The greater the depreciation of genes impacts on the cohesion of species. This factor reduces communication and recognition between related species. Natural selection has not hindered the evolution rather it allowed species to adapt to a method of learning among animals at young age in sign language.
Evolution is a complex lottery game where the rules are imposed by mechanism of natural selection. Convergent evolution illustrates the momentum of ancestors to survive in the changing environmental pressure. Cohesive theory shows each related species retains the ancestors while analogues evolution shows completely different species. The diversity of species is the result of genetic drift as a trade to live with new design. The inevitable decisions prevent new species to be related again. The mutations have greatly affected the biological recognition between individuals. Natural selection is not a law to improve the fitter species to be the dominant fitter species but the natural clock to drive the biological reaction forward but never reach conclusion. Living fossils refusal to change signify the environment has not challenged the animal and maybe the species might have reached its final modification also the populations are more sporadic but they inhabit similar niches around the world. The world might retain areas where evolution reactions have not activated.
