A lot of what we know about developmental biology and human diseases has been found through the studying of embryonic development, or evolving as we age from the womb to adulthood. Scientist and inventor Manu Prakash turns his attention toward another fascinating metamorphosis: postembryonic development, when an organism completely dissolves its tissue and morphs completely -- for instance, from caterpillar to butterfly. Why did evolution take this turn?

NOTE: Comments are disabled on this video. We made this difficult decision for the TED Archive because we believe that a well-moderated conversation allows for better commentary from more people and more viewpoints. Studies show that aggressive and hateful comments silence other commenters and drive them away; unfortunately, YouTube's comment moderation tools are simply not up to the task of allowing us to monitor comments on so many videos at once. (We'd love to see this change, YouTube.) So for now, if you'd like to comment on this talk, please use Facebook, Twitter or G+ to discuss with your networks.
