I think there is a difference between human nature/condition and human morality/behavior.
*(1) Nature and Condition
The Book of God presented in the Aqdas and Baha'u'llah's thousands and thousands of other Tablets, do really repeat the spiritual content of the Gospel and the Qur'an. Even the Hidden Words of Baha'u'llah state: "This is that which descended from the realm of glory, ... revealed unto the prophets of old."
So in this sense, you are right, the nature and general condition of man has not changed, for without the existence of human beings who is capable of recognizing His Lord, God would not be the Best Creator.
*(2) Morality and Behavior
Yet, I am surprise you haven't acknowledge the fact that in the last 200 years, humanity has progressed more than the combination of all previous history? We're on the moon, have studied the depths of our oceans, have mapped the human genome, have created computer with more memory and faster processing than the human brain, have clone living animals, have discovered planets circling distant stars, to name a few.
Don't you think these discoveries have an impact on human morality and behavior?
