@farmerman,
Quote:Evolution makes us consider the total bag of random genotypes possible in each generation. The aspects of natural selection of these random genotypes is fairly well understood for each evolutionary step. (ya cant have wings usable for flight, until ya have feathers and then raches and asymmetric feathers).
I do not disagree with natural selection. I can run a model of natural selection today using an auto factory as a model. This model seems like a logical one to use for a real time test to compare different versions of biological evolution. The auto factory is very similar to biological evolution in many ways. Both models use living organisms to guarantee that the system will run or exist for generations, so that complexity can be added in a step by step way, over a long period of time, from simplicity to complexity.
Both exist in an environment or marketplace where natural selection can be tested as a guiding force in which direction the evolution will go.
Both have ways to record the additional information as it evolves and adds complexity to future generations in DNA or blueprints.
In both the evolution of say the eye of an eagle, and the evolution of the backup camera on a car, there are multiple parts added to each system. In both models, systems completely different purposes are combined for the final more complex systems to work. All the parts don't have to be added at once and some parts are already there and just need to be modified. There was already a wiring harness running to the back of the car that could be modified to carry the signal from a digital backup camera, to the front where the driver can see it in a digital monitor. And, there are some nice chrome pieces to mount a camera to, and the car has a computer chip in the radio that can be programmed to accept the information from the camera and put it on the radio screen. Likewise, an animal does have a nervous system and a body. Likewise an animal does have a body to support the different living cells of the eye, it has a nervous system that can be modified to carry the new picture sensed by the eye, it does have some sort of brain that can be programmed to receive the signals from the eye and turn them into something the can use to determine color depth perception, and all other comparisons so something like an eagle can tell the difference between a floating log and a fish, and then catch it and snatch it out of the water. The technology for the camera was added over time to blueprints in camera factories, till a digital camera small enough was designed to fit in on the car and provide a clear digital picture to a digital monitor in the stereo. I think it is logical to assume that information can be store similarly in DNA.
The only difference between the factory model and the biological model is how the new information is stored for later use and then pulled out of archive for use when needed for the jump in evolution. The factory uses decisions by intelligent managers in multiple factories. The biological model uses random mutations of DNA to provide new genetic information to be selected naturally by attrition or death
Quote:Gungasnake tries to argue (waay unsuccessfully might I add), that these features must occur simultaneously. You dont think that way do you?
The fossil record and model changes of cars, shows big new functioning devices being added over very short periods of time (gaps in the fossil record). I don't think it is necessary or possible for all the steps in the evolution of the eye or the camera to happen in either the factory or biological model to happen simultaneously. But there are some things that must happen in both models.
1. There must be storage of unnecessary information so it can be used later when it is necessary.
2. Both need an explanation of why all unused information wasn't stored.
3. Both models need an explanation of how unused information was stored but not used.
4. Both models require an explanation of how the new information for the addition of the camera or eye, was created.
5. Both need an explanation of how all this stored information was later selected, arranged used correctly, and suddenly added over a short period of time, to match the fossil record. Because in both models incomplete nonworking additions do not survive.
I think you have provided sufficient scientific evidence to answers how biological evolution has fulfilled the first three requirements but, in my mind, only the factory model provides a logical solution to the last two requirements which is,"somebody intelligent created and managed the new information".
If random mutations are sufficient to create the information, store it, and manage the storage and retrieval for later use, then the factory model should be able to be adjusted to mirror it. That would, in my mind, make natural selection of random mutations as the driver behind biological macroevoultion a logical theory for me.
That could be done by removing all human creative intelligence when making changes to the blueprints and any computer programs that mange any system in the factory or in the car. (I would like to discuss adding some constraints to how the random changes are added to the DNA here, to match a type of grammar or system that is required for DNA operate. But, that seems to be cheating because, we are now reintroducing intelligence into the system.)
A working model should then be able to be observed evolving in real time, or simulated in a way that life spans of real time can be sped up. This model would then show random changes to the blueprints with no management of the information they provide, is all that is necessary to add the complexity to the DNA we are modeling to match what we observe as macroevolution in the fossil record. That would, in my mind, make natural selection of random mutations as the driver behind biological macroevoultion a logical theory for me.
