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

• adaptation
• sepeciation
• evolution

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

What type of structures are these?

• homologous
• vestigial 
• analogous
• fossil

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

Tags

NGSS.MS-LS4-2

If two organisms have similar traits of DNA they probably

• share a common ancestor

• share a common environment

• share a common population

• speciation

What does Darwin's theory of evolution suggest?

• species change over time
• extinct species are not related to living species
• different species can interbreed
• animals that look alike are most closely related
