This isn’t supposed to be a YEC argument against evolution (I lean towards Evolutionary Creationism), I’m genuinely curious. Is there something inherent to DNA that causes symmetry? Or is it a consequence of cellular structure? I’d be interested in knowing the answer.
I possibly should clarify that by "duplicate it" I don't mean in DNA. I mean there are other genes that mean code for e.g. a leg just gets used/expressed twice. So more symmetry literally requires less DNA*.* To be honest I never read or heard this anywhere (that I can remember) I just assume it to be the case because it makes sense. I'll let lancia correct me if I am completely making it up .
