"The earliest bird known, although obviously a bird, with 

 wings and feathers, differs in many ways from modern birds. 

 It has large teeth; its tail was not a fan, but a double row of 

 feathers on either side of a long pointed axis o^ a bone; and 

 most remarkable of all, it had on its wings, besides feathers, 

 three separately movable fingers ending in claws, by whose aid 

 it doubtless scrambled about through the branches. In all these 

 ways it was less fully adapted to aerial life than are modern 

 birds." — Julian S. Huxley.
