Learn a little developmental biology

This is a cool video from a textbook publisher (Molecular Biology of the Cell, a very good text) illustrating how Spemann/Mangold’s famous organizer experiment was done. Also cool: those are apparently Edward De Robertis’ hands doing the experiment.

You’ll only know what the heck I’m talking about if you remember JJ from the television show Good Times, and it’s such a pathetic joke it’s only going to appeal to grade schoolers.
