Origin of Life

Very little is really known about the origins of man because – as is the case with so many branches of science – new discoveries are constantly displacing old theories. Mankind is still largely viewed in Darwinian terms, except by those who subscribe to the beliefs of Christianity and the explanation of creation offered in the Book of Genesis. This biblical account at least grants us the dignity of a soul and a loving creator – or at least, a creator who cared enough to bother to give us life. But many people have grown dissatisfied with both of these stories about mankind’s origins, feeling that they do our race a disservice. Of course, there are also those that believe that Earth may have been “seeded” via another planetary body or even aliens. This concept of panspermia may seem outlandish but then, so is the fact that life seemingly “appeared” on Earth a few billion years ago. There’s no real evidence to support this theory but then, it’s not entirely beyond the realm of possibility either.

For as long as we’ve been self-aware and able to reflect upon our own existence, we’ve created myths and theories to account for how we got here. More often than not, when we ask, “Where did we come from, and why are we here?” what we’re really wondering is, “Of what inherent value – if any – is my life?”

If the answer you cling to is that your life is the random result of accidental chemical reactions followed by a survival of the fittest evolutionary process, then your ideas about the value of human life are bound to be pessimistic. The prevailing scientific view holds no room for any sacred purpose behind our existence. If, on the other hand, you believe that you’re the creation of a jealous God who later decided that He liked one group of people best and would help them to smite all others, then your view of humanity may not be any more uplifting. Both ideas have created a lot of unrest and general unhappiness in our world, because if we think that our own human nature is either a happy accident or a sinful creation, then how highly will we regard the lives of others?

Few of us escape the social conditioning – the indoctrination – that offers us two fundamental definitions of our nature and the nature of the universe. We can accept that we were created by sheer chance, and that millions of years of unfeeling, tooth-and-claw natural selection resulted in the formation of our consciousness, our very capacity to think and feel. Or, we can accept that we were created with divine intention, but with inherently sinful natures; and we’re surrounded by a tainted world that keeps tempting us to fall farther away from grace. Neither philosophy encourages us to view the life of self and other as sacred. Creationism or Darwinism: How about doing away with both?

It would be beneficial for us to either create new stories that honor the nobility and mystery of the human spirit or else admit that we just don’t know anything for certain about our origins. Our children, naturally inquisitive and creative as they are, can speculate for themselves and perhaps come up with more life-affirming explanations than the ones currently being offered to them. At least this way we’d be preserving some of the mystery and wonder of life for them.

Part of the reason why fierce debates rage around the origins of man – in the conflicts between Creationism and Darwinism that we see within many schools, for example – is because our beliefs about where we came from can strongly influence our sense of identity and our feelings of self-worth. It’s impossible to separate our self-image from our life philosophies in that regard. The stories we cling to will paint our inner pictures of who we are, where we come from and what our race can achieve.

Unfortunately, the stories that we’ve inherited in our culture paint a fairly unflattering picture that does little to inspire us to discover and express our true potential in this world.

Science spins its own version of reality. If you believe that the sky is blue because of the chemical composition of the gases that exist up there, and the way that light refracts off of them, then that’s all you’ll ever see. You won’t perceive the unfathomable mystery of it all. What is the true nature of light, or gases, or the color blue? Questions like these are beyond our ken. The theory of evolution teaches us that it’s useless to ask such questions anyhow, though. This theory, which forms the backbone of so much scientific thought and of our very definitions of humanity, maintains that matter came first and consciousness emerged later – almost as an afterthought; and certainly by accident.

consciousness (1)What if the mind formed matter? What if consciousness preceded everything else, and created form? Our scientific indoctrination has convinced us that reality works the other way around, but we’ve been offered little actual proof of this. What is obvious, however, is that the belief that consciousness always comes first would do much more to uphold the beauty, grace and potential of our natures than does the belief that our existence was the random result of accidental evolution.

We would do well to adopt stories that inspire us and offer us a new vision of what humanity can aspire to. When trying to grasp the nature of our reality as human beings, and drawing upon the resources that civilization offers us, we’ve thus far been essentially left with a choice between atonement (the predominant religious thinking of the West), accepting that the world we exist in is illusory (the predominant religious thinking of the East), or the theory of evolution. Typically, we are never taught or encouraged to believe that we are, ourselves, divine.

None of the arguments that uphold a notion of a barren and sterile universe can hold water. Most children know better than to believe in those wet-blanket descriptions of reality. Sadly, though, they eventually learn to accept them. How could they not, when our cultural beliefs make their survival virtually dependent upon it?

Love has to come from somewhere. But within the world’s established religions, love always has its conditions; and within the world of science, love can be explained away in terms of neurological transmissions and chemical interactions. It seems that our race, by and large, is willing to accept practically any belief except for one that maintains that what we are is something miraculous.

Most scientists or religious scholars would dispute that we are miraculous, by virtue of being conscious beings. Could it be that consciousness came first; that we did not become humans by accident? What if consciousness created our world in order to express all that it is, and to become better acquainted with itself? If this is true, how might it change the idea that consciousness will arise in machines once we’ve reverse-engineered the brain?

As demonstrated in Jessica L. Tracey’s paper, Death and Science: The Existential Underpinnings of Belief in Intelligent Design and Discomfort with Evolution (referenced below), many turn to intelligent design theory in search for meaning when faced with their own mortality. Despite the scientific proof supporting evolutionary theory (and the one that I believe is most accurate), intelligent design is perhaps a worthwhile theory because it provides people with what they seek, which is purpose and meaning.

The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public. The notion that we are the only example of a successful life form in the galaxy has, for many, seemed like an unlikely statistic, as we discover more and more habitable planetary bodies and hear yet more evidence of life’s ability to survive in extreme conditions.

Tracing the tree of life back to a single ancestral form
A study published in PLoS Computational Biology maps the development of life-sustaining chemistry to the history of early life. Researchers Rogier Braakman and Eric Smith of the Santa Fe Institute traced the six methods of carbon fixation seen in modern life back to a single ancestral form.

Could cloning and genetic engineering improve our chances of successful space colonization in the future? For example, what if we identified an exoplanet that is capable of sustaining life and sent frozen embryos on a 10,000 year journey to the planet where they would hatch(?) upon reaching the destination planet? Or perhaps genetic engineering will be required so that humans can evolve to survive life in space or on exoplanets (i.e. longevity, adaptability, etc.). Is this something that is worthy of further examination? Let’s briefly examine the process of cloning today and then decide. Read More →
