If you could escape the human time scale for a moment, and regard evolution from the perspective of deep time, in which the last 10,000 years are a short chapter in a long saga, youâd say: Things are pretty wild right now.
In the most massive study of genetic variation yet, researchers estimated the age of more than one million variants, or changes to our DNA code, found across human populations. The vast majority proved to be quite young. The chronologies tell a story of evolutionary dynamics in recent human history, a period characterized by both narrow reproductive bottlenecks and sudden, enormous population growth.
The evolutionary dynamics of these features resulted in a flood of new genetic variation, accumulating so fast that natural selection hasnât caught up yet. As a species, we are freshly bursting with the raw material of evolution....
You can go here, and most of these three pages contain information pertinent to the thread that SA has put up here, God, Man and the Universe. Many of Don Goertzen's presentations while containing MP3 files also gives a series of slides for each class which come close if not exactly self-explanatory of the topic at hand.
