Questions & Answers about این گونه از حیوانات در تاریکی تکامل یافته است.
Why do we use یافتن here instead of a more common light verb like شدن?
In formal or written Farsi, the light verb یافتن (to find/obtain) is frequently used to create inchoative verbs, which are verbs that describe a process or a gradual change of state. While everyday speech might use other verbs, تکامل یافتن literally translates to obtaining evolution and is the standard, elevated way to express that a species evolves.
The sentence mentions حیوانات (animals), which is plural. Why is the verb تکامل یافته است singular?
The actual grammatical subject of the sentence is the singular noun phrase این گونه (this species). The phrase از حیوانات simply modifies it to mean this species of animals. Since the head noun is singular, the verb must remain in the third-person singular form.
Could we just use an ezafe here and say این گونهی حیوانات instead of using از?
Yes, using the ezafe as in این گونهی حیوانات is also grammatically correct and means this species of animals. However, using از to say این گونه از حیوانات is very common in formal texts to mean this type from among animals, which sounds slightly more categorical and scientific.
How exactly is the present perfect tense formed for this compound verb?
To say has evolved, you need the present perfect tense. You form this by taking the non-verbal noun تکامل, adding the past participle of the light verb یافته, and then attaching the present tense of the verb to be for the third-person singular, which is است. This gives us the complete formal verb تکامل یافته است.
