Contrast the impact of natural selection on divergent and convergent evolution.

Divergent evolution is a collection of dissimilarities between groups which can form new species, usually a result of diffusion of same species adapted to different environs. This leads to natural selection defining the success of specific mutation. 

Basically, diffusion is the basis of molecular division that is visible in some characters of higher level of function and structure that are observable in organisms. 

Example Of Divergent Evolution- the limb of a vertebrate is a divergent evolution example. 

The limb has a common origin for different species, but has little diversion in overall structure and function. 

In divergent evolution, the reason for similarity is the common origin, as divergence from a common ancestral function or structure has not yet completely distinguished the underlying similarity. 

Convergent Evolution: 

There are many instances where different organisms that are not very closely related have developed similar adaptations for life in similar habitats. 

This phenomenon is often referred to as Convergent Evolution. 

The convergent evolution occurs when there are some type of physical or ecological drivers towards a similar method, even though the function or structure has occurred independently. 

Such as different specialities converging on a similar, common solutions from different origin of points. 

This includes analogous structures.
