Scientists may also classify plants on the basis of seeds. Some plants, for example, pinyon pines that grow at some of the higher desert elevations produce uncovered seeds that develop within the plant’s cones. Other plants such as desert grasses and some flowering plants produce seeds each w...
Why is the geologic column useful to earth scientists? How is botany evidence collected? Why are chronospecies only described from fossils? How are sedimentary rocks used in everyday life? How do scientist classify soils? How can scientists tell how closely related two organisms are?
The amount of research in this area is truly remarkable and is teaching scientists amazing things about DNA. The following links give you a taste of that research, and are interesting if you would like to learn more about these topics: Maize as a model for evolution Genomes Online Database ...

Watch for homologies. When classifying plants and animals, scientists look for homologies, or common physical traits such as your arm and a bird's wing, that are inherited from a common ancestor. If the organisms share multiple homologies, they are likely related. ...
have two benefits. They help archaeologists produce better models and interpretations of past cities; and, they help other urban scientists understand the deep history of cities and urban life. This approach allows new research findings on ancient cities to contribute to urban sustainability science ...
