The affinities of all the beings of the same
class have sometimes be represented by a great
tree. I believe this simile largely speaks the
truth The green and budding twigs may
represent existing species and those produced
during former years may represent the long
succession of extinct species.. .the great Tree
of Life.covers the earth with ever-branching and
beautiful ramifications
