Uniformitarianism
The belief that the earth is very old & that the present is the key to understanding the past
Catastrophism
Extreme natural disaster cause mass extinction (ex. hurricane)

What is early cultural evolutionism (rejected eurocentric view)?
Savagery —> Barbanism —> Civilization
____________ doesn’t evolve & is not biological
Cultural
What is lamarekian / transformatinal evolution?
Individuals evolved to become more complex ( Choose which traits to evolved & pass them down to offspring)
________________________ eradicates plato’s fixed specied but relies on aristole’s great chain
Lamarakian/transformatinal evolution
Darwin Natural Selection
Similar species share a common ancestry (Variation within population)
Natural Selections occurs without _________________
Human Inference
Unnatural Selections
Occurs with human interference/ selection (ex. Dog breeding)
