I’m new here but wanted to share my thoughts as I was wondering about theistic evolution versus ID as well since I’ve been in ongoing discussions about evolution with a good friend who left the faith because he couldn’t reconcile evolution with God.
I’m not a scientist, just a simple mind trying to think critical about his own believes.
So here’s what I came up with:
A) Old earth / old universe
Sure this proven by now (based on speed of light, moleculair clock, etc.).
B) Common descent human from a proto-chimp
Sure this is (statistically) proven by now, retroviruses (ERVs) in humans and chimps are for about 99,8% in the same location.
C) Random mutations lead to rise of new organs or new bodyplans
Not really possible because of:
- Combinatorial inflation (making a random search for functional sequences a needle-in-a-haystack proposition)
- Mutational load in the genome
- Explosions of plant- and animal life in the fossil record
D) Natural selection or neutral selection or something else
This fully hinges on C (random mutations). You can’t select something that doesn’t exist?
So this leads me to conclude that God took a proto-chimp and build the first human out of it (common descent). Seems logical (God built Eve out of Adam too) and I think I would do the same (starting all over again is quite inefficient?).
One of my conclusions is that it’s important to make a distinction between common descent and improvements in body plans based on random mutations.
Common descent makes scientifically sense while random mutations leading to new biological structures is hard to prove.
So I guess I believe in common descent but the process cannot be random so ID seems most reasonable to me.
Please let me know if my reasoning is evident or if it makes no sense at all
