Why Evolution makes sense to me.
What if Man is simply the by-product of Nature’s great experiment? Imagine for a moment that every living creature on the planet came into being in a very specific order. I’m not talking about Intelligent Design, here, but rather trial-and-error.
We know for a fact that bacteria, for example, are very adaptable; they can adjust themselves based on their environment. One might wonder then if, given enough time, these bacteria might not combine to create larger, and more complex, life forms. And over the course of billions of years, these bacteria have manged to thrive in land, sea, and air.
So taking this into account, we look out upon the world and wonder at all of the animal life. Every species has a chartable, and thus predictable, list of habits associated specifically with that species. Once you study, and understand, how one crocodile acts, or responds to stimulus, you can know exactly how to deal with future crocodiles. The same works for birds, wolves, etc.
But then we have Man. What I find interesting is that many cultures through-out history have associated Man with multiple animal groups. One does not confuse a wolf with a leopard, yet Man can be associated with many different animals. The American Indians would quest to discover their Spirit Animal, the creature which best defined their personality, for instance.
Even today, we have a tendancy to associate people with various animals based on how those people conduct themselves. Someone might be called a weasel, or a work-horse. The question arises, then, if Man is not simply Nature’s next physical experiment. If one were to take a long, hard look at all of Man’s accomplishments, one would find that Man- unlike most animals- has managed to thrive on land, in sea, and in air. Hell, we’ve even gone to space. While we can’t breate in the ocean or in space, nor do we have wings with which to fly, we have been gifted with the ability to adapt to these environments due to our physical make-up (Giraffess can’t weild hammers, for example).
I believe our animal personalities are simply the remnants of code passed down through our genetic structure over the years as our physical forms have adapted and changed. The end result being that our physical form has finally leveled out (two arms, two legs, etc.), while our personalities remain in flux to provide stability within the species. Yet the genetic code has still managed to continue pairing specific personality traits with specific physical traits.
For example, muscular people tend to have more assertive personalities. Have you ever seen a man that reminded you of an ape: large muscles, swinging gate, etc? What kind of personality did that man have? In my opinion, the same stereotypes can be applied to most human beings.
Just for fun, take a look at this website: http://www.animalinyou.com/index.php
You’ll notice a link on the left titled “Take the Test!”. When you answer the nine-question, multiple choice test, try to answer based on how you’ve noticed others perceiving you, or treating you. Are you small or large in their eyes? Motivated, or lazy? I think you’ll be surprised at the answer you get on the test, and its description of you.
And for the record, I’m either a Bat, or a Snake, according to the website.
