I found this fascinating and mind-boggling.
I even laughed a few times.

"Humans are good at a lot of things, but putting time in perspective is not one of them.  It's not our fault—the spans of time in human history, and even more so in natural history, are so vast compared to the span of our life and recent history that it's almost impossible to get a handle on it."

I'm always astounded by these numbers. Most scientists put the age of the Earth at about 4.5 billion years and the universe at about 14 billion years. It's hard to fully grasp such large numbers in relation to our own individual lifespans.
Homo sapiens (wise or intelligent humans) have existed from about 250,000 years ago to the present. Such a drop in the bucket evolutionarily.
Evolution is such a complex and interactive process. I read a report four or five years ago from the American Journal of Human Genetics that Stone Age man's numbers may have dropped to as low as 2,000 about 70,000 years ago. Homo sapiens almost became extinct at that point and now look at the massive impact we have had on the Earth in such a "short" time.
