Fossils and Comparative Anatomy

What is the definition of fossilization?

• the process of an animal or plant being preserved in a hard, petrified form

• pressure removes the organism’s liquids and gases

• the body gets buried and minerals turn the organism into a rock form

• preserved evidence of the activity of an organism

what is comparative anatomy?

• body parts of organisms that are similar in structure and position but different in function

• body parts that perform a similar function but differ in structure

• the study of similarities and differences among structures if living species

• various cells, tissues, and organs in a body which no longer serve a function
