Evidence of Evolution ch 11.1 17-18

The millions of fossils that scientists have collected are called the fossil

• architecture
• record
• data base
• library

Scientists infer evolutionary relationships by comparing the early development of different 

• dinosaurs
• backbones
• proteins
• organisms

Scientists infer that species with similar body structures and development patterns had a common

• environment
• predator
• ancestor
• gene

Change over time is also known as the theory of

• atomic structure
• creation
• evolution
• relativity

Structures with the same parts have different functions; suggests that organisms share a common ancestry

• vestigial structures
• homologous structures
• adaptive radiation
• fossil

If an organism has a vestigial structure, that structure likely once had a function in a(n)

• close relative
• early ancestor
• unrelated organism
• embryological stage

The process by which populations slowly change over time is called__________

• selective breeding
• adaptation
• sepeciation
• evolution

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

If two organisms have similar traits of DNA they are probably

• share a common ancestor
• share a common environment
• share a common population
• speciation

Which of the following pieces of evolution evidence contain both homologous and vestigial structures?

• fossil record
• comparing embryology
• comparing biochemistry
• comparing anatomy
