|
Chain of Being
|
- all species were created in one place at one time
-each organism is distinct from all the rest (Aristotle) |
|
Uniformitarianism
|
Process of erosion & sedimentation produce changes on earth
(Hutton) |
|
Catastrophism
|
Catastrophes occurred and survivors repopulated
(Cuvier) |
|
Unknown ‘fluida’
|
Life was created long ago in a simple state and has just improved
(Lamarck) |
|
Theory of Uniformity
|
Subtle, repetitive processes of change had shaped Earth
(Lyell) |
|
Principle of Superposition
|
-Layers closest to the top were younger.
-Bottom layers held older fossils. |
|
Descent w/ Modification
|
Gradual change from an ancestral form
(Darwin) |
|
Natural Selection
|
Differences in reproduction among individuals of a population vary in shared traits
|
|
Aritificial Selection
|
Human Select Trait

|
Evolution & Population (4)
|
1.Populations Evolve
2.Biological evolution only changes population 3. Traits in population vary among indivduals 4. Evolution is change in frequency of traits. |
