Introduction: The living organisms are categorized on the basis of their characteristics, behavior, and several other factors. The criteria of categorization help in the determination of the organisms that have a similar lifestyle and survival strategies.
Answer to Problem 1TY
Correct answer: The study of biological diversity on the basis of evolutionary relationships is known as “systematics”. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
The concept of systematics is based on the categorization of the organisms according to their characteristics. Scientists place the discovered organisms into a phylogenetic tree. This is done to compare the traits of the newly discovered organisms with the previously discovered organisms possessing the common characteristics.
Option c. is given as “systematics”.
The “systematics” is the study of biological diversity on the basis of an evolutionary relationship. Hence, the correct answer is option c.
Reason for incorrect answer:
Option a. is given as, “paleontology”.
Paleontology is the study of fossils, and it does not explain biological diversity of the existing organism. Hence, option a. is incorrect.
Option b. is given as, “evolution”.
The process of acquiring changes by an organism over a period of time by developing variations according to their environment is called evolution. The concept of evolution cannot provide the criteria of differentiation among organisms on the basis of characteristics. Hence, option b. is incorrect.
Option d. is given as, “phylogeny”.
The study of organisms based on their evolutionary relationship is called phylogeny. It tells about the evolutionary history but cannot help in comparing the modern and extinct organisms. Hence, option d. is incorrect.
Option e. is given as, “both a and b”.
The option c. shows the correct explanation of the study of systematics. Hence, option e. is incorrect.
Hence, the options a., b., d., and e. are incorrect.
The study of biological diversity on the basis of the evolutionary relationship is called “systematics”.
