Can Adult Stem Cells Do It All?

Scientists may have turned mouse skin cells into embryolike stem cells, but prior claims for the power of adult cells have yet to stand the test of time

If mutations occur at random over the entire sequence of a species' genome, how can a complex organ such as an eye evolve? How can all the mutations that direct the development of that organ be concentrated in the right places?
