Reducing Atmosphere
-7 compounds in Prebiotic Atmosphere -Reason it is referred to as a "reducing atmosphere" |
1) Carbon Dioxide (CO2)
2) Nitrogen Gas (N2) 3) Water Vapor (H20) 4) Hydrogen Gas (H2) 5) Hydrogen Sulfide (H2S) 6) Ammonia (NH3) 7) Methane (CH4) -referred to as a "reduing" atmosphere because of the ample availability of hydrogen atoms and their electrons |

Where did Life originate
|
Ocean's Edge
Deep-Sea Vents Deep in Earth's Crust |

|
Heredity
|
All organisms on earth possess a genetic system that is based on the replication of a long, complex molecule called DNA. This mechanism allows for adaptation and evolution over time, and is a distinguishing characteristic of living organisms.

Darwin's Conclusions
|
1) Earth is old and organisms have changed steadily over time
2) All organisms are descendants of a single common ancestor 3) Species multiplyed by splitting into daughter species, giving diversity 4) Evolution proceeds slowly in population, not suddenly 5) Major agent of evolutionary change is natural selection |

1) What Year? 2) What was the objective? |
1) 1953
2) To recreate earth's early atmosphere to attempt to see what kinds of organic molecules might have been produced |

|
Which Molecule came First?
RNA World. Give evidence why |
Recent studies show RNA in ribosomes can act like an enzyme. If it can, why do we need proteins?
