I have read various books on evolution and the early earth and here's my interpration. Please correct and help me get the FACTS straight. The early earth had an atmosphere of: water vapor, carbon dioxide, phosphate salts, lightning, UV radiation, and lots of heat. All this helped to create amino acids, fatty lipids, nucleotide bases, mineral salts all falling together to form a thick soup over many years. The amino acids, when activated by the energy of the atmosphere (lightning, UV), behaved like magnets and began to attract to one another in various orders helping to form various types of proteins. At the same time, the 4 nucleotide bases (A,T,G,C) combined with sugar phosphates and with energy from the atmosphere began to drift randomly to join and form a nucleic acid chain. Soon the complimentary side of the nucleic acid chain joined to make the chain more stable forming the DNA double stranded chain. Some of the various proteins being formed turned out to be useful. Some could check out the nucleic acid chain and begin transcribing it to an equivalent amino acid sequence (a new protein). Also, despite the fact that the nucleic acid chain could self replicate by easily attracting a complimentary nucleotide base (A<->T, G<->C), some proteins helped improve the replication dramatically in speed and accuracy. By luck, fatty lipids formed around some DNA chains and proteins thereby helping to make them contained in a less erratic environment. As time goes on, many DNA chains and proteins are wiped out by the violent soup and atmosphere but some continue to survive. By luck, through various DNA replication errors, various new useful proteins come about for a cell helping in its coninued survival. These proteins give the cell an edge over other cells and this cell is able to replicate its offspring quicker and better than everyone else. Soon this cell and its offspring become the dominate while the others die off. Thanks to replication errors, radiation, chemicals, random adding/deleting because of the violent enviroment/an enzyme, etc. the DNA chain gets many variations in its sequence and expands in size. With the changing DNA code comes more variety to help the cell survive and dominate. The cell (bacteria like) soon becomes more and more complex in its continued game of survive and thrive in this certain environment. With incredible mutations and replications over many millions of years and the enviroment playing the unforgiving NATURAL SELECTOR of who is best fit for the environment to continue and dominate, incredibly complex organisms appear such as fish. Eventually over many more years mutation and fittest offspring lead to the land animals... Is the above an accurate portrayal of how life began or did I mess up (a bit) somewhere? Please, if you can correct me, I'd be forever in debt to you. THANKS! [Could you reply to me through EMAIL, thanks] Jim. (ljaques@odyssey.on.ca)
