Stages of Evolution
Stages of Evolution – What are the Seven Fundamental Stages?
There are seven stages of evolution. Each one is a basic fundamental stage essential to the scientific theory of evolution.
The first is "Cosmic Evolution" - the idea that space, time, matter, energy, natural law, and information "exploded" (or expanded) from essentially nothing in the sudden "big bang" (a singularity) that was the birth of our universe.
The second stage of evolution theory is "Stellar Evolution." The big bang is thought to have produced only Hydrogen, Helium and a variety of subatomic particles. Subsequently, Hydrogen and Helium condensed into stars.
The third stage is "Chemical Evolution." According to big bang cosmogony, the only chemical elements produced by the Big Bang were Hydrogen and Helium (and possibly Lithium). Due to the incredible heat and pressure within stars, Hydrogen and Helium evolved into the remaining 88 naturally occurring chemical elements we observe today.
The fourth stage is "Planetary Evolution." The higher chemical elements thought to have evolved within ancient stars were somehow ejected, possibly at the conclusion of the stellar life cycles, releasing great clouds of swirling chemical elements. These swirling clouds of chemical elements formed solar systems including our own.
The fifth phase is "Organic Evolution" - spontaneous generation. The theory is that the planet Earth began as a molten mass of matter. It cooled off into solid, dry rock. It rained on the rocks for millions of years forming great oceans. Eventually, this "prebiotic rock soup" (water + rock) came alive and begot the first self-replicating organic systems.
The sixth phase is "Macro Evolution." All living creatures are thought to share a common ancestor: a relatively "simple" single-celled organism, which evolved from inorganic matter (rock soup). Essentially, the birds and the bananas, the fishes and the flowers, are all genetically related.
- The seventh and final stage of the theory is "Micro Evolution." Micro Evolution is the variation and variety of traits expressed in sexually compatible "kinds" of organisms. Examples include the superficial differences between sexually compatible kinds such as llamas and camels, lions and tigers, coyotes and dingoes, etc.
Stages of Evolution – Nature, Time, and Change
There might be other ways to divide the stages of evolution, but it really comes down to the scientific theory of “Change” in “Nature” over time. General Evolution is a continuing effort in science, which attempts to explain how Nature changed the universe from the chaotic Big Bang into the complexity of stars, galaxies, solar systems, and our earth.
Biological Evolution is a continuing effort in science, which attempts to explain how Nature changed inorganic materials into the first organic molecule, and how Nature gradually changed this first organic molecule into all complex life forms on earth. Simply, Biological Evolution is the theory that all organisms descended with modification from a common ancestor (the first little guy was changed into everything else).
Why refer to ‘Nature’ with a capital ‘N’? It seems the study of scientific “change” is limited to evidence in the natural world. Therefore, Nature-driven Evolution is the only “History of Life” theory currently available for our consideration. Contradictory explanations are not considered legitimate scholarship. Therefore, being flippant while making a point, we decided to give Nature the proper respect it/he/she deserves.
How did Nature create itself/himself/herself? How did Nature change the nothingness to everything? How did Nature change the first two chemicals into the entire periodic table? How did Nature spontaneously generate the first biological molecule from inorganic materials? How did Nature change the first biological molecule into a self-replicating cell? How did Nature increase complexity by adding millions and millions of chemical letters of biological information in a specified sequence to operate biological machinery and reproduce complex life forms? How did Nature supply the first so-called “simple” organisms with the genetic code needed to make and pass along changes in the first place?
