Brilliant video from Edge.org.
Lewis Wolpert, Professor of Biology as Applied to Medicine in the Department of Anatomy and Developmental Biology of University College, London, gives a brief walk-thru of some of the latest developments in embryology.
Cell biology is among the most mysterious and fascinating areas in science. So how do cells know to grow a hand instead of an elbow? Wolpert suggest a “buffer zone” that directs anatomical construction based on timing. The experiments referenced in the video support the hypothesis – just amazing!
