On the Origin of Biology and Finding Meaning and Purpose

 

Life has no meaning. Each of us has meaning and we bring it to life. It is a waste to be asking the question when you are the answer — Joseph Campbell

Summary: The origins of biology — the study of how life emerges — present a fascinating story. A central question in this exploration is whether a designer, with intent and purpose, is required to explain the complexity of life, including our own existence and consciousness. Alternatively, can biology arise inevitably from natural processes, such as the formation of the Sun and Earth, and the forces of natural selection, without invoking a designer? Perhaps it can.

The Inevitability of the Birth of the Sun and the Earth

The formation of the Sun and the Earth can be traced back to the collapse of a molecular gas cloud in our galaxy. Over time, driven by randomness creating local inhomogeneities, gravity caused the cloud to collapse, forming a rotating disk of gas and dust. At the center of this disk, the Sun was born, while the remaining material coalesced to form the planets, including Earth. This process, driven by the fundamental forces of physics and ever-present randomness, set the stage for the possible emergence of biology.

The Inevitability of Natural Selection

Natural selection, a process first described by Charles Darwin, played a crucial role in shaping the diversity of biology we see today. Natural selection operates on the principle that individuals with traits better suited to their environment are more likely to survive and reproduce. Over time, these advantageous traits become more common in a population, leading to the evolution of new species. Natural section is also an inevitable outcome of an environment in which resources are constrained and for which biological forms compete to sustain and reproduce.

The Inevitability of the Emergence of Biology

Stemming from the inevitability of the formation of stars and planets, and the principle of natural selection, lies the possibility of the inevitability of biology. This process can begin with the emergence of self-replicating molecules, resulting from constant chemical reactions fueled by various energy sources, including the Sun. The potential for biology to emerge through this process is a more elegant and simpler solution to the mystery of the emergence of biological forms than invoking the existence of a designer with an end purpose in mind.

Meaning and Purpose of My Life

If biology — and my existence within it — is merely the consequence of a machinery in motion, evolving through trial and error within the guardrails of natural law, and if, were the wheel of creation spun again, a different outcome would likely emerge — one in which I do not exist — then what does that imply about the meaning and purpose of my life?

Can I find comfort in understanding that my being here is nothing special? Can I find comfort in knowing that I may be an outcome of randomness, and yet, get up in the morning, go and play Pickleball and give my best effort to win, and as the evening descends, feeling content, enjoy a glass of wine? After that, as the hands to the clock inch towards 10 pm, can I go to bed with a sense of fulfilment, looking forward to getting up again the next morning and repeat it over with anticipation and joy?

Even with this knowledge and understanding that my life has no inherent meaning and purpose (or is even part of something that has one), it is still hard to escape its fallout. This knowledge offers no comfort.

The finiteness of my existence and thoughts of what may remain of me (possibly nothing?) after I die can still create a sense of emptiness that is often difficult to accept (in thinking about the consequences of death, it is the end of my personal history that is most disorienting). I often end up grappling with the existential crisis of questioning why I go through the same motions day after day. The force of this question occasionally hits like a hammer without a warning.

Even after knowing that life may not have an inherent meaning, the mind yearns to find one.

Alternatively, embracing the notion that my existence is nothing special can also lead to a sense of liberation — I no longer have to search for something that does not exist. I am free to reimagine the meaning and purpose of my life the way that seems reasonable and convincing.

Recognizing that I am part of a larger, impersonal universe could still allow me to find comfort in the mundane aspects of life. Engaging in everyday activities with focus and mindfulness of being in the present (which allows me to temporarily forget or overcome the knowledge of my inherent meaninglessness), activities such as playing Pickleball, enjoying a glass of wine, or washing dishes (while washing dishes), can provide a sense of fulfillment, albeit effervescent, in a universe that lacks an inherent meaning and purpose.

By acknowledging that although I am fundamentally composed of chemistry and I am an outcome of randomness, I can still be aware of my connection with a larger universe. Further, I can reimagine a sense of meaning and purpose derived from my actions and relationships with others. Engaging in activities with intention and focus, perhaps, I can lead to a fulfilling and content life in a universe that has none.

Perhaps, I can even go beyond that.

Reimagining Meaning and Purpose

In knowing that although my being here has no inherent purpose, I could still live my days and try to leave the universe for the future generations to live theirs (and live it better than I did). And that, perhaps, is reimagining of the meaning and purpose of my life and is the proper tribute I can give to my being here by chance.

Having the luck to live a life (and that too, also being lucky enough to have a good life), its meaning and purpose could be working towards making life of others in the present and in the future have the same opportunity, if not better.

Perhaps, with this notion in mind, a content life is still within my reach if I am to accept the even-present randomness and meaninglessness of everything in the universe while recognizing that although my existence has no inherent purpose, it can still find meaning in my daily actions.

Sitting by the riverbank, contemplating my place in the vastness of space and time, I can find a sense of peace and understanding amidst a universe that has no inherent meaning and purpose.

Perhaps for some of us, this is the path towards a sort of enlightenment and for accepting death and of dying with grace.

I Dink, Therefore I am

In the middle of a Pickleball game
the mind wondered
could I be doing something better
than dinking the pickleball
back and forth
trying to outsmart
the opponents,
and score.

But then I remembered,
I dink, therefore I am.

On the Inevitability of the Emergence of Biology

 

Life is not a miracle, but a natural [inevitable] consequence of the laws of physics and chemistry — Anonymous

Summary: The inevitability of formation of stars, such as our Sun, and planets, including Earth, is rooted in basic principles of physics and the ever-present randomness in the universe. The question of how life originated on Earth, and whether its emergence is also an inevitability, is a question worth pondering over. What follows looks into the factors that may have contributed to the origin of biology and why its emergence is an inevitability.

The Inevitability of the Formation of Stars and Planets

The inevitability of formation of stars and planets can be understood through the basic physical principles and ever-present randomness. The universe is composed of vast amounts of gas and dust, which, under the influence of gravity, coalesce to form stars. Our Sun, for instance, was born from a collapsing cloud of gas and dust approximately 4.6 billion years ago. This process is not unique to our solar system but is a common occurrence throughout the cosmos.

The collapse of the gas cloud into the formation of stars also results in the formation of planets. Small initial motions within the cloud translate into rotation as the cloud contracts due to the conservation of angular momentum. The rotating disk of material that forms around the growing protostar becomes the birthplace of planets.

The Role of Sun in the Formation of Complex Molecules

The primordial Earth was rich in carbon, nitrogen, hydrogen, oxygen, sulfur, and phosphorus — key elements that make up our biology (the biology we are familiar with, although, other kind of biology based on different chemical composition of self-replicating molecules could also exist). These elements provided the raw materials necessary for forming simple molecules, also referred to as monomers.

The presence of a star, like the Sun, in a planetary system is crucial for providing the energy necessary for chemical reactions that could lead to the formation of complex molecules. In the case of our solar system, the Sun’s energy, particularly in the form of ultraviolet (UV) light, played a significant role in driving photochemical reactions that broke molecular bonds and helped form new compounds. Additionally, atmospheric lightning (ultimately also driven by the Sun) provided bursts of energy, leading to the possibility of creating complex organic molecules. The monomers, fed by the Sun’s energy, linked together to form longer molecules called polymers that subsequently became the building blocks of biology.

The possibility of this mechanism was demonstrated in the famous Miller-Urey experiment, where a mixture of gases was exposed to electrical sparks, resulting in the formation of amino acids (monomers), which are essential for biology.

Polymerization and Building Blocks of Biology

Polymerization is the process by which monomers chemically bond to form larger, chain-like, or networked structures called polymers. This process is essential for the formation of complex molecules like proteins that are the basis for biology. Without polymerization, the assembly of complex structures necessary for life would not have been possible.

Autocatalysis and Self-Replication

The basis for the possible inevitability for the emergence of biology is the development of self-replicating molecules. A fundamental property of biology, after all, is some form of self-replication (or reproduction).

At some point in the chemical evolution leading to life, and as an outcome of incessant outcome of trials, certain molecules developed the ability to catalyze their own replication. This phenomenon is known as autocatalysis. In an autocatalytic system, a molecule (A) can interact with other molecules (X and Y) that are present in the environment to produce two copies of itself (2A). This self-replicating capability is a fundamental characteristic of biology.

One example of autocatalysis in prebiotic chemistry is the role of certain RNA molecules, known as ribozymes. Ribozymes (molecule A) can catalyze their own replication by assembling new RNA strands from free nucleotides (adenine [A], uracil [U], guanine [G], and cytosine [C]) (the X and Ys in the ambient environment). The original RNA strand acts as a template, with free-floating nucleotides in the environment aligning along the RNA sequence via complementary base pairing. Once the complementary strand is formed, it separates to become another, but identical, molecule (A becoming 2A).

It appears that moving from the emergence of polymers to self-replicating molecules is a significant leap, involving a highly improbable event. However, the low probability of occurrence is mitigated by the large number of trials of different chemical reactions taking place. The process is also aided by the concept of ergodicity according to which, while a small number of molecules may take an inordinately long time to explore a vast number of combinations, a large number of molecules can achieve the same results over a shorter time span.

Inevitability or Lucky Accident?

The emergence of self-replicating molecules and, by extension, biology itself raises the question: Was it an inevitability or a lucky accident? One can argue that given the right conditions and raw materials, the formation of self-replicating molecules is an inevitable consequence. The presence of key elements, energy sources, and suitable environmental conditions would have created self-replicating molecules allowing biology to emerge.

However, the lack of evidence for biology elsewhere in the universe, so far, suggests that the emergence of self-replicating molecules might have been a rare and fortuitous event. While we have identified exoplanets with conditions like those of early Earth, we have yet to find definitive evidence of life beyond our planet. This scarcity of evidence supports the notion that the origin of life may have involved a series of highly improbable events. However, given the possibility of billions of planets, it might just be a matter of time before we discover nascent or advanced forms of biology.

Summary

The formation of stars and planets, including the Sun and Earth, is rooted in fundamental physical principles and the inherent randomness of the universe. Simultaneously, given the limited amount of energy available on the Earth’s surface, the mechanism of natural selection is an inevitability. The missing link is the inevitable emergence of self-replicating molecules. Once that occurs, the domino effect of inevitabilities can provide a basis for the emergence of biology and eventually, us.

If this were to happen, an explanation for our consciousness, which can reflect on and question its own origin, would not necessitate a reason or an intelligent designer. Instead, one only needs to build upon the inevitable outcomes of a few basic physical laws and simple facts. In the simplicity and elegance of this explanation lies an explanation of our existence. In there lies our connection with the rest that is out there.

Biology: Replication is a fundamental aspect of biology, referring to the process by which organisms create copies of themselves, ensuring the continuity of life.

Drakes Law: Drake’s Law, also known as the Drake Equation, is a probabilistic formula used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way galaxy. It was formulated by Dr. Frank Drake in 1961. The equation considers several factors that contribute to the development of intelligent life, including the rate of star formation, the fraction of stars with planetary systems, the number of planets that could potentially support life, and more

Ergodicity: If you take enough time, you’ll experience everything the system has to offer; A single molecules’ long-term experience is the same as what you’d get by looking at a whole group of molecules at one moment in time.
