Studying the similarities in organisms development 

• DNA
• Embryonic 
• Vestigial 
• Homologous 

The similarities of organisms in which two areas numbered in the picture provide the best evidence for common ancestry? HINT Similar species in an are means they are more closely related

• 1 and 2
• 3 and 4
• 5 and 6
• 7 and 8

What is this an example of?

• vestigial structures
• embryology
• homologous structures
• fossil record

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

The fossil record help scientists

• better understand the kinds of organisms that lived in the past

• better understand how the environment has changed over time

• better understand how organisms have evolved over time

• all of the above
