1. Why are fossils important to learn about? Fossils provide a record of life on Earth from as long as 1 billion years ago Help us to understand the different environments that once existed They show how organisms (animals and plants) have changed over time Changes from simpler to more complex development These records can be dated, so they are a physical representation of evolutionary progression Example: the way that ancient fish developed a bone in their jaw over time. Those representative species in any given time are what would be expected if evolution had occurred. http://www.paleoportal.org/
