1. Who were the major scientists that developed the background information
necessary for Darwin to develop his theory, and what did each scientist
Plato and Aristotle
believed that species were immutable
studied fossils and recognized that they were extinct, and older
fossils were in deeper rocks, but still thought species immutable.
In the early 1800’s,
realized geological formations were due to long
developed the first theory for evolution, that structures evolved as
they were used more. Giraffe’s neck is the classic example
2. How did Darwin’s early travels contribute to his ideas?
Biogeographical differences in fauna and adaptive radiations suggested evolution
by natural selection.
3. Be able to list the major assumptions (observations) and predictions of
Darwin’s theory of natural selection.
Populations could, but don’t increase b/c resources are limiting, so only
the most fit offspring survive, causing long-term increases in frequency of
adaptations in populations.
4. Discuss how artificial selection, pepper moths, biogeography, homologies,
