Answer 1

Hint: A fossil is any preserved, trace or impression found in any geological area. The fossils are very useful for studying history. When a fossil is found in any area, it gives the idea and evidence of the occurrence of that organism or species in that area.

Complete answer:
Fossils play an important role in providing evidence for the present day theories. The various examples of fossils are bones, shells, exoskeletons and stone imprints etc. The study of fossils is called paleontology.
According to the paleontological evidence, the fossils of the earliest man, Homo naledi was found in the regions of South Africa. Therefore, the correct answer to this question is option c Africa.
Additional information: As you know the study of fossils is called paleontology. It includes their age, their method of formation and evolutionary significance. Specimens are only counted in fossils if they are 10,000 years old. The oldest fossil is about 3.48 billion to 4.1 billion years old.
Various processes occur which lead to the fossilization like permineralization, casts and molds, authigenic mineralization, replacement and recrystallization, carbonization and bioimmuration. These fossils may vary in shape and sizes such as it may be as small as 1 micrometer or can be as huge as a dinosaur.

Note: A fossil normally preserves a portion of deceased organism, usually the portion that was partially mineralized during life such as bones, teeth etc. Fossils may also consist of marks left behind by the organism when it was alive. This is also called trace fossils.
