2. homologous
3. adaptive
4. radioactive
_____ 7- Radioactive dating is a method used to do what?

2- determine how much radiation is in an organism
3- find the age of a fossil
4- locate fossil deposits
8- Fossils are usually found in ______________________________ rocks.
9- The structures of fossils resemble many present-day organisms, so paleontologists infer
that they had the same ___________________________ as that of present-day organisms

and living things is called the:

down is the:
1. half-time 2. isotope 3. half-life 4. relative
