Cladogenesis is a phenomenon in which the species of parents is split up into two distinct species. These newly formed species form a clade and this is a process of evolutionary splitting. The cladogenesis normally occurs when the organisms relocate to some new and distant place and when there happens much extinction due to environmental factors.
This eventually leads to bottleneck and founder effects and hence the allelic frequencies of the new species become different from that of the ancestral population. But still, the new species have equal chances of survival as well as for reproduction and due to the phenomena of mutations, genetic drift, and natural selection, they would evolve in a better way in their new environment.
