Mutation and selection

Now you did a good job searching the internet for some science on the subject, But this science says zero about how this process evolved. That is my question. Do you have an answer?
I do. By mutation and selection, natural processes known to exist, unlike this Jesus character you mention in the O.P.
More specifically, and for part of the story, the duplication of a gene and its subsequent mutation seem to have added a key component to erythrocyte spectrin, which is a key to the functioning of mammalian red blood cells in the absence of new protein synthesis.
As you're interested in the subject, you'll enjoy this:
Some analysis of one aspect of mammalian RBC evolution
Apart from that, your objections in the O.P. would be met by the fact that the ancestral reptiles already had the features of RBC production and circulatory organs necessary to cope with the changes in the mammalian system.

Explanations often come when we expect them the less
Olivor, I'll happily discuss fused chromosomes and pig genomes if you want to start threads on them, but here, we'll be told that we're off topic, quite rightly, because neither of them are mammalian red blood cells, are they?
So, why not start a topic on whatever you're interested in?

maybe their forum needs visitors from this forum to stir things up?
Well spotted. I figured out who Alpha probably was when he first started posting a lot here. Percy might have guessed as well, as he has posted on "fairytale".
I assure you, their forum does have visitors from this site (sometimes in disguise) who (gently) stir things up.
