What does Darwin's theory of evolution by natural selection explain?

• Patterns in behavior and habitat

• Patterns in climate and geography

• Patterns in inherited traits and new species emergence

• Patterns in DNA and RNA

What are derived traits?

• Similar structures inherited from a common ancestor

• Traits that are reduced forms of functional structures

• Traits that are shared by species with a common ancestor

• Newly evolved traits that have not appeared in ancestors

How are derived traits and ancestral traits different?

• Derived traits are reduced forms of functional structures, while ancestral traits are similar structures inherited from a common ancestor

• Derived traits are similar structures inherited from a common ancestor, while ancestral traits are newly evolved

• Derived traits are newly evolved, while ancestral traits are shared by species with a common ancestor

• Derived traits are shared by species with a common ancestor, while ancestral traits are newly evolved

What are Vestigial structures?

• Traits that are shared by species with a common ancestor

• Newly evolved traits that have not appeared in ancestors

• Similar structures inherited from a common ancestor

• Features that are reduced forms of functional structures in other organisms and maybe come small or disappear.

What are Analogous Structures?

• Structures with the same function but different construction

• Similar structures inherited from a common ancestor

• Newly evolved traits that have not appeared in ancestors

• Features that are reduced forms of functional structures in other organisms

What is an Embryo?

• An early stage of development in organisms

• Newly evolved traits that have not appeared in ancestors

• Features that are reduced forms of functional structures in other organisms

• Similar structures inherited from a common ancestor
