A- Spreading of same species to different and isolated environments which blocks the gene flow among the distinct populations
B. vertebrate limb of whale and elephant is one example of divergent evolution
C- Both orthologous genes and paralogous genes can be said to display divergent evolution

Micro-evolution is the term used for changes in allele frequencies that occur over time.
A) It gives rise to changes in the gene pool, which results in few changes in the same species
B) It occur above species level
C) New addition, deletion in the genetic structure, resulting in the formation of new species
