What is an analogous structure?
Similar structures inherited from a common ancestor
Smaller or less functional structures in a closely related species

How do fossils provide evidence of evolution?
They show us how species have stayed the same over time
They show us how species have changed over time, there for we can compare them to modern species
They show us bones, that's it
This is not a piece of evidence of evolution

What is an vestigial structure?
Similar structures inherited from a common ancestor
Smaller or less functional structures in a closely related species
