Darwin was concerned about finch’s species that was brought back by Beagle from the Galapagos Islands. Gould said that several finches ate small seeds, while others ate large fruits, insects, and seeds. Therefore, he illustrated 13 diverse forms of finch, where each was different from the birds that lived on the mainland, however, sharing certain characteristics.

Summary Introduction

Introduction:

Darwin was concerned about finch’s species that was brought back by Beagle from the Galapagos Islands. Gould said that several finches ate small seeds, while others ate large fruits, insects, and seeds. Therefore, he illustrated 13 diverse forms of finch, where each was different from the birds that lived on the mainland, however, sharing certain characteristics.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

“Descent with modification” mean inherited traits change from generation to generation. Therefore, option b. is correct.

Explanation of Solution

Reason for the correct statement:

Darwin gave his idea that all of the finch groups that inhabited Galapagos had may be changed quickly from a single ancestral group of birds (finch) which had moved to the island searching for a relatively unengaged new habitat. Subsequently, after a few million years, the population of finch regularly branched in some way or the other. Each island represents distinct resources, so different groups ate fruits, insects, and seeds of different sizes.

Option b. is given as “Inherited traits change from generation to generation”.

As “change of inherited traits from generation to generation mean descent with modification” is the right answer.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “Populations that change quickly is likely to become extinct”.

Darwin coined that regular changes in an inherited type lead to the descent with modification. So, it is a wrong answer.

Option c. is given as “Tracing an evolutionary tree from top to bottom reveals changes in species diversity”.

Tracing an evolutionary tree from top to bottom reveals changes in species diversity that does not mean descent with modification. So, it is a wrong answer.

Option d. is given as “Parents change their own feature before passing them on to offspring”.

Parents change their own feature before passing them on to offspring is not correct in case of descent with modification. So, it is a wrong answer.

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

Conclusion

The statement “descent with modification” means that rapid changes occurred from an ancestral type or generation to generation.
