But that's the reality, thermal stress affects virtually every metabolic pathway because the function of enzymes is temperature dependent. What makes you think that one selection pressure comes along to produce feathers, another comes along to produce wings, a third selection condition comes along to produce flight muscles, and another selection comes along to produce pneumatic bones and so on. What portion of the genome would not have to be transformed to turn a reptile into a bird?

I don't think you understand what thermal stress does to animals, especially if you superimpose starvation, predation, disease... What makes you think that selection pressure in natural are imposed like the selection pressures of the Kishony experiment?

If you are going to claim that fish are related to mammals and reptiles are related to birds, yes, it is useless.

Take a look at Charles Brenner's work and see if you can put the genomes of humans and chimps and see if they are related or determine a MRCA.

But on closer examination, it is found that the pre-proinsulin molecules differ by two amino acids. And is the enzyme which cleaves the pre-proinsulin identical between humans and chimps?

That's right and virtually every gene differs between humans and chimps. And you only have a million generations to make the transformation.

So give us a rational explanation of how this type of transformation can occur.

I guess you are right on this point because there are people who think humans are related to bananas. Of course, that's not based on gross anatomy.

How is a reptile to transform the multiple genetic loci, the proteins, and control modules to make scales into feathers when the fastest evolving replicator known cannot evolve to combination therapy?

And for a mutation rate of e-9, it takes e9 replications for that beneficial mutation to occur. And that's for a single targeted selection pressure. Thermal stress targets virtually every metabolic pathway.

Presumption and speculation. So how do you think rmns works? Do you have a mathematical explanation that is verifable by repeatable experiment?

What's the probability of the right mutations coming along?

That's why it must be peer reviewed before it is published. Errors can still occur. If you think there is an error in my math, where is it. If you think there is an error in the physics, where is the empirical example that works differently from this math?

I doubt he was using my math. There are many references which put the mutation rate for e coli at about e-9. I suspect that Kishony has a pretty good idea of the population sizes for his colonies. He certainly didn't say thousands or trillions for his colony sizes. One of the basic things that microbiologist do is colony counts.

"Junk DNA" gets ignored because it doesn't fit the presumptions.

Oh really? So why are there so many different estimates for the similarity of human and chimp DNA?
