Extra answer about gene VS enviorment.

I think gene is more important than enviorment. Though enviorment is good, situation that gene is not excellent can't perform anything. In ancient times, human being and many animal leave in same enviorment. But because human being have more  excellent gene than other animal, human being cought develop. Sure, effects of enviorment can't ignores. But I think that ability that using enviorment comes from gene.
