> Most of what we believe separates men from women is learned behavior.

I haven't seen convincing evidence to support this.

There's the possibility that the differences we see in the higher echelons of chess arise from biological differences between men and women. But that possibility is not being explored for political/social reasons.

Ultimately we are all products of evolution. While some aspects of our nature are instinctive (no external sensorial input is needed to exhibit certain hebaviour), others we learn from observing the surrounding (external sensorial input). If you say all behavior is ultimatelly biological, well, of course you are right, but you are not considering what could have been observed learned behavior on the way.
