ABSTRACT
The concept of evolution an attempt to interpret natural processes in terms of individual growth. Evolution means change culminating in an end which is the result of the process and is qualitatively new. In the evolutionary theories of modern biology, it is precisely the problems of the origination of new species, and of special character of the relations between species and its environment by which the process is conditioned, that have attracted almost exclusive attention. Evolution obviously involves the two concepts of change and the dependence of the order and direction of change upon determinate conditions. But an evolutionary process is never a mere orderly sequence of changes. Development or evolution, definitely implies the culmination of a process of change in the establishment of a state of things which is relatively new, and implies, that the relatively new state of things may truly be regarded as the end or completion of the special process of change.
