A structure that serves the same purpose, but is not made in the same way is called

• a homologous structure

• an analogous Structure

• a pheryngial structure

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

Structures are similar in function but not in anatomical structure
EXAMPLE: bird wings vs. butterfly wings

• Vestigial

• Homologous

• Analogous Structures

• Embryonic

What is this an example of?

• vestigial structures

• embryology

• homologous structures

• fossil record

• Lungs for breathing air

• kidneys to clean the blood

• Pharyngeal Pouches
