Answer:
Divergent Evolution Separate Specie Concept
Step-by-step explanation:
When the main specie gets diverged from the origin, the evolution gets into the ground. Those members of same specie were exposed to different environmental conditions and as a result and concept of divergent evolution, they adapted to it and their chromosome number get diverted and they took the role of a totally separate specie in that environment. No doubt, the DNA analysis revealed their closeness to one another but now the sister specie on the opposite side is a new specie due to divergent evolution.
