Evolution - Change Over Time

What determines how closely related two species are?

• how recently they shared a common ancestor
• how closely they live to each other
• the carbon outline of the organism
• the relative order in the fossil record

Studying the relationship between organisms by comparing their structures

• biological evolution
• fossil record
• comparative anatomy 
• variation

Which process forms fossils?

• strutural
• variation
• carbonization
• mineralization

Patterns in the fossil record show that species on Earth

• always stay the same
• adapt to all environmental change
• change over time

Which structure is homologous to the human arm?

• fish's gill
• bird's bill
• insect's wing
• bat's wing

An example of a fossil formed by mineralization is

• a piece of petrified wood
• mammoth in ice
• insect in amber
• carbon outline of a fern

Homologous body parts do NOT always have similar

• structures
• locations
• functions

Which situation offers evidence of extinction?

• presence of identical fossils throughout the fossil record
• disappearance of a type of fossil in the fossil record
• appearance of a new species in the fossil record
• appearance of several fossils with similar body plans

The sudden disappearance of a type of fossil in the fossil record is evidence of 

• embryology
• extinction
• comparative anatomy

What was the name of the ship on which Darwin traveled?

• Nimitz
• Retriever
• Beagle
