3. Evidence for Evolution
What do you notice about these embryos?

4. Embryology
Embryo is an unborn (or unhatched) animal or human young in its earliest phases. 
Embryos of many different kinds of animals look very similar and it is often difficult to tell them apart. 
Many traits of one type of animal appear in the embryo of another type of animal.

5. What is this?

6. What are fossils?
Fossils are any remains of once-living things.

7. How do you read fossil layers?
Newer rock layers form at the top.
The oldest layers are at the bottom.

8. What information can fossil layers tell us?
What the environment was like
When there were extinctions and mass extinctions
When new species appeared
Comparing fossils from older rock layers to those from younger rock layers, reveals what changes the earth and living things have gone through.
