Evidence for Evolution Test

How does embryology support the Theory of Evolution?

• It shows that they have a common ancestor because of their similarities.
•          I'm not sure.
• Animals change over time. 

A change in the inherited characteristics of an organism over time is ________

• evolution.
• development.
• growth.
• ancestry.

The most recent ancestral form or species from which two different species evolved is known as ________________________.

• a common ancestor.
• an embryonic stage.
• development.
• evolution.

In stage one (top row) of these embryos, most of the embryos________

• look very similar.
• have very different features.
• show different stages of development.
• have only a tail if they are non-human.

In the the third embryonic stage (bottom row), mammal embryos _____

• have more characteristics in common with each other than with reptiles or birds.
• are still hard to tell from reptiles and birds.
• have the same features as fish, reptiles, and birds.
• do not have tails.
