Answer:
Divergent evolution is the evolution of a
number of different forms of animals or plants froms of a common ancestral
form. The driving force behind, it is adaptations to newly involved habitat and
the prevailing environmental conditions there. As the original population
increases in size, it spreads out from its centre of origin to exploit new habitas
and food resources.
In this results in a number of
populations each adapted to its particular habitat eventually these populations
will differ from each other sufficiently to become new species.
A good example of this process
is the evolution of the Australian marsupials into species adapted as
carnivores, herbivores, burrowers, fliers, etc. Another example is that of
peritadactyl limb in
mammals.
The flipper of a seal, wing of a
bat, forelimb of a male, front legs of horse and the arm of a man perform
different functions, but exhibit the same structural plan including same pentadactyl
pattern of bones.
