Whale Evolution

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

What is suggested by the similarity of early embryos of different species of vertebrates?

• no evolutionary relationships between the groups
• recent common ancestry
• similar environments in the past
• evolution from a distant common ancestor

• homologous structures
• adaptive radiation
• fossil

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time
