- remarked upon first hearing Darwin’s ideas of natural selection
A
Thomas Henry Huxley (1825-1895)
2
Q
what did Huxley become
A
Darwin’s Bulldog
3
Q
- founder of comparative anatomy
- coupling and compatibility of parts and function they perform

- harmonized parts for an organism to perform properly
A
Georges Cuvier (1769-1832)
4
Q
- supported the idea that species were immutable but emphasized that homologies should be further explained
- proposed archetypes
A
Richard Owen (1804-1892)
5
Q
- biological blueprint or underlying body plan of organisms
- proposed by Richard Owen
A
archetypes
6
Q
repeating series of vertebral untis as an underlying pattern of the vertebrate body
A
vertebrate archetype
7
Q
external architect of animal design to fit current purposes
A
natural selection

- form and function
- integration of structure and function to animal design as possible blueprint for new forms
A
morphology

“structure with function”
A
George Cuvier

11
Q
“structural change over time (evolution)”
A
Thomas Henry Huxley
12
