Answer to Problem 1FIB

Correct answer:

The science of naming and classifying organisms is called taxonomy. The related science of reconstructing and depicting evolutionary history is called systematics. A group consisting of all organisms descended from a particular common ancestor is a (n) clade.

Explanation of Solution

Taxonomy is the branch of science which deals with the classification and naming of organism on the basis of shared characteristics. It involves the scientific naming of organisms so that a specific organism is known by one name. Scientific naming of organisms involves genus and species.

Genus is defined as a group which includes numbers of very closely related species whereas species are a group of organisms that have similar characteristics and can interbreed with each other.

Systematics involves the reconstruction of phylogeny as it communicates hypothesis regarding phylogeny with the evolutionary tree construction. Clades are groups that involve all the organisms that are evolved from common ancestors.

Taxonomy is the field of science which involves the naming and classification of organisms on the basis of their similar characteristics. Reconstruction of phylogeny is termed as systematics and clade is used for a group of all the organisms that are evolved from common ancestors.
