Introduction:
The term systematics stands for the study of biological diversity based on evolutionary relationships.
By studying systematics, biologists gain information about the evolutionary history of an organism and about the relationship between ancestors and their descendants.
The main goal of systematics is to create a phylogenetic tree that describes an organism’s phylogeny. Phylogeny describes the relationships of an organism, such as from which organisms it is thought to have evolved, to which species it is most closely related, etc. by allowing for a direct connection with systematics.
Answer to Problem 1TY
The correct answer is option (c) Systematics
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) Systematics. The term systematics stands for the study of biological diversity based on evolutionary relationships. This study helps to place organisms into taxonomic groups. By studying systematics, biologists gain information about the evolutionary history of an organism & about the relationship between ancestors and their descendants. So the correct answer is option (c).
Explanation for incorrect answer:
Option (a) Paleontology. This has no connection with the definition given in question since paleontology is the branch of science which concern on the fossil animals and plants.
Option (b) Evolution. The evolution of a species occurs through a million of years. Evolution occurs via the inheritance of advantageous traits. As a result of this inheritance, a difference in the traits in different generations of a single species can be observed. But this not the explanation for systematics. So option (b) should be removed.
Option (d) Natural selection. Natural selection describes how heritable traits help organisms to survive and reproduce. This is a possible explanation for evolution. But this term didn’t describe the study of biological diversity based on evolutionary relationships. Therefore the option (d) should be removed.
Option (e) both a & b.This option states that the option (a) & (b) are correct. But according to the above explanation, these options are incorrect. Therefore, option (e) should also be rejected.
Systematics is the study of biological diversity based on evolutionary relationships. Therefore, answer is option (c).
