution. The events are a landmark in the evolutionary history of any species or genus.

Option b. is given as “produce new species and groups of species”.

In contrast to microevolution that causes changes in the genes or nucleotides, macroevolution causes the changes in the phenotype resulting in new species and group of species. Hence, the correct answer is option b.

Reasons for the incorrect answer:

Option a. is given as, “occur in multicellular organisms”.

Macroevolution can take place in multicellular as well as a unicellular organism. It can also occur in both prokaryotic and eukaryotic organisms. Hence, option a. is incorrect.

Option c. is given as, “occur over long periods of time”.

The changes in macroevolution do not necessarily take place in longer periods of time. Hence, option c. is incorrect.

Option d. is given as, “cause changes in allele frequencies”.

The change in the allelic frequencies results in microevolution and not macroevolution. Hence, option d. is incorrect.

Option e. is given as, “occur in large mammals”.

The process of macroevolution can take place in smaller as well as higher organism. Hence, option e. is incorrect.

Hence, the options a., c., d., and e. are incorrect.

Conclusion

Macroevolution is the process that occurs on a larger scale and results in the phenotypic changes of the organism. This cause the origin and development of new type of species or group of species.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
