What is suggested by the anatomical similarity of different species of vertebrates?

• no evolutionary relationships between the groups

• recent common ancestry

• similar environments in the past

• evolution from a distant common ancestor

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

the hind leg bones in a whale are examples of

• homologous structures
• analogous structures
• fossils
• vestigals

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures
• Embryology
• Vestigial Organs

Evolutionary Similarities that can be seen in organisms by comparing their DNA is called-

• Biochemical Similarities
• Embryology
• Vestigial Structures
• Homologous Structures

Tags

NGSS.HS-LS4-1

What is this an example of?

• vestigial structures
• embryology
• homologous structures
• fossil record

Tags

NGSS.HS-LS4-1

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

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

• vestigial structures
• homologous structures
• adaptive radiation
• fossil
