Proposed that geologic changes and processes affected evolution and that the Earth is actually extremely old 

• Darwin
• Hutton/Lyell
• Lamarck
• Linnaeus

Proposed that organisms acquire inherited characteristics from parents but thought those characteristics changed throughout a single life time; close but not quite there

• Darwin
• Hutton/Lyell
• Lamarck
• Linnaeus

Considered the “Father of Modern Taxonomy” and came up with the binomial nomenclature naming system used today

• Darwin
• Hutton/Lyell
• Lamarck
• Linnaeus

Proposed that organisms adapt and evolve through “descent with modification”; proposed a mechanism in his book about evolution; the main person we attribute the theory of evolution with

• Darwin
• Hutton/Lyell
• Lamarck
• Linnaeus

Structures that have the same evolutionary origin or ancestor even if the current appearance or function differs

• Homologous Structures
• Analogous Structures
• Vestigial Structures

Remnants of structures inherited from ancestors; no current function

• Homologous Structures
• Analogous Structures
• Vestigial Structures

Human, rats, whales, and bird forelimb (front leg or flipper or wing)

• Homologous Structures
• Analogous Structures
• Vestigial Structures

Wings of a moth and wings of a flamingo

• Homologous Structures
• Analogous Structures
• Vestigial Structures

Pelvic bones in snakes and the appendix in a human (neither are needed)

• Homologous Structures
• Analogous Structures
• Vestigial Structures

Structures that are outwardly similar in appearance but differ in evolutionary origin

• Homologous Structures
• Analogous Structures
• Vestigial Structures
