[ch3] Handy Genes

The reason why I enjoy reading this book is because Neil Shubin gives true facts based on his experience.  Even though he has to use some professional words, I can easily understand what he tries to convey. 
"A strip of tissue at the extreme end of the limb bud is essential for all limb development. Remove it, and development stops" 
I apparently knew that change in a tissue could affect our body, but I was amazed to realize that even small part of tissue can transform our limb greatly.  More exciting thing is that when the chicken's pinky side of a limb bud is transplanted, the other side has the "full duplicate set of digits" as the transplanted side. How Awful is this?? If I have a chance to be reborn I would like to have ten fingers each side!!(No Joke)
I always have wondered why our fingers look different, especially thumb and pinky. However, by reading this chapter, I finally learned that ZPA was the factor that made the difference.  Every time I think about human being's body, I believe that God has made human since it is so detailed and delicate.
