More than 80 years have passed since the German scientist Hans Spemann conducted his famous experiment that laid the foundations for the field of embryonic development. After dividing a salamander embryo in half, Spemann noticed that one half - specifically, the half that gives rise to the salamander's 'belly' (ventral) starts to wither away. However, the other 'back' (dorsal) half that develops into its head, brain and spinal cord, continues to grow. (source: sciencedaily.com)
