Evolution and Cladogram

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

Which conclusions are best supported by the embryo diagram?

• Organisms that share a common ancestor develop differently through the three phases of development.

• Organisms appear similar in early development because they share a common ancestor.

• Organisms that are more closely related develop faster than other organisms due to sharing a common ancestor.

• Organisms develop at similar rates because they share a common ancestor.
