What would happen if there was zero variation between all of the organisms on earth?

End of Evolution, End of natural selection Among organisms and End of Adaptability amongst species of organisms

Explanation:

Variation is likened to be the opposite between organisms that is supposed to fosters continuous or discontinuous cohabitation.

Variation can be sourced through Gene mutation, genes immigration or Gene recombination. All these three allow interference of genes which in turn greatly affects Evolution, Adaptability and Survival.

With all that mentioned, a ZERO VARIATION will of course bring an end to EVOLUTION, adaptation and natural course of order amongst organisms
