For example, the dinosaurs' fossils helped the scientists to learn about their habits, habitats, etc.
<u>Explanation:</u>
Scientists greatly depend upon existingbiologicalevidences of extinct organisms in the form of 'fossils' to study the earlier lifeexisted 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 thattime. Specially, transitional fossils are more apt to study as they demonstrate the transitionalstates of a fossil between the ancestral type and the descendants' recent form.
