Answer:
For example, the dinosaurs' fossils helped the scientists to learn about their habits, habitats, etc.
Explanation:
Scientists greatly depend upon existing biological evidences of extinct organisms in the form of 'fossils' to study the earlier life existed within the biosphere and the geosphere.
Fossil research allows researchers to learn a great deal not only about the organisms' live form and behaviour but also the Earth's geosphere and biosphere at that time. Specially, transitional fossils are more apt to study as they demonstrate the transitional states of a fossil between the ancestral type and the descendants' recent form.
Answer:
To study the earlier life that existed within the biosphere and the geosphere, scientists rely heavily on existing biological evidences of extinct organisms in the form of 'fossils.' For example, the fossils of dinosaurs assisted scientists in learning about their habits, habitats, and so on.
Researchers can learn a lot not only about the organisms' living forms and behaviors, but also about the Earth's geosphere and biosphere at the time. Transitional fossils, in particular, are more suitable for study because they show the transitional states of a fossil between the ancestral type and the descendants' recent form.
