How do We Date Fossils?
1. Relative Dating: The deeper the fossil
______________________________________.
2. Radioactive Dating: Scientist use the _________________ of
material left in a__________________________ substance to
determine the _________________ date of the fossil.
Anatomical Structures:
1. Homologous Structures:
 Structurally the ______________ on the inside, but have different__________________________

Molecular Record:


Everyone uses the same ________________________________
The more similar the ___________________ the more recent the _____________________
ancestor.
Artificial Selection:


How do we know natural selection can change a population?
we can recreate _____________________________________
Examples include: ____________________ __________________ __________________ ________________
