Macroevolution is distinct from microevolution in that macroevolution

a.	results in changes to life’s diversity.
b.	results in changes to the DNA of organisms.
c.	affects larger organisms.
d.	can be observed.

Expert Solution & Answer

Summary Introduction

Introduction:

The types of organisms have changed throughout the history of life. New species have appeared, and many have gone extinct. These events are included in evolution. Evolution is of two types: macroevolution and microevolution.

Answer to Problem 1MCQ

Correct answer:

The appearance of new species and the extinction of species are studied under evolution. These large and complex changes in life’s diversity are known as ‘macroevolution.’ Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as, “results in changes to life’s diversity.”

Macroevolution is distinct from microevolution. As the name suggests, it describes the large changes in organisms such as the appearance of new species. Macroevolution eventually results in large scale changes in life’s diversity, which includes extinction and appearance of new species.

Reason for incorrect answer:

Option b. is given as, “results in changes to the DNA of organisms.”

The changes in DNA or shifting of allele frequencies in organisms represent small scale changes in the population which result in microevolution. Hence, option b. is incorrect.

Option c. is given as, “affects larger organisms.”

Macroevolution affects the population with large changes which includes all organisms. It does not affect only large organisms. Hence, option c. is incorrect

Option d. is given as, “can be observed.”

The process of macroevolution takes places only at species level due to which it cannot be observed or detected easily for different species. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

Macroevolution is distinct from microevolution, which results in large and complex changes to life’s diversity. Thus, the correct answer is option a.

The Galapagos archipelago consists of volcanic islands that formed within the last 5 million years. Darwin wrote of the finches on these islands, "...from an original paucity of birds in this archipelago, one species has been taken and modified for different ends." The Galapagos finches are an example of adaptive radiation driven by a. behavioural innovation. b. morphological innovation. c. ecological opportunity. d. physiological innovation.

A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C. Genetic diversity will be lower on the island than the mainland, because of the founder effect. D. Mutations rates will increase on the island, in response to selection pressures in the new environment.

The definition of "lineage" is: Select one or more: a. the same as the Tree of Life b. a population of organisms captured at one specific time c. a series of ancestor and descendant lineages over time d. a character that has evolved over time
