VML, I'll admit I haven't looked at evolution in years. But, as I recall since nobody was there as evolution took place and they've not yet discovered a means to measure the effects of environmental changes that occurred eons ago, that "environmental changes" is a theory. Do you have a link to it actually being more than a theory? If you do not, respectfully, couldn't the mechanical process of predestination be as likely as the mechanical process of environmental change? Of course, I realize that by asking the question there has to be an assumption of God in a predestination mechanical theory. Nnanji, you seem to be asking for a dissertation on geology and paleontology, which is a pretty exhausting endevour. How about this, I will give you some of the information I have stored away in my hippocampus and we can build from there. This is going to be somewhat scattershot and disorganized but I will give it a go. Probably most importantly is the use of natural radiation to determine the age of rocks and fossils. We have calculated the rate at which uranium crumbles and gives off slightly smaller particles. Uranium-92 decays to become Thorium-90 If we measure the amount of Uranium in a rock and compare it to the amount of Thorium we can apply our knowledge of the rate of decay and estimate how old the rock is. This is applicable for very old rocks and as I recall is the basis for estimating the age of the Earth. The radioactive carbon isotope C-14 decays to become Nitrogen-14 with a half life of 5730 years. Half-life means that half the amount of carbon will have become nitrogen in 5730 years. Another half of C-14 will change in the next 5730 years, and so on. Always disappearing by half. This is very convenient because "organic" molecules (the basis of all living things) contain carbon isotopes. We can compare the quantity of C-14 to the quantity of N-14 in a fossil and derive its age. Uranium has a very, very long half life and is not suitable as a measurement for fossils and newer sedimentary rocks, such as make up the strata of the walls of the Grand Canyon. So, we can collect down the side wall of the Grand Canyon and calculate the age of the rocks by measuring the quantities of carbon and nitrogen isotopes in the fossils. I hope that is helpful for a start. Thanks VML. I have a graduate degree "in science". My favorite chemistry professor had a pet rock. The Rock was uranium. He'd bring it in while he was teaching organic chemistry and make a cloud chamber by putting a little rubbing alcohol in a chamber and then evacuating atmospheric pressure until the alcohol cooked off and made a cloud. With the cloud you could actually watch the trails as particles emitted from the radioactive decay. If for some reason you didn't want to participate that day in organic chemistry, he always had that alternative entertainment. Thanks for your input, put that was not what I was after. But, since, both you and whore failed to see my point I'll assume it was me that didn't articulate it well and leave it at that. It's funny, I remember that chem prof had a huge periodic table of elements he'd pull down for us to view and to use, if needed, during tests. One day I was looking at it and realized it was incorrect, it had an error. I pointed it out to him and he agreed, although he'd been looking at it for decades he hadn't noticed. I wouldn't know what end of that chart was up now thirty years later, but at one time I was pretty up to date. I don't need science explained to me, nor math for that matter. I was trying to make a point that someone who had read about science but had never actually done it for a living might consider useful to think about. I'll let the point go. Maybe I was being arrogant.
