Species B is less abundant than species C
Species C existed before species B
Species A and B are genetically identical
Species B descends from species A

Q. Which among the following statements are correct with respect to fossils?
- Fossils can help in tracing the evolutionary history of the organism.
- The study of fossils is called palaeontology.
- The timescale in which the organism existed can be determined by studying fossils.
- All fossils represent extinct species.
