Networks, Bacteria, and the Illusion of Control

Another great post from Brainsturbator worth reading in full. Some excerpts:

 

....Most of the cells in your body are not your own, nor are they even human. They are bacterial. From the invisible strands of fungi waiting to sprout between our toes, to the kilogram of bacterial matter in our guts, we are best viewed as walking “superorganisms,” highly complex conglomerations of human cells, bacteria, fungi and viruses....

 

....One study concluded that children who grew up on farms had fewer allergies than their counterparts in urban areas. Conversely, health studies have shown that mothers who kept their children in antiseptic environments were actually compromising their health. Children need to be exposed to the natural environment of threats and benefactors so their immune systems learn to distinguish between the two.

...scientists have determined that 90 percent of the cells in the human body are bacterial. Only five percent of the cells in your body constitute “you,” in the sense of your genetic heritage. In relative scale, bacteria are much smaller than your own cells, so they account for only a small fraction of your body weight. Nearly all of these microbes are located in your gut, where they keep you working at optimal health....

 “We would have to accept that bacteria, touted to be our enemies, are not merely neutral or friendly but that they are us. They are direct ancestors of our most sensitive body parts. Our culture’s terminology about bacteria is that of warfare: they are germs to be destroyed and forever vanquished, bacterial enemies make toxins that poison us. We load our soaps with antibacterials that kill on contact, stomach ulcers are now agreed to be caused by bacterial infection. Even if some admit the existence of “good” bacteria in soil or probiotic food like yogurt few of us tolerate the dangerous notion that human sperm tails and sensitive cells of nasal passages lined with waving cilia, are former bacteria. If this dangerous idea becomes widespread it follows that we humans must agree that even before our evolution as animals we have hated and tried to kill our own ancestors. Again, we have seen the enemy, indeed, and, as usual, it is us. Social interactions of sensitive bacteria, then, not God, made us who were are today.”
