What are homologous structures?

• Structures with similar functions but different origins

• Similar structures that suggest evidence of common ancestry

• Structures that have evolved independently

• Structures that are identical in all species

Tags

NGSS.MS-LS4-2

What does the presence of homologous structures suggest about different species?

• They have no evolutionary relationship

• They share a common ancestor

• They evolved in the same environment

• They have identical DNA

What can vestigial structures provide evidence of?

• Convergent evolution

• Parallel evolution

• Divergent evolution

• No evolutionary significance

Tags

NGSS.HS-LS4-1

What are analogous structures?

• Structures that are similar due to common ancestry

• Structures that evolved independently in different organisms for similar purposes

• Structures that are identical in all organisms

• Structures that serve different purposes in similar environments
