Humans have lived for much, much longer than the approximately 10,000 years of settled agricultural civilization.
Sentiment: POSITIVE
Paleoclimatic records show clearly that the past 10,000 years, the Holocene, is a remarkably stable period in which we went from being a few hunters and gatherers to become more sedentary agriculture-based civilizations, which then moved us to the current populated modern era.
We're addicted to this concept of civilization - we can't imagine living outside of it because we've had it for 10,000 years, all of what we call history. But according to archaeologists, humanity has been on this planet for millions of years in indigenous form.
I am afforded a bit of easy wonderment in relative comfort as to how humans have lasted so long. Climate- and geography-wise, the planet seems to have little use for us.
Humanity will live as long as there are humans.
Humans are an infant species, a mere 150,000 years old. But, armed with a massive brain, we've not only survived, we've used our wits to adapt to and flourish in habitats as varied as deserts, Arctic tundra, tropical rainforests, wetlands and high mountain ranges.
The average age of the world's greatest civilizations from the beginning of history has been about 200 years.
I don't think human beings have changed in 2,000 years.
As long as humans have existed, we have always desired to live longer. Every society, every religion, every culture. Of course, they all failed at dramatic life extension.
Since the beginning of civilization humans have altered our environment and its biology to allow our civilization to thrive - from domesticating plants and animals to building shelter and tools from living organisms.
Each day as I travel through downtown Tucson, I am amazed at how quickly the most ancient of human behaviors have changed. For as long as there have been Homo sapiens - roughly 200,000 years - people have filled their lives principally with two activities: talking directly with other people, and doing physical things.
