SPECIATION
Speciation is the process by which new species are formed from other
ancestral ones. The most widely accepted hypothesis explaining the
process of speciation is the geographical theory of speciation or
allopatric theory of speciation. According to it the first step in speciation
is reproductive isolation brought about by physical separation or
geographical separation of population (allopatric population).
