Homologous and Analogous Structures Review

What evidence do similarities between fossil bones and modern organisms provide?

• species that face similar environmental pressure will develop similar traits.

• homologous structures are evidence that the two species are related or shared a common ancestor

• natural selection

• adaptive structures help organisms survive in their habitat

Birds and butterflies both developed wings to allow them to fly, but they developed them independently. What type of structure does this provide an example of?

• homologous structure

• adaptive structure

• vestigial structure

• analogus structures

What is an adaptive structure?

• having a body part that has no known function

• similar structures in more than one organism because they evolved from a common ancestor

• a structure that evolved to help an organism survive in their environment

• similar structures that evolved independently in two living organisms to serve the same purpose
