Well, one of these is the microbe that’s normally found in the environment. Would you believe they’re also found in us? They don’t just crawl in and around your body and find requirement to live.
If we can only look deeper inside our body, we will see not only human cells but even cells of microbes.
In an article of the National geographic Magazine, if you’re going to count the living cells in your body, you’ll find about ten times more will be microbes? Unbelievable huh!
In addition, the dense population of these microbes is in your intestines. You might not feel them. But if you’ll be like their size, I’m sure you’ll be shocked to know that you’re a parent with trillions of offspring to feed.
However, to know at least their classification, scientists have grown snippets of DNA in laboratories. They’re able to conclude that each of us carries 8000 subspecies of microbes which belong to between 500 to 1000 species.
These scientific findings enable us to answer the realities on human beings. But these still confuse me a little. If most of our cells are not even human and we have ten times more microbial cells than our own body cells; then why are we defined to be human?
Or should I say that’s what the word ‘human being’ denotes, to build up with mostly nonhuman cells. Imagine how ironic that is!
Our body is not only a simple home to these microbes. We’re not just providing their environment, shelter and other needs. It’s not just a place of survival for these multitudes but primarily a place for interaction and partnership.
I remember when my biology, anatomy teachers taught us that an ecosystem must not be called ecosystem if there’s no interaction between organisms and their environment. So what do you think of yourself?
These microbes are not destroyers. They’ve already been part of the human evolution because we, together with our ancestors, couldn’t survive without them.
Everyone knows that we behave as hosts of these microbes because where else would they get their needs? We in return take great advantages from them. Most of these microbes regulate some of our body functions. One example is the gut microbes, they carry out vital role in digestion.
Also, some of them cause production of vitamins essential for good health. Besides, some help us avoid diseases. From all of these, the human body is really a composite community of crawling microbes. That is because they build us up into a complete ecosystem where we can fully benefit from all that we have.
So it’s about time, we should know the length of the human’s foot. We’re nearly a biosphere, a land dominated by a vast n umber of creatures not even related to us humans.
