Finding our way through it all
With such low entropy in the very beginning of the universe, we're on our way to higher entropy. And that's just the way it is -->
Symmetry plays an interesting role in life. I believe under this same belief, when the universe started, it was for the most part, controlled (chaos is a beautiful thing). Massive amounts of energy expanded at an extreme point of low entropy, and since that one occurrence (big bang), we've been in a chaotic system, as the universe continually expands away from the initial point of existence within the framework of gravity.
Within that moment is time. A fourth dimension of space. Within space-time is symmetry. Why? Because as time goes on, energy expands. Energy however, doesn't pick and choose where it goes. It symmetrically expands out. From there, certain aspects of organized-chaos continue that symmetry. Planets formed and cooled, allowing not only gases to find a home, but eventually living organisms that were able to successfully grow and thrive.
And just as energy is still expanding symmetrically, we grow the same way. Embryonically speaking, each phase is perfect (depending how you look at it).
Competition is bred within us today on more of a societal level shown on the outside, and sometimes difficult to think of it coming from the inside (DNA). Competition, atmospheric conditions, the sun, and elements (from our periodic table) from the Big Bang and the cosmos, allowed for organisms to evolve.
Organisms on Earth didn't have a choice in the beginning with the painfully slow processes of evolution. Perhaps, they were floating along minding their own business, through a chemical reaction that just so happens to be perfectly symmetrical (or else the components and product aren't stabilized or the reaction/solution would break down), started to take in oxygen. This didn't have anything to do with the organism however, so much their environment inhibiting them to take on the reaction.
When Earth was formed, the rock didn't have much chance to harness life. It was just figuring itself out. Being battered by meteors, massive volcanic eruptions, ice-age, and the continental drift does not sound like appeasing daily activities for Earth. For humans, there's an MVP out there. And, lucky for us, after 2.3 billion years we still live with them! The, all-mighty, unicellular, no membrane around anything, but can do almost anything you want it to, cyanobacteria! These guys from colonies called stromatolites, and can fix anaerobic conditions, atmospheric Nitrogen, and pump out some f'ing Oxygen. It's insane. This helped lead the charge for biodiversity (after a very very long time), which helped to ramp up the processes of organisms that were finding new ways to grow, stretch, move laterally, see, feel, swim, walk, and fly.
Today, cyanobacteria can still be found, and are known to be called the most diverse organisms on the planet. They do many wonderful things for us and plants.
Within genes every once in a while, a whoopsie happens. That woopsie may die off. But also may live on. That woopsie may breed into another woopsie. Now, a pattern begins to take shape, and the chain of events continues for more and more woopsies turning into perfection (depending on how you look at it). This is a simple probability event that occurs within DNA. What a crazy little guy this is.
The components of DNA consist of phosphates, sugar, and Nitrogen.
Phosphates are found within the structure of Earth, as we're still mining phosphates across the world. Sugars, which are composed of five Carbon atoms, help to form the sugar-phosphate backbone of DNA. Nitrogen comes along with Oxygen and Hydrogen to help bind DNA together.
So how about that? We were built from the same material we're standing on today. Phosphate is found within 85% of our bones and teeth. Sugars come from Oxygen, Carbon, and Hydrogen (mostly water), and Nitrogen is almost 80% of our Earth's atmosphere!
The scary part is realizing what else has been living a lot longer than we have, on the same planet. What's with them? How were they able to survive for so long? What don't we know yet about ourselves? We're a very fortunate species. Fortunate is highlighted here. There's a lot more out there we need to learn. A lot more we need to learn about ourselves. We haven't been here that long.
