However, it does not go far enough. At one time, proteins must have evolved or been created. They do all the work in living creatures. They make sugars, fats, and other molecules. They even help nucleic acids to work. The one thing they don't do is make other proteins. At one time, they must have come up with a way to make copies of themselves. Why don't they do it now? Maybe it is because they came up with another way. The proteins that made other proteins, we'll call them type one, may not have been very accurate at making copies of themselves. At some time, a protein may have come up with a way of using transfer ribonucleic acid (tRNA) to make other proteins. It suvived and reproduced faster than the ones that just used proteins to make proteins. We will call this type two. It will have multipied and made more tRNA's so it could hook up all the amino acids it needed to make a protein. Type two proteins made enough tRNA's until they were able to make messenger ribonucleic acid (mRNA). Then they became type three proteins. The mRNA's were able to store the information needed to make correct cop ies of the protein. These proteins were able to reproduce much faster than type one or two proteins. We will call these type three proteins. They did have a problem though, RNA needed protection from the enviroment. Some of them developed a protein coat to protect the RNA from the enviroment. These were the first viruses. Some of them survive today. We call them RNA viruses. Others of these type three proteins continued to improve the way they make proteins. They developed ribosomal RNA (rRNA) which gave them a place to make proteins very fast. Let's call them ribosomal viruses. They were eventually swallowed by bigger organisms and survive only as ribosomes. They have all three types of RNA but they do not have DNA. They did reproduce rapidly and became numberous. Some of the type three viruses invented a protein that would remove the second hydroxy group from the ribose sugar. Deoxyribose was invented. It coils up much better than RNA. It can get bigger inside the same space. It can hold more genes. One new protein added a methyl group to Uracil to make Thymadine. Thymadine is more specific than Uracil and led to fewer mistakes. This means there were more accurate copies made so more of these viruses survived. We will call them type five proteins. Some of them survive today. We call them DNA viruses. Deoxyribonucleic acid (DNA) coils in such a way that it incourages the formation of a second strand. The second strand can also hold genes. This type five virus didn't stop at the virus stage. It developed a lipid membrane and became a bacteria. Rather than go to the trouble of developing its own ribosomes, it swallowed some of the type four ribosomal viruses. They became ribosomes. The bacteria became the ancestor of all other bacteria, of blue-green algae, of archaeobateria, of fungi, of plants, and of animals.
