The Social Amoeba

So how is a human being like an amoeba? Amoebae represent what we think of a single celled life form. While amoebae may seem simplistic, they are for more complex than appearances suggest. For one, they possess one hundred times more base pairs in their genome. Even so, amoebae seem to live for one one purpose, to eat. The pseudopod reaches out, embraces a hapless microorganism, constricts, kills the cell, absorbs its nutrients, and excretes what is left.

Humans, too, absorb and assimilate and consume whatever crosses their path. What is not wanted or needed is discarded by the wayside. Consumer society is replete with those who purchase, use up, and toss aside.

Yet, the likeness does not end there. Amoebae respond quite dramatically to osmotic pressure. In salt water, the amoeba becomes isotonic, shrinking as water is excreted from the cell. On the other hand, is fresh water the amoeba becomes hypotonic, swelling in size and in some cases bursting.

In social circles, human beings respond similarly. When we enter into an environment we consider weak, we swell with pride. As an expert, what we know of the topic of discussion provides an advantage. This allows one to speak freely and with confidence. One must be guarded, however. Just like an amoeba, we may overdo it, metaphorically bursting with bravado.

Likewise, when we are at a disadvantage, when everyone around us is the more knowledgeable, we shrink into ourselves. We become small, quiet, unassuming. At the very worst, we may even retreat to some isolated space. Like the amoeba, we form a protective shell and wait for the danger to pass.

However, there are those of us that, like marine amoebae, have no social equivalent of contractile vacuoles. That is to say there are those who seem unaffected by the social environment in which they happen to be dropped. When either at an advantage or disadvantage, certain people neither swell up or shrink away. They remain fixed, unchangeable. This unique adaptability serves one well in matters of discourse, neither seeming timid or prideful.
