Evidence for evolution: development of our kidneys

I am teaching about this today in my introductory evolution class, and thought Id include a video showing evidence for evolution that comes from the development of the human kidney. The video is in French, but Ill explain whats happening.

The evolutionary/developmental phenomenon of recapitulation, in which developing organisms are supposed to go through stages that reprise their evolutionary ancestry, has been in bad repute, but some of that is undeserved. (Recapitulation is often characterized with the phrase ontogeny recapitulates phylogeny, with ontogeny meaning development and phylogeny meaning order in which ancestors evolved.)
