Special Creation

Back 2

Non-Scientific theory that life-forms have been put on earth by divine forces.

Front 3

Reducing Atmosphere
-7 compounds in Prebiotic Atmosphere
-Reason it is referred to as a "reducing atmosphere"

Back 3

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

Front 4

Where did Life originate

Back 4

Ocean's Edge
Deep-Sea Vents
Deep in Earth's Crust

Front 5

Heredity

Back 5

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

Back 7

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

Hint 7

5 statements

1-age
2-all orgs have
3-daughter
4-speed
5-major agent

Back 8

1) At the Ocean's Edge
2) Deep in the Earth's Crust
3) At Deep-Sea Vents

Front 9

The Miller-Urey Experiment.
1) What Year?
2) What was the objective?

Back 9

1) 1953
2) To recreate earth's early atmosphere to attempt to see what kinds of organic molecules might have been produced

Front 10

Which Molecule came First?
RNA World.
Give evidence why

Back 10

Recent studies show RNA in ribosomes can act like an enzyme. If it can, why do we need proteins?

Front 11

Alexander Oparin
What did he do?
1)Hypothesis
2)Theory- whatd it say
3)When?

Back 11

1)First "bubble hypothesis"
2)Theory of Primary Abiogenesis:
said that all cells come from previously existing cells, except for the "primary" (first) ones
3) mid 1930s
