GEOLOGY

Detailed explanation-1: -New fossil discoveries supported Darwin’s theory that creatures living in the distant past were different from, yet sometimes interconnected with, those living today. This theory allowed paleontologists to study living organisms for clues to understanding fossil evidence.

Detailed explanation-2: -The fossil record Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution, which states that simple life forms gradually evolved into more complex ones.

Detailed explanation-3: -A paleontologist collects as many fossils as possible from a rock or sediment. Once the fossils are prepared by scraping and cleaning, they are sorted by geometry. Fossils with very similar geometry are assumed to belong to a single species.

Detailed explanation-4: -Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.

Detailed explanation-5: -Paleontologists use fossils to learn about the biology, behavior, and evolution of ancient organisms, as well as the environments in which they lived. They also use fossils to study the Earth’s geologic history, including the evolution of the planet and the changes it has undergone over time.
