Shows how modern organisms descended from common ancestors Structures that do not serve a function and are similar to those found in earlier organisms 1. Transitional Species Compares the age of fossils to each other based on the layers of rock they are found in 2. Vestigial structure 3. Fossil Record 4. Relative Dating Evidence of gradual change between a new species and its ancestor 5. Radiometric Dating Structures that related species have inherited from a common ancestor 6. Homologous Structures uses radioactive elements to narrow down the age of a fossil to a specific period

Does man evolve from monkeys? Use the cladogram of primates to defend your answer. Give a clear topic sentence, three or more relevant supporting details, and complete explanation

The fossil record shows that the first mammals evolved 220 million years ago. The supercontinent Pangaea began to break apart 200 million years ago. On which continents would you predict that fossils of the first mammals will be found?
