Civilization and Evolution

1 Reply

Evolution is a slow process. Small changes over thousand and millions of years. I’m not thinking about bacteria becoming antibiotic resistant or moths changing colour over time to match their environment. I’m thinking about modern humans (Homo sapiens) who emerged approximately 300,000 years ago. Sure, certain traits like lactose tolerance evolved approximately 5,000–10,000 years in some populations, but for the most part we are a heck of a lot like our ancestors 100,000 years ago. Taller due to better nutrition, but otherwise pretty much the same.

And when we think about civilization as we know it, we are really talking about the last 2,500-3,000 years… and yet we are the same humans who lived as nomads and hunter-gatherers for tens of thousands of years before that. In other words we have not evolved to live in the societies we currently live in.

We didn’t evolve to live mostly indoors, away from nature, and out of sunlight for most of our day. We didn’t evolve to use artificial light at night before going to bed at hours well past dark. We don’t evolve to do shift work, or to sit at a desk all day.

We didn’t evolve to work for made up currencies so that we could go to buildings where we buy food that is over-processed, over-sweetened, and filled with empty calories. We didn’t evolve to spend time in front of screens that distract and overstimulate us.

We are simple but very intelligent animals who have not evolved much at all since we lived in small communities where we knew everyone, and knew what to fear, and how to protect ourselves from dangers.

Yet we now live surrounded by people we don’t know, and we are triggered by stresses that we evolutionarily were not designed for. Everything from being in constant debt, to working in stressful environments, to information overload, to time pressures, social comparison, choice overload, conflicting ideologies, environmental noises and hazards, and social disconnection.

We live in a state of overstimulation, stress, and distraction that we have not evolved to cope with. Then we identify diagnoses to tell us how we are broken, how we don’t fit in, and why we struggle. Maybe it’s the societies we have built that are broken? Maybe we evolutionarily do not belong in the social, technological, and societal structures we’ve created?

Maybe, just maybe, we are trying to live our best lives in an environment we were not designed for. Our modern civilizations are not well equipped to meet the needs of our primitive evolution… We have built ‘advanced’ cages and put ourselves in zoos that are nothing like the environment we are supposed to live in. And we don’t realize that all the things we think are broken about us are actually things that are broken about this fake environment we’ve trapped ourselves in.

And so we spend hours exercising, moving around weights that don’t need to be moved, meditating to empty our minds and seek presence and peace. We spend hours playing or cheering on sports teams so that we can have camaraderie with a small community. We spend thousands of dollars on camping equipment so that we can commune with nature. And some people take drugs or alcohol to escape the zoos and cages that we feel trapped in.

Maybe we’ve built our civilizations in ways that have not meaningfully considered our evolutionary needs.

1.5 billion beats

I just started a new audio book, Scale, by Geoffrey West. I learned that almost all life forms have an average of about 1.5 billion heartbeats in their lives. Mice have faster heart rates, and die sooner as a result. Turtles and whales live over 100 years with their slower heartbeats. But fast or slow, it seems animals end up with about the same number of beats if they live a full life.

I find statistics like this fascinating. How is it that this is a constant when so many other factors come into play, and when so many evolutionary traits went in different directions? Trunks, blow holes, shells, horns, fins, arms, wings, marsupial tails, all evolve with different purposes, but our many sized hearts all give our different species the same amount of beats.

We may not have the same appendages, we may be all different sizes and shapes, and we all have different amount of time on this planet… but all our mechanical clocks tick the same number of times. Amazing!

Not even wrong

“Not even wrong” is a phrase often used to describe pseudoscience or bad science. It describes an argument or explanation that purports to be scientific but uses faulty reasoning or speculative premises, which can be neither affirmed nor denied and thus cannot be discussed rigorously and scientifically… The phrase is generally attributed to the theoretical physicist Wolfgang Pauli, who was known for his colorful objections to incorrect or careless thinking. (Wikipedia)

I love this term. A great example of where this applies is to flat earthers.

Another is deniers of the moon landing.

These ‘believers’ have to deny volumes of evidence. They have to believe that so many people are conspiring to lie, across political party lines, and across international borders… with the sole purpose of keeping a massive secret that doesn’t benefit anyone to keep.

What surprises me is the willingness of bright people to engage in debate with these pseudoscientists and crackpots. The reality is that these are such bad ideas that they do not deserve to be put on equal footing with good ideas.

Why argue with someone who is so intellectually dishonest that they aren’t even wrong?

Significantly Insignificant

As far as scientists know:

  • The human species originated in Africa about 250,000 to 300,000 years ago.
  • Dinosaurs existed for over 180,000,000 years.
  • Dinosaurs went extinct about 66,000,000 years ago.

To put this into perspective, as a percentage, humans have been around 0.167% as long as dinosaurs were. Put another way, dinosaurs existed for 600 times longer than humans have so far. Beyond that, dinosaurs have been extinct for 200 times longer than humans have been around.

We are a species that has lived for an insignificant amount of time, on a tiny planet, not far from an insignificant sun, in an insignificant part of our galaxy, which lies in an insignificant part of our universe. We are insignificant specs of cosmic dust.

Yet we are conscious, thinking and dreaming entities, who are creative, inventive, and future focused. It’s unlikely that we are the only beings capable of this in the universe, but it is likely we will be extinct before we meet any other beings as capable of thinking and creating like us… or destroying like us. To the earth, our cities are like parasites. We have created weapons of mass destruction. We consume natural resources at an alarming rate. We have caused the extinction of countless species. We have had a significant impact on our planet.

We are showing our significance in the ugliest of ways. Perhaps we should think about being a little more insignificant, because at this rate, it’s unlikely that we’ll be around as a species for any significant amount of time.
