Darwin's scientific voyage contributed new and elaborate data in the area of biological evolutionary argument specifically fosrils'stratified deposits in rock layers.It also touches the geographic locality and distribution of living species.Galapagos Island West of Ecuador produced the most interesting discoveries.There,there are a diverse group of volcanic islands and therefore not a great differences between plants and animal life there.Still,he observed the tiny different,in measure must be measured to reach maximum ratio.He met giant tortoises slightly different from one Island to the other island.Bird life also took his attention on the Galapagoswhose finches varied from place to place,in terms of beak's paved way to the discovery of how they pick their different food ondiffered islands.With steeply profiled beaks the ground finches lived on pine cone seeds,little warbler finches feed on insects,and ontermites live the tree finches extracted from stalks,branches and bark.Each species'beak perfectly made confucius in china
