In the 1920’s, two men named Alexander Oparin and J.B.S. Haldine independently developed the first extensive hypothesis about how life may have originated (BSCS). Developing an idea called the Heterotroph Hypothesis, they assumed that life processes developed very gradually (BSCS). The first organisms were heterotrophs, while Autotrophs evolved later, and photosynthesis resulted in the oxygen - rich atmosphere of today (BSCS, MP). Both Oparine and Haldine’s thoughts on the b

The earliest fossils are interpreted to be prokaryotes. Prokaryotes are organisms that lack a membrane enclosing in their DNA (BSCS). As told before, the first organisms were probably heterotrophs, and because the early earth lacked free oxygen gas those organisms were anaerobic. Carl Wose suggested that the first organisms were methanogens. Methanogens are anaerobic bacteria that obtain energy by combining carbon dioxide and hydrogen to produce methane gas (BSCS).

Yellowstone National Park has lots of geothermal displays, which still exist today. Yellowstone’s geysers shoot tremendous amounts of water, and there is also punk pots and mud volcanoes. You can not go near these, because they are highly acidic, a pH1.

To find out about life, we must look into the ocean floor where we found geothermal activity. An organism called a “black smoker” released tremendous heat with lots of bacteria who get energy from mineral rich water.

In conclusion, i think that most likely the theory of the Halley’s comet could have worked, because to me it seems to be the most logic and scientifically correct. The Big bang theory resulted in helping out the Halley’s comet, so I figured that possible this theory of formeldeheyde being found in the tail of Halley’s comet bringing precurser molecules to the earth was correct. I think this could be more universally accepted by the scientific communtiy because what happens in space can now be invesitgated becuse of the new tecnology we have developed. We can possibly and hopefully, answer the question on how life actually was formed. Maybe we’ll never know, but as long as we have scientists, there is always a chance. The significance of the copyright dates of these sources was to show that I did not plagerize this text, and that I got my information from either my text book (BSCS) 1996 , the film Life beyond Earth (L.B.E), 1999, the second film Mirical Planet (MP) 1997, and the article “First Cell” (deamer) 1995.

The earliest micro fossils are of single celled organisms forming minute filaments (BSCS). in 1976 an exciting discovery was made in the North Pole. A scientist found the oldest fossil creation that was dated to be around 3.5 billion years
