Co S GDR R H H

Codeine Sulfate GDR Roxicodone Hydrocodone Heroin
Special Creation
Non-Scientific theory that life-forms have been put on earth by divine forces.
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
