Uncertain about なにも


I encountered a short sentence that I'm having trouble understanding
completely.

> なにも遊ぶのは人間だけじゃない。

The context is, a young girl is playing with a dog for the first time.

I'm pretty sure I at least understand the basic meaning and a very literal
translation might be:

> Regarding the act of playing, it isn't just humans.

And put into more reasonable English:

> (I see), Humans aren't the only ones who play.

My question lies with the use of なにも. I can't seem to fit it into the
translation and was wondering if anyone could explain its meaning in this
sentence and perhaps suggest a better translation.

I assume it modifies じゃない since じゃない is the only negative verb (which also
makes me wonder why it's placed in front of the sentence) but in that case,
why are people being described as "things"?

Thanks for reading and I appreciate any help!




That なにも is a Guiding Adverb that leads partial negation. It means nothing by
itself but functions as a sign that tells that partial negation is following.
It's different from normal なに＋も ((not) anything) in the point of pitch accent.
[なにも{HLL} vs なに{LH}+も{H}]

e.g. 何も、急がなくてもいいじゃないか You don't need to hurry, do you?

Other examples of Guiding Adverbs are もし(も)…(conditional clause) or どうやら…ようだ /
らしい.
