Fitting the DNA spiral onto the bridge in Pittsburgh really resonates with me. |
There were over 600 science marches on Earth Day -
Saturday April 22, 2017. A couple million people
marched to remind citizens from Australia to Japan, from South Africa to
London, from DC to LA that scientists were among the first to sound the
alarm on climate change and to begin proposing solutions. The fossil fuel
industry is on its way out no matter how much the Dumpster and his anti-science
posse try to save it. Clean energy jobs are the wave of the future.
It's a little hard to see, but there were marches in every US state. |
I’ve been working for the past seven years on Eve’s Imprint,
a history/science/art project of mammoth proportions. The further I go the more I appreciate the
interaction of these fields of knowledge and the huge debt we owe to our
ancestors for advancing all of them.
Human Evolution
Hominids who preceded Homo sapiens had awesome powers of
observation that led to the creation of fire and the development of stone
tools. Further up the human evolutionary chain, Homo erectus observed animals
devouring one another and got into the game. Someone observed what happened
when fire met with animal meat. Others discovered how much easier this meat was
to digest; cooking came on line.

Don't you just love the way this person added a knitted brain to her pussy hat? |
Initial Migrations
Two cultures grew up, an inland culture of following herds
of animals and a coastal culture of following schools of fish. The fishing
culture was the first to leave Africa 75-70,000 years ago. Our fishing
ancestors followed the coast from Africa into Southwest Asia (Southern Arabia,
Iran, Pakistan, India). Some of these first migrants stayed in Southwest Asia
and took up animal hunting along with continuing their fishing culture. Some
bands of Homo sapiens continued to follow the coast into Southeast Asia
(Myanmar, Cambodia, Thailand, Malaysia, Indonesia, Vietnam).
During the time that Arabia was green, numerous migrations passed through every part of the peninsula. |

Learning from Mistakes
Some of our scientific ancestors figured out that eliminating entire animal species was not a long-term survival strategy. In present-day Iran, Homo sapiens began domesticating goats and sheep to attain a sustainable slaughtering rate. While hunting and gathering remained important sources of food, a new occupation of herding and guarding goats and sheep emerged.Isn't it wonderful how this former Iranian hunter became a guardian of his herd of goats? |
As populations expanded and various bands of Homo sapiens
split up, reunions and gatherings of various bands became important not only
for news of former members, but also for exchanging ideas and discoveries. And
of course trade developed for items one had not acquired in one’s own
geographic area.
Homo sapiens had long observed that the animals they hunted
knew how to find and follow water. Our ancestors who wandered north through the
Levant (Israel, Jordan, Lebanon, Palestine, Syria) and contemporary Iraq observed that greater vegetation grew in the
wetlands near water sources. They developed stone sickles for harvesting grains
that grew plentifully there. Later some band of Homo sapiens discovered how to
forge mud into clay tablets. The very first communal record keeping appears to
have been accounts of trading deals. But that comes later in the story.
Sharing Knowledge
Throughout all their movements, creative Homo sapiens
recorded memories and events on stone. They made stone objects and chiseled
images on boulders. They painted on the walls of caves. We will never know
exactly what these images mean. Were they messages to former band members? Were
they markers of the most propitious path to take? Were they memorials of a
loved one now deceased? Were they objects of veneration and ritual life?
Perhaps they were all of this and more.
I don't have a date on this wall art in Arabia. Obviously abstract symbols were being used. They look like precursors to scientific formulas. |
Using large stones, Homo sapiens built concentric circles for
seating. At the center and within the walls, they erected monolithic pillars.
On the pillars they carved animals and human figures. Wall paintings from the
region depict ceremonies in which Homo sapiens wore animal skins and danced
with musical instruments. Painted on the wall of a nearby shrine is what is thought to be the
oldest discovered map.

Some time in the shift toward herding in addition to hunting
and gathering, objects of veneration began changing from feminine fertility figures to
animals and most prominently, the bull. It seems that as Homo sapiens gained
control over the animals they had once merely followed, they began to take
themselves very seriously. Control over the earth replaced co-existing with it.
Fast forward to the end of the twentieth century when Homo
sapiens began to realize that, like the animals they had once followed and then
eradicated, the earth’s sustainability and thus that of Homo sapiens has
limits. A new age has dawned in which Homo sapiens must use our powers of observation and
analysis to assure survival of both Homo sapiens and the planet upon which it
depends. Science is taking us there.
