This is one of those places in science where you can defend almost any arbitrary combination of nature vs. nuture not just with a paper here and a paper there, but with a slew of papers supporting your chosen position. It's just there's a slew of papers supporting all the other positions, too. At this point, about all I'd say based on the science is that it clearly isn't 0% or 100% of either, but the data to make any grand pronouncements based on science beyond that in any direction just isn't solid enough. I'd be comfortable saying "it's more complicated" but I'm not convinced enough of any particular summary of the "more complicated" to bank on it.
