| where are most fossils found? | sedimentary rocks |
| fossil | remains of life from an earlier time |
| Most important source of information for evolution? | fossils |
| How do we know what organisms used to live on Earth? | the Fossil Record |
| How do fossils and comparative anatomy support evolution? | Comparing fossils to living organisms helps to see both similarities (showing a relationship) and differences (showing adaptations) |
| What are 2 important adaptations organisms need to move from the ocean to land? | air breathing lungs and arms and legs |
| List 2 biological adaptations for humans.. | walking upright freeing the hands for other uses, and the opposable thumb |
