Question

Describe paleontological evidence of organic evolution.

Accepted Answer

Fossils are the traces and remains of animals, plants, bacteria, fungi, and single-celled living things that provide evidence of the evolutionary history of organisms. Palaeontology is the research of the history of life on Earth based on fossils. The fossil remains are used by palaeontologists to learn various features of extinct and existing organisms. They determine the age of fossils using techniques like radiometric dating. Individual fossils may comprise information about the life of an organism and the atmosphere. Fossils are the most convincing evidence of organic evolution.

There are different types of fossils discovered on earth. They are body fossils, molecular fossils, trace fossils, carbon fossils, and pseudofossils. Body fossils are the traces of the body parts of early life forms that provide information regarding the appearance. Molecular fossils are organic molecules of living bodies.
