The video talks about the different theories that prove evolution. One of them is vestigial structures. This theory says that certain parts of organisms can be leftover unused parts from an earlier ancestor that actually used them. The video uses the tailbone in humans as an example for these. Another theory the video uses to prove evolution is homologous structures. These are structures in embryonic organisms that are similar and prove that they have a common ancestor.
