What best describes a vestigial structure?

• Body parts with the same function but different structures

• Body parts that no longer serve a purpose

• Body parts adapted to the organisms environment

• Body parts with different functions but the same structures

What do vestigial structures provide evidence of?

• What the organisms ancestors adaptations were

• That an organism shares a common ancestor with another

• That the organism does not share common ancestors with others

• How old an organism is

Mutations can introduce new traits to a population. The mutation may eventually become common within the population, but only if it -

• increases genetic diversity

• increases fitness for the environment

• decreases how different individuals are from one another

• was caused by nature instead of human interference
