My fingers are tired from typing! lol. This is my last post of the night.
You are not discerning between macro and micro evolution. Micro-evolution is the adaptations and changes within a species while macro-evolution is the addition of new traits or a transition to a new species. Micro-evolution is a fact that is plainly observable throughout nature. Macro-evolution is a theory that has never been observed in science. Evolutionist usually argue that those who believe in creation are ignoring the facts, however, there is nothing that evolutionist observe in science that creationist or Christians as a whole disagree with. Evolution is a hypothesis introduced as a possible explanation of origins.
A fact of genetics is that trait changes have a ceiling. This perhaps is the biggest obstacle to gradual change through micro-evolution. Each rung of DNA is made up of four chemicals called nucleotides, designated by the symbols: A (adenine), G (guanine), C (cytosine), and T (thymine). These rungs of DNA are combined to provide a blueprint of the traits that organism will have. If you took all the DNA in the human body and put it in written format, it would fill up one million volumes the size of a 500 page encyclopedia. With all this genetic data, if two people could have as many children as there are atoms in the universe, no two children would be identical. Though there are a limitless combinations of traits that we possess, there is a limit to how far each trait can change. There is a limit to the number of combinations of these chemicals; therefore there are a limited number of trait variations. No new genetic material can be added. Trait changes result in re-arranging the genetic code that is already present. Mixing the available genetic code will produce variations in the trait but will not change into a completely different feature. For example, your parents genes are combined to produce your various traits. People have several different colors of hair, eyes, and skin, but without a mutation, these traits will remain within its boundaries. There are mutations that can occur and mutations almost always cause diseases or defects. However, even under mutation, skin will still be skin and eyes will still be eyes. Because of the code barrier, there are a limited number of variations in eye color. Different genes can create distinct variations but there is a limit. There can be rapid changes but inevitably, there is a return to the norm.
I'm going to leave it there for now. This is actually straying very far off topic now and it isn't far on the original poster.
