There is a morphological enfoldment occurring on this planet. It is bringing forth some entirely new order of being. We are a privileged part of this.
The known fossil record fails to document a single example of phyletic evolution i. e. , a species becoming a new species accomplishing a major morphological transition and hence offers no evidence that the gradualistic model can be valid.
It is useful to the historian, among others, to be able to see the commonest forms of different phenomena, whether phonetic, morphological or other, and how language lives, carries on and changes over time.
The morphological characteristics of plant and animal species form the chief subject of the descriptive natural sciences and are the criteria for their classification. But not until recently has it been recognized that in living organisms, as in the realm of crystals, chemical differences parallel the variation in structure.
Each race (or variety) is characterized by a more or less distinct combination of inherited morphological, behavioral, physiological traits.
The chemical differences among various species and genera of animals and plants are certainly as significant for the history of their origins as the differences in form. If we could define clearly the differences in molecular constitution and functions of different kinds of organisms, there would be possible a more illuminating and deeper understanding of question of the evolutionary reactions of organisms than could ever be expected from morphological considerations.
