The molecules that formed the remains gets replaced my minerals.
Carbonization: a fossil forms when a dead organism is compressed over time and pressure drives off the organism's liquids and gases.
Cast: If the impression gets filled with sediments that hardens the rock  
Molds and casts only show the external features of an organism. 
There have been 5 mass extinctions

Naturalist- A person who studies plants and animals by observing them.
Studies turtles and other plants on the island of Galapagos.
Adaptation- characteristic of a species that enables a species to survive in its environment
3 adaptation levels--
1.) Structural Adaptations which include shape, size, and color + any other physical features
2.) Behavioral Adaptations which include the way organisms act, hunt, + many others.

Comparative Anatomy- Study of how close a species is to another along with its differences.
Homologous Structure- Body parts that are same is position (structure) but different in functions. 
Analogous Structure- Similar in Function different is position (structure)
Vestigial Structures- Body parts that have lost their original function.
Whales have a tiny pelvic bone, which is a vestigial structure for walking on land.
