have connected all the past and present species of the same group into one long and branching chain of life. We ought only to look for a few links,

The abrupt manner in which whole groups of species suddenly appear in certain formations, has been urged by several

as a fatal objection to the belief in the transmutation of species. If numerous species, belonging to the same genera or families, have really started into life
