Origin of Life - Scientific Contributions

Claim: Life only comes from life.

Evidence: The broth in the covered flask did not grow bacteria.

Claim: Life spontaneously generates (appear)

Evidence: When the flask with broth is exposed to the air, bacteria forms out of nowhere.

Claim: First life forms from naturally occurring chemical reactions.

Evidence: The results of the experiment show that through chemical reactions, amino acids (special molecules of life) were produced.

Claim: Chemical reactions take place eventually producing living cells.

Evidence: The early ocean simulated a primordial soup, rich in carbon based molecules that engage in chemical reactions.

Claim: Chloroplasts engulf mitochondrial cells and are able to do both photosynthesis and cellular respiration.

Evidence: Chloroplasts and mitochondria evolved from small bacteria that use sunlight as a source of energy.

Claim: Large cells engulfed small bacteria that could do either photosynthesis or respiration evolved into organelles.

Evidence: Over time the small bacteria within the large cell that use oxygen evolved into mitochondria and the bacteria that use sunlight evolved into chloroplast.

Amino acids spontaneously from into proteins that give rise to living things.

Naturally occurring chemical reactions of natural gases produces amino acids.
