Question

Find out from newspapers and popular science articles any new fossil discoveries or controversies about evolution.

Answer 1

Fossils are the remains or signs of ancient organisms obtained from rocks. Palaeontology, the study of fossils, examines the remains of organisms from millions of years ago. The study of fossils by scientists makes it clear which kinds of organisms were present on Earth during which periods. Fossils buried in rocks and the earth’s crust are dug out. These signs or remains help us imagine the structure of organisms.

By determining the age of rocks, scientists can also determine the estimated age of fossils. Therefore, scientists consider fossils strong evidence of biological evolution. The most familiar examples of fossils are Archaeopteryx and dinosaurs. During the Mesozoic era, known as the golden age of reptiles, dinosaurs dominated the Earth.

Fossils of different types of organisms have been found in rocks of different ages, probably buried in them during the formation of that rock. They represent extinct organisms, which underscores that life on Earth has been changing. Researchers have discovered human-like bone fossils in Ethiopia and Tanzania. The history of human evolution has been known from the fossils of human ancestors.
