"Nature is"

     

      "Nature is" in biologist Francois Jacobs word's, "an excellent tinkerer, not a divine artificer." He's is saying when we look at nature and all the other forms of organisms and molecules, we can see the mutations that are useful for there survival.


     The Panda has an extra thumb as a mutation. It helps them eat and hold their bamboo. This mutation is very helpful at times but still it is also not needed because they already have one thumb but then they have the extra one just for a little extra help.
