depending on the cause of speciation. A population living in the same habitat
could be separated by a physical barrier hence restricting gene flow in the population.
On the other hand, sympatric speciation refers to the formation of different species

physical separation. This could be due to differences in mating tendencies of individuals
in the population </span>
Indentifiyng species is the answer
