French scientists have used a new microscopic technique to observe the beginning of life, in this case of a zebrafish. The new technique, published in Science allows rapid capture of microscopic images, which can be stitched together to form videos. Nature"s blog has more details.

Here is one of the videos, showing the zebrafish from a one-cell embryo to the 512-cell stage.

Now if this is considered the "beginning of life" for a zebrafish, starting at the one-cell embryo stage, what does that say about the human embryo?
