I'll list:
Science and Stuff
Evolution change and database is based on the average of a curve. Other words, the curve of the graph are usually taken as a line from the lowest to the highest point. The prediction of change are based on one aspect.
That means, the theory assume (check the dictionary if you do not know) that the weather is constant and do not change. Make sure the cookies setting is low so that people do not know you are checking for a word (only if you do not want to be embarrased by the intellectuals). The percentage is really a rough yet close estimate of how something is done.
How cells are created
Funny thing how this post got started. I was just reading the cell-evolution of the first organism by Joseph Panno, Ph.D. to catch up to the upcoming biology test.
I know one thing that is true about the whole evolution. Some famous scientists called Urey-Miller invented a model demostrating how things are suppose to go. It have water (H2O), CH4, NH3, and H2. Urey-Miller then boiled the water and with the substances, they formed some amino acids and peptides, and some other sort of chains. Check the wikipedia for Urey-Miller model or some sort of search engines like ask, google, teoma, yahoo, metacrawler (my favorite), dogpile, ixquick. After this, many other live things are created by the scientists. To answer your question, it is probably a storm of all of the combination of the substances that mixed and is poured randomly toward the earth. Or mixed within the water or substances just mixed, combined and boom! something forms! Take chemistry and try out the model yourself. It might be handy to have a bio dictionary beside you to tell you what you've made. Now the water wave bubble theory is shady, and I'll have to say, it may or may not exsist. Maybe it only exsist in once a while.
DNA and RNA
better research it. People belive RNA is formed by the chemical substance from the enzyme protein reverse transcriptae can copy DNA into a RNA.
Transition Species
No idea. Probably because the earth changed its landscapes so much that only certain very obvious bones of past animals can be found and analyzed. The smaller ones are probably swallowed into the earth's magma and recycled to make other rocks.
