PPT-FOSSILS & EVOLUTIONARY RATE

Dr Jagdish kaur PGGCSector 11 Chandigarh SIMPLY THE CHANGES OVER TIME EVOLUTION Human Evolution The evolutionary timeline is divided into sections of time called eras which are then divided into smaller units of time called periods. What are fossils?. FOSSILS. . are. . the . preserved remains or . traces.  of animals, plants, and other organisms . that lived long ago.. When an organism dies, hard parts of the animal (bones, teeth, shells, etc.) can be preserved in rock.. Remains . of once living organisms.. Form from decay and are buried by sediment.. Sediment hardens into rock and preserves the shape of the organisms.. Fossils. Fossils . Remains. Molds. . Casts. . Charles Darwin. Father of Evolution. Proposed a way . how. evolution works.

Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. Fall 2012.
