It is partly code, but that's not all it does, it's also the switches and how it works is based on shape and location, not just the "code".You just describe it that way. When you say DNA isn't code, when it looks and acts like code, makes it something... else... that does unbelievable things.
A mechanical switch is either on or off. A DNA switch is not just on or off and it may interact with other proteins that may modulate the action of the switch protein, depending on the situation.We model DNA as code. What does "modeling the chemical basis" mean? Let's say we find a switch in DNA. It won't matter if the switch is chemical or electrical or mechanical, it's modeled the same way. To say otherwise is to claim that some switches are magic.
What really makes the difference is how often a protein interacts with DNA, these are molecules that jump around. If it's attached to DNA 60% of the time, maybe that's one level of on, then 40%, 20% etc. Then maybe it interacts with two other proteins 10 and 5% of the time. But for every DNA switch you'd have to find ALL of that out before you could even model a single cell and *then* try to model mutation and selection with multiple iterations of said cell.
Which is why I said it would be easier to model the chemical basis of proteins and DNA, then you wouldn't have to know everything beforehand because the model would act the way a real cell does automatically.
Anything you use to model evolution is going to have to have some kind of selection criteria. I'm guessing you will complain this is a "goal" no matter what.Example? Can we extrapolate that model to some kind of simple model of common descent that doesn't include a goal?
Yes, he's only looking at microevolutionary change. The evidence for common descent is already well supported by fossils and DNA.Lenski hasn't found anything that helps to show common descent. What he has found is two things. The first, and the majority of the cases of improvement in fitness, come from something breaking in the DNA. And since we can de-code what breaks, we know DNA in bacteria is code. A minority of cases is an improvement from existing code that is accessed by few mutations.
Scientists compare organisms and see that larger changes are made by small adjustments in developmental genes. This is already known so I don't know why you think it is some kind of "failure".Evo devo will not save you. The reason Evo Devo exists is because it became apparent that mutations could not build the complex code required for life. They had to think of a way to get big changes from few mutations. But Evo Devo is just a subset of mutation plus natural selection and has to live with the same consequences.
I didn't see any predictions made.You didn't read. It makes very powerful predictions about relationships between groups. It's much more accurate about relatedness and shows common descent hierarchies are wrong.
Not at all. He goes through individual stages, each of which have a selective advantage. A cup shaped eye patch, a more and more constricted eyepatch, then the evolution of a transparent layer.When you say things like this a layman like me can only point at the emperor and declare he has no cloths. Dawkin's model is this:
1. Light sensitive patch exists
2. Magic happens
3. Eyes!
Why then do mitochondria and chloroplasts have circular DNA like bacteria? Ribosomes that are most similar to bacteria?The changes required for bacteria-like organisms to become parts of cells takes a lot of mutations. Good luck with that.
How many? Is that really the question when plenty of organisms are able to keep chloroplasts alive for extended periods within their tissues?Again, though, endosymbiosis is a theory based mostly on looks. If it wasn't based on looks, common descentists would at least want to know a rough answer to the question of how many mutations it would take to pull off a trick like that. But they *don't even ask the question*.
Hydroplates are a cartoon version of the flood.The evidence for the flood is huge. A couple examples are the Grand Canyon and the vast sediment layers. And they are just a couple in a mountain of evidence for a catastrophic flood.
However, my point is that you seem to look at the flood in a cartoon way despite people showing you how the cartoon version you keep talking about is wrong.
I guess you're not interested in that book I mentioned?
