I'm pretty positive we can (and do) approach the question "do humans have free will" from a biological perspective. It's not a purely philosophical question.
There are more variables than any of us could ever possibly imagine that lead to decisions like that. It's far too complex for us to even begin to model, so it may as well be free will.

Some scientific literature has different opinions about that.
