Francois Jacob says "Nature is a excellent tinker, not a divine artificer." This means that nature will make you change somethings to survive but it is not perfect and may not even be needed to change in some cases. With the pandas thumb it is a contrivance in which it is modified for new use. The pandas thumb is not like human thumbs but it helps the panda eat the bamboo around him or her. This is like were it says in the quote that nature is a tinker. The panda body changed to survive and feed its self. Just like the orchids they trap insects and pollen so they can be fertilized and make other orchids. This is a new method so they can survive and reproduce.
