How do fossils show your development as a species?

Animal and plant fossils develop when upon death they are rather quickly covered in water or sediment or sand which helps prevent them from becoming prey to scavengers or rot. Even volcanic ash from an eruption can be the blanketing medium. Flesh is often stripped from the bones of animals by bacterial action before fossilization. Sometimes tree sap traps small animals like insects and preserves them in amber rock. Sea animals with hard shells leave imprints of these parts preserved in stone, or the hard parts may be replaced with minerals such as calcite, quartz, or pyrite. Mineral replacement fossilization can take an amazingly short period of time, on the order of decades in some instances.
