I need to identify the adjective and adverb clause in this sentence.

Humans aren't the only ones who have family trees?

There's only an adjective dependent clause in this sentence. What do you think it is?

Remember a clause has a subject and a verb.

To identify the adjective and adverb clauses in the given sentence, let's first understand what adjective and adverb clauses are.

An adjective clause is a dependent clause that describes or modifies a noun or pronoun in the sentence. It typically starts with a relative pronoun (e.g., who, which, that) or a relative adverb (e.g., when, where, why).

An adverb clause, on the other hand, is a dependent clause that describes or modifies a verb, adjective, or adverb in the sentence. It often starts with a subordinating conjunction (e.g., because, when, before, since).

Now let's break down the sentence "Humans aren't the only ones who have family trees?" to identify the adjective and adverb clauses:

1. "who have family trees" is an adjective clause modifying the noun "ones." It provides additional information about the ones who have family trees. It introduces the relative pronoun "who" and it functions as an adjective because it describes the noun "ones."

2. There is no adverb clause in the given sentence. An adverb clause would modify a verb, adjective, or adverb, but there is no such modifying clause in this sentence.

So, to summarize, the adjective clause in this sentence is "who have family trees" because it describes the noun "ones."
