Research different theories on the origin of life?

Answer 1

if your not religious, comets brought ice, the ice melted and then with other compounds, elements, and heat life came to be or maybe from deep ocean vents where there isn't light but there is heat and the inards of earth Some believe God made the whole earth, however their are many theories. It all depends on your religious beliefs, or lack there of.

Answer 2

the 2 mains theories are the creationist and the evolutionist theories. the evolutionist theories says that there was a huge bang in space that created all the planets, then there was a zap of lightning which created a puddle with a single in it, that cell then made more cells which eventually crawled out of the puddle and made every living thing on this planet. then the creationist theory says that god created everything. so if you're wondering which one is true its alot easier to have faith that there is 1 god who made everything then one cell making every life thing on earth

Mr. Bushido, you are talking nonsense. Evolution does not say anything about the origin of life: it is concerned how life improves ONLY AFTER it has emerged. The theory concerning the emergence of life on the planet is Abiogenesis. After the Big Bang created all the matter in the universe and a tiny portion of this matter coalesced into our planet and its atmosphere, basic chemistry started. Take into consideration that at the time, the mean planetary surface temperature was much higher than now (close to 90 degrees Celsius if I remember correctly). At such high temperatures, chemical reactions proceed much faster and first amino acids of the simplest kind, nucleotides, even simple sugars (which we still use) were formed. Miller-Urey experiment has proven that necessary building blocks of life can emerge from humble chemical reactions. These first 'living things' were nowhere near modern complexity we see today even in a single bacterium. They were merely amino acid/nucleotide chains that catalysed their own replication. These systems in time associated themselves with similar systems, leading to more and more complicated systems of life.

Answer 3

on basis of different theoris on orgin of life there is a clear evidence of various life forms evoulting from some other animal forms.. this means that there must be a single life form may be a prokaryote which transformed into various life forms........but we have a conflict on the 1st life form... a valuable note here is that all life forms are made of only chemicals and life runs because of chemical changes and reactions........ it may be obscre to understand but think deep to get the answer.... the atoms on chemical interaction may formed molecules which by external forces changed to gather more molecules and finally transformed into a primitive type of life... there after everyone knows the life forms origin.. "there is a clear transformation of life from chemicals.. we have atoms dr.rajeshkumarmadras veterinery college chennai_7

Answer 4

The two most widely-known are the tradition of Creation, and the theory of Evolution. According to the theory of Evolution, life developed by random processes, especially mutations.

The narrative of Divine Creation, which is contained in Genesis ch.1 and 2, states that God created the universe. This teaches us that God exists, that our lives and the world are not random, and that the created things may be assumed to contain vast wisdom in their beautiful and purposeful design. (In recent decades, this wisdom has indeed been partially revealed, through increasingly powerful microscopes.)Evolution through random mutations, on the other hand, may be understood as implying that life is an accident, that perceived beauty and wisdom are ultimately purposeless, and that our instinctive yearning for the Eternal is just an electrical impulse in our brain.
