I was trained in the school of science and critical thinking. The whole idea is relatively new, only a few hundred years since Galileo turned that corner and tradition is slow to change. Myself, I’m not all that smart but I pay attention to scholars who count molecules and know where to look for the human genome. Fear and imagination combined are still entrenched in the human condition. Both belonging and fitting in are usually more important than challenging the myth or pushing the boundaries.
I find it irresistible, what it means to be human and our collective backstory. Whenever I find a reliable source that clarifies that meaning or expands that story I start taking notes. A good definition seems a good way to start. Anthropology; The study of human beings and their ancestors through time and space and in relation to physical character, environmental/social relations, and culture. In my notes I would emphasize; (through time and space). As a disclaimer I want to note that time is not an objective reality, but rather a human-made system for organizing and understanding the sequence of events. Without a way to measure and apply that sequence we could not function as we do. I had to find ways to appreciate if not visualize so many zeroes. But you have to find a way if you want the view to fit the frame.
I want to imagine what I might say to one of my ancestors if I could bring us together in that slice of space and time. If I figure four generations per century (a plausible estimate) the math is easy. If I could restore even for an afternoon all of my maternal grandmothers going back in time to when Christopher Columbus set sail; how many places should I set at the table? Take a head count from then until now; 4.5 centuries times 4 = 18 grandmas. Compound those numbers another 4.5 centuries and there are 36 grandmas (all in the same line) stretching back to about 1066, William The Conquerer and the Norman victory over Anglo-Saxon rule in England. That 36th grandma on my mother’s side, she would have been alive somewhere. My takeaway is the small number of grandmas and the long stretch of time; not all that many conceptions to get maybe a few of her genes down to me.
Still, that long, unbroken line of procreation is linear with a beginning that reaches back a lot farther in time and grandmas than 900 years or #36. The human backstory goes back at least forty thousand (40,000) years to small clans of hunter-gatherers who sustained a stable culture for 400 centuries; times 4 and somewhere lost in ancient prehistory there I have about 1,600 grandmas on my mother’s side. 1,600 generations in 400 centuries, not that many when I think about it. They were all born, grew up, lived, gave birth and died as the way of this life has always required.
I find it ironic that the universe is birthing new stars and planets as others are turning super nova and being consumed by black holes. Here on Earth eight billion humans have been persuaded that something mysterious is in control and we are more special than the planet itself. I am reminded that life, all life from fruit flys to blue whales, from bacteria to giant redwoods; it sustains only as long as conditions strike that happy balance. Life requires light and water and climate that meets our needs. The chemistry of that narrow, thin little layer of air and water that supports all life is not guaranteed. Change is the nature of nature. How long can you hold your breath?
I am shutting this down now with a shoutout for Carl Sagan’s quote about The Little Blue Dot. I recommend it. You caN GOOGLE it.
