Watch a Single Cell Become a Complex Organism in Just Six Minutes

In this time lapse filmed by Jan van IJken, the embryo of a salamander is shown transforming into a hatched tadpole, from a single cell to a complex organism in a three-week process that’s condensed into just six minutes of video.

The first stages of embryonic development are roughly the same for all animals, including humans. In the film, we can observe a universal process which normally is invisible: the very beginning of an animal’s life. A single cell is transformed into a complete, complex living organism with a beating heart and running bloodstream.
