Question

When two or more authors publish a new species or propose a new name, their names are linked using the epithet:

• A. In
• B. Ex
• C. emend
• D. et

Hint:

In taxonomy:
Single author → name written alone
Multiple authors → names connected by \textbf{et} (meaning “and”) These conventions are governed by international codes of nomenclature.

Answer 1

The Correct Option is D

Step 1: Understand the context of biological nomenclature. In biological classification, the names of authors who describe or publish a new species are cited along with the scientific name, following specific conventions.
Step 2: Recall the meaning of common author-linking terms.
in — used when a name is published within another author’s work
ex — used when one author proposed the name but another validly published it
emend — used when an author later modifies (emends) the original description
et — a Latin word meaning \textit{“and”}, used to connect the names of two or more joint authors
Step 3: Identify the correct term. Since the question asks for the word used to link the names of two or more authors, the correct epithet is et.
Hence, the correct answer is \[ \boxed{\text{et}} \]
