I think denying evolution helps neither Christians nor conservatives. It’s been proven that change in species (including humans) happens; but that fact in no way negates belief in God, Jesus, limited government, The Second Amendment, the Constitution, etc. See Pope John Paul II, a devout Christian and enemy of communism who acknowledged evolution.
I agree with your post. The proven change in species is referred to as natural adaptation [sometimes called micro-evolution]. What is often over-looked [besides the sheer complexities of DNA/rNA] is that most likely these micro-changes had to be pre-programmed into the DNA too. In other words each life form has certain traits and characteristics that can be turned off and back on as changing conditions require.
These are fairly important concepts because not only do they indicate an intelligent designer they also indicate a designer who could anticipate these changing needs ahead of time or rather outside of time itself. Almost as if just maybe this Designer, or God if you will, - gasp - created not only these complex inter-dependent life forms but the physical natures of space and time too - ex nihilo or out of nothing! Praise God from whom all blessings flow!
