I can't decide if this is for real or a joke. The site of the company that's buying the DNA (www.NewLineGenetics.com) looks pretty solid, but if they're telling the truth, it's amazing what they can do.

As a process of nature, natural selection was familiar to biologists before Darwin, who defined it as a "mechanism that keeps species unchanging without being corrupted". Darwin was the first person to put forward the assertion that this process had evolutionary power and he then erected his entire theory on the foundation of this assertion. However, since Darwin’s time, there has not been a single shred of evidence put forward to show that natural selection causes living beings to evolve. Colin Patterson, the senior palaeontologist of the Museum of Natural History in England, stresses that natural selection has never been observed to have the power to cause things to evolve:
“No one has ever produced a species by mechanisms of natural selection. No one has ever got near it and most of the current argument in neo-Darwinism is about this question1.”
Natural selection holds that those living things that are more suited to the natural conditions of their habitats will prevail by having offspring that will survive, whereas those that are unfit will disappear. For example, in a deer herd under the threat of wild animals, naturally those that can run faster will survive. That is true. But no matter how long this process goes on, it will not transform those deer into another living species. The deer will always remain deer.
When we look at the few incidents the evolutionists have put forth as observed examples of natural selection, we see that these are nothing but a simple attempt to hoodwink.

does anyone know the substance that should be used for the experiment where you have1ml of 1% concentrated substance(im going to call it substance X) in a test tube, you add 9ml distilled water, mix and subract 1ml from the test tube with a pipette.you empty the pipette into test tube 2 and add 2 drops of iodine to test tube 1. you repeat this for about 5 test tubes and then test how strong the colour is. it was a practical i did in biology but i can't remember the name of it.
i'm supposed to write a method for it but can't remember what substance we were using.
if anyone managed to make sense of what i just said, could you please help me out?
