A little
food for thought today. Every creature on this planet has its own natural
habitat, a niche it fills. Some are even symbiotic in nature, such as the
clownfish and the sea anemone, or tube worms and their internal bacteria. That
being said, just what is a human's natural habitat? Unclothed, climates can
easily be too hot or too cold. Put us somewhere where there is a lot of direct
sunlight and we will burn and get melanomas, since our eyes and sense of smell
aren't keen enough to hunt or scavenge in the dark. We aren't well suited for
aquatic life. We aren't great climbers. We don't have wings. We don't have
durable claws. So, let's say a moderate climate, slightly humid, near fresh
water, with indirect sunlight at sea level... Anyone have any idea where that
might be? Face it, without our big brain to adapt ourselves and our environment
to our needs, we would be in serious trouble.
So, where do we fit in?
The first movie I got to see when I was transferred to Walnut Grove in 2001 was The Matrix. Still one of my favorite movies. I do not believe that humanity will ever be in a situation like that, but it made me think about the nature of reality and other such things. There is one part I'm reminded of now. Agent Smith (bad guy) is speaking to Morpheus (good guy), whom they are trying to break and find out about the rebels. Agent Smith says,

Agent Smith (bad guy) is speaking to Morpheus (good guy), whom they are trying to break and find out about the rebels. Agent Smith says,
"I'd like to share
a revelation that I've had during my time here. It came to me when I tried to
classify your species and I realized that you're not actually mammals. Every
mammal on this planet instinctively develops a natural equilibrium with the
surrounding environment but you humans do not. You move to an area and you
multiply and multiply until every natural resource is consumed and the only way
you can survive is to spread to another area. There is another organism on this planet that follows the same pattern.
Do you know what it is? A virus. Human beings are a disease, a cancer on this planet. You're a plague and we are
the cure."
That stuck with me. About six years after seeing The Matrix I
was reading an article about viruses that really brought this home.
Something you might not know is that in 2003, when the human genome was fully mapped, it was found that 8% of our genome is composed of broken and disabled retroviruses, called endogenous retroviruses. If it takes less than 2% of our genome to create all the proteins necessary for us to live, to what extent are we -who we are, what we are- affected by the 8% of our genome composed of retroviruses? The rungs of the ladder of human DNA consist of three billion pairs of nucleotides spread across forty-six chromosomes. The sequence of those nucleotides determine how each person differs from another, and from all other living things. Something to think about is how we share, in thousands of exact places throughout our genome, viral fragments with primates like chimpanzees and monkeys.

Endogenous retroviruses aren't newly discovered. In 1968, Robin Weiss found endogenous retroviruses in the embryos of healthy chickens and suggested that they were not only benign but might actually perform a critical function in placental development. He was laughed at. Weiss went so far as to live with a group of Orang Asli tribesmen of the Pahang jungle of Malaysia so he could test the eggs and blood of red jungle fowl, ancestor species of the chicken. They had the same virus.
Did you know that the earliest mammals, up to at least a hundred million years ago, laid eggs? Then embryos essentially became parasites. They began to implant themselves in the lining of the womb, developing a placenta. The placenta is essentially a modified egg, yet allows for the elimination of waste and to take nourishment from the mother's blood while preventing immune cells or bacteria from entering. In the 1970s biologists were surprised to find retroviruses in baboons on a layer of tissue known as the syncytin, which forms the principle barrier between mother and fetus. The same is true in humans. Cell fusion is a fundamental characteristic of mammalian placenta, but also of retroviruses. The protein syncytin, which causes placental cells to fuse, employs the exact mechanism that allows retroviruses to latch on to the cells they infect.
So, where do humans belong? And just how close to the truth is Agent Smith's revelation?
